Maximum length cartridge.

[MOA]

Does anybody know the maximum length cartridge that a rolling block will allow to be chambered.

[onelight]

It is limited by barrel length, any cartridge longer than the barrel will perform poorly :kidding:

[Hickory]

You are correct.
On a single shot firearm it can be anything you want it to be.

[MOA]

You are correct.
On a single shot firearm it can be anything you want it to be.

Really. That's good to hear. I guess I don't need to worry that a Remington roller will easily chamber a 45-120 3-1/4" cartridge. I was a bit conserned that the block might prevent a cartridge of that length from chambering. Hence my question. I know of no problems with shorter length cartridges, but serious concerns on the 45-120 gave me pause.

[Hickory]

On a single shot firearm it can be anything you want it to be.

Cartridge Maximum length is only important when fitting them in a magazine.
With a single shot your maximum length will be where you get the best accuracy.

[Tatume]

You are correct. On a single shot firearm it can be anything you want it to be.

That is not true. Some single shot rifles do have a maximum length. The Martini is an example. There are others.

[MOA]

Well let me ask this another way that may be clearer. As I'm sure everyone knows there is a distinct advantage to a falling block action when it comes to inserting a long cartridge over inserting the same cartridge into a rolling block action due to the block mechanism getting in the way of inserting a overly long cartridge. So, does anyone have an educated guess what the maximum length cartridge would be before the block interfered with loading the cartridge into the chamber on a Remington / Husqvarna roller.

[kootne]

With a rolling block you do have some limitations, the hammer nose is the interfering point. The length,diameter and taper of the cartridge have a bearing what will fit. A .50 x 3-1/4 probably isn't going to go without modifying the hammer nose. If you look at the hammer of a RB chambered for a shotgun shell you see what needs to be done.

[KCSO]

Actually George Nonte did this in the 70's and found out that a 3" 45 case was too long to pas the hammer nose and IIRR he ground the hammer down to get the ctg in.

[marlinman93]

The maximum length has more than just length to consider. Rim and base diameter come into play also. A smaller rim and base diameter will clear the breech block easier, and allow longer length.
But the block contour also affects what length and base diameter the Rolling Block will accept. So if your donor rifle has one of the concave breech blocks machined to clearance larger rim and base diameters, then it will accept longer, and larger cases.
Which breech block does yours have? The flat block, or the concave?

I want to take one of these RB and I'm looking at maybe a 40-82, or something in that realm. Only using BP and cast.

[wwmartin]

I've had no problems with my Green Mountain barrel and chambered in 40-82WCF on a #5 smokeless receiver.

[kootne]

I think you will be fine with a 40/82 and the rifle you showed in the photo. The hammer appears lower than what I am used to on sporters. The tapered case will very much work in your favor. I'll try to attach a couple photos of a 40/70 2-1/4 (COAL=2.8) for reference. Your case and bullet will be longer but you will see the idea.264635264636
There is a lot of clearance in this case.

[wwmartin]

40-90-2 5/8 bottle neck will also clear the hammer and block.
WW

[sharps4590]

A roller will not chamber the 45-120 without modification to the hammer nose AND taking some brass off one side of the rim. At least the Pedersoli I had the chamber cut for the 120 wouldn't. I had the barrel set back and re-chambered to 45-70, then sold it.

[M-Tecs]

As stated by some the RB does have AOL issues with longer cartridges. This is strictly from memory and I am not a RB guy but I believe 45-90 is about the limits without having to modify the hammer nose.

Well you guys have come through for me once again. I have not yet found out which # action within the Remington group that the Swedish government decided to license from Remington to manufacture their military arms. I need to drop dutchman a pm maybe there is a way to find out which model Remington action they used.

I thought I read somewhere that the 44-77 was the longest that would fit. So I figured this would be the right place to ask.

[ascast]

It may depend ion which rollers action you have. I had a Navy Arms in 45-70 once and had to trim the face off the hammer a tad to get really heavy pills into it. Ken Waters discussed this a bit IIRC. Bullet selection plays a role as well. Shorty's work, but that Lyman 462560 won't go. Too much nose. Great shooting bullet. Hope that helps a bit. There are limits at least in that gun/action/caliber. My original 7mm seems to take anything. My Danish (?) in pseudo 47-70 seems to take about anything, but I not loaded a full spectrum of bullets as the twist is about 1 in 36. I got a kick out of some of your responses. I can't speak to all rollers, but the Navy arms in 45-70 does have limits.

[MOA]

M-Tecs, if the 45-90 would work, than it's likely the Winchester 405 would be a good candidate too, be it loaded with black and cast

[Gewehr-Guy]

I would assume that all the Swedish rifles used the # 1 action on all their models, so if you can find an advertisment of Remington Rifles, I'm sure they offered the biggest cartridges that would fit, trying to keep pace with their main competition, the Sharps Rifle. I recall seeing a copy of correspondence from the Freund gun shop inquiring about a rifle in .50 cal, and Remington replied that they only offered in .50-70, because of a safety issue? or maybe a longer .50 just would not fit?

[M-Tecs]

As I stated I have limited knowledge of RB's. Not sure how the longer bullets chamber in a 45-90.

They do make them.

Swamp, that is one sweet looking RB. What are you shooting for cast?

[swamp]

I have a Hoch 650gr. and the Lyman 515141 for light loads. It has a 30 inch 1 1/8 barrel. It is not a woods rifle.

[marlinman93]

Bottleneck cartridges like the .44-77 SBN make it even easier to chamber since the bottleneck allows the cartridge to enter the chamber at an angle. It's the long, straight wall, large diameter cases that create issues. The .40-82 might be one that wont give a problem based on the smaller .40 caliber neck allowing for angled entry to the chamber. Doubt you'll even need to clearance the hammer.

[MOA]

Well I kept thinking all night where I put that bag I just got from slam45 that had a few new Jamison 405 Winchester cases. So started digging around and came up with it after only 30 minutes. Absolutely no problem getting it to enter the chamber.....tho the existing chamber mouth is a bit larger than the 405 would be since it is still chambered for 8x58RD. Things are looking up. May just have another toy going off to JES for a change over.

[RustyReel]

Just curious, what do you think JES can rebore an 8x58RD to?? Fairly wide base on the 8x58RD and fairly thin barrel at the muzzle. Just wondering. I think the 8x58's make dandy little sporters as they are but something on the same platform punching a little bigger hole would be nice. Keep us posted on the JES thing. Thanks.

[John Boy]

Does anybody know the maximum length cartridge that a rolling block will allow to be chambered.
Depends on the nose ogive of the bullet and how far out seated into the case. There are bore riding bullets that will fit into the leading bore cuts and others like the 457124 and 457125 with fat ogives that are SAMMI overall length (OAL) dependent
Best recommendation: Buy a Lyman #4 Reloading Manual - choose the bullet you plan to shoot and it will identify the OAL for that bullet. And be sure to reload one round and test that in your rifle before reloading them all

RR, from what I've looked at so far, the following measurements are as follows.
1. This would be a BP shooter.
2. Existing donor is a swede roller currently chambered for the 8x58RD
3. This is a case hardened action for shooting the EARLY smokeless powders so no issues shooting BP in it.
4. Basic measurements for the 8x58RD. Rim: .579. Rim thickness: .063 Base dia: .505.
5. Basic measurements for the 45x110. Rim: .608 Rim thickness: .070 Base dia: .505
Looks to me that any basic 45-90, 45-110, reamer would clean up all of the old chamber and rim, with the barrel rebored to .458 or .459 and shortened only enough to provide the needed wall thickness and recrowned it would seem a 45-90 or 45-110 would be feasible. Something to run by Jesse for sure though. I suppose one could drill and sleeve the chamber for something like the 40-82 winny with the rebore to .410, and shoot only black might be possible and less expensive than new barrel and all that is entailed with that. Good food for thought.

Makes sense if you are going to shorten the barrel a bit. I kinda did a back of the envelope type thing looking into what would work without shortening the barrel and keeping the sights that come on the sporter version. My muzzle measured about .62 so a 40 was about as large as I could go. I couldn't find any reasonable available 40 that would clean up the 8x58 chamber. My thought was to buy one of the poor bore rolling blocks they list from time to time and have it freshened up to a 40 something. Never really thought about shortening the barrel....should work.

[marlinman93]

One could bore the chamber on the 8x58 and then sleeve it down first. Then bore out the rifling and re-rifle it to the .40 caliber. Then simply ream the chamber to the new case you want. Saves setting back the barrel, and saves money for the cost of setting it back and threading, headspacing it again. Not to mention reworking the forearm, etc. to allow for barrel setback.

[koger]

Having just gotten into shooting a 8x58RD, Why would one want to change it, if the bore is good. Mine is very accurate, and has no bad habits as of yet. I have not even started to load J words but will be giving it a go soon.

That's what I was thinking if I was to go with the 40 and using this roller, just was not sure if it was a do-a-ble procedure cause I do not know a thing about gunsmithing.

Ahhhhhh koger, that's cause you haven't been bit by the hugebattery bug yet. If I can have three or four of these inexpensive rollers and have some made into other calibers that interest me at a great price and not a lot of time to do it, well, that's what I do. I already have one in that caliber, and I don't plan on changing it. I would like to get two or three more of same caliber and then have them rechambered into........oh maybe a 40-82, a 45-90, or maybe the 405 Jes. all for just a few bucks.

[Jedman]

I have a Swedish rolling block shotgun in 24 ga. and it has a action very similar to the Remington no. 1 1/2 in size and shape which is a very nice size. The 24 ga. shot shells are as large in diameter as most any centerfire cartridge you would use and the length would not matter I don’t believe.
They fit very closely over the breech block.

Contact John Taylor here and ask him if he thinks it's doable. He's done chamber sleeving before, and could tell you if yours is one that could be done.

[koger]

MOA, you are wrong my friend, I have been bitten by the singleshot/bigbore bug very badly. I currently have 14 of them, from8x58R. 38/55, 45/70, 50/70, 12.7x33R. I am selling off a large part of my collection, to further advance my addiction.

[country gent]

Dia of the cartridge also has a bearing on the length a larger dia will need to be shorter. A 45 2.4 may be the longest 45 wit a 38 cal may be able to be 2.6 or 2.8 long as the smaller dia rim will clear easier.

Was just looking over their site. Saw nothing offered in 40 with octagon barrel. Only round. If I have to replace a barrel on a roller I sure as heck won't be spending that kind of money an end up with a round one. So most likely GM won't be getting my money on a 40 barrel.

They still list a lot of .40 cal. octagon barrels. They're under BPCR tapered octagon barrels. I've bought numerous .40 and .45 caliber tapered octagon from GM.

http://www.gmriflebarrel.com/classic-tapered-octagon-rifle-barrels-4140-steel/?sort=featured&page=2

The .40-65 barrels shown are 1:16" twist, and .40-82 barrels are 1:14" twist. I'd probably go for the faster twist 1:14" twist, which will allow you to try even heavier bullets if you want too. But they're also about $45 cheaper. A #4 weight 14" twist 35" length is $325.

[RustyReel]

I did the math on those a year or so ago. I don't have the skills or the tools to install one of these myself so once someone else installs it I would have over $800 in a surplus military rifle with a new barrel, still needing sights and finishing. New stocks push the price way up. Makes the used Pedersoli I passed up for a grand look like a real bargain.

A rebore of one of the Swedes would be something I would consider if it were a simple rebore. As things are, I'm quite happy shootin' them as 8 and 12.7 mm's.

[marlinman93]

It's pretty easy to get $1200 tied up in building a Rolling Block from a donor rifle. But much less than any other action a guy could build from. Most others could cost you that amount, or close to it just for the action alone!
I still prefer using old military actions, and building exactly what I want vs. buying a new made Pedersoli. Nothing at all against the Pedersoli rifles, as they're great guns. I just like using old actions, and being able to choose my caliber and barrel weight and length. Plus I find donor actions occasionally around $100-$200, and sometimes even less. So hat's enough incentive to build another.

[MOA]

I think I'll probably send three 8x58RD to Jessse. One to be bored and chambered to 45-110, another bored and chambered to 405 Winchester, and the last bored and chambered to 40 krag. Now that should keep me busy and off the streets for a while.:bigsmyl2:

Hope there's enough barrel diameter to bore to .45 caliber!

Hope there's enough barrel diameter to bore to .45 caliber!

Well, me too. I think there should be. These have over 30" barrels in most cases so if I have to shorten them by a few inches to get into more barrel diameter it will most likely be ok. If not, then I'll start to make other plans on calibers.

[RustyReel]

Just saw a Swede listed on GB that claims to be in 32-40. Kinda looks like the barrel had been set back but I'm not certain. I'm guessing that isn't an inexpensive option either??
