Load data for 30-40 and 210 #311284

[clearwater]

Noticed the thread about someones classic 30-40 krag Ross blown up when using a max load of 5744 and a 210 grain boolit.

I was just going to try some loads with that boolit. The lyman 49 lists that same
load as most accurate.

I have 5744, but also 2400, unique, trail boss and some slow stuff.

Gun is a rechambered handi rifle. When loading the rifle, the cartridge will be pointed down being a break action, so powder would often be up toward the boolit.

Should I try the 5744, or is there a better powder (maybe safer) to try first?

Before my rifle blew up, I was getting really good accuracy out of 40 grains of IMR 4350 with a 200 grainer. I got that data from this page, which is worth a look. Good luck.

Clearwater,
I don't know about blow ups but I shoot alot of #311284 over 20.5grAA5744. I don't kown FPS and only shoot this at 100yds. Out of my '98Krag sporter I can get about 2 1/2" and well under 1" out of Ruger No3 30/40....WW and GC sized to .311dia....HTH...Tedly

I'm using 38.5 gr. IMR4350 under the Lee 309-200-1R (sized to .310) in my '98 Krag Sporter which yield 2"-3" (iron sight) groups @ 100M.

24.0 gr 5744 + dacron, 200 gr cast= 1740 fps
39.0 gr 7383+ dacron, 200 gr= 2021 fps hunting load

I don't know about rechambered Handi-rifles, but I am always leery about trying to make something into another thing for which it was not designed.

I also has no experience with 5744 or Trailboss, although both get good press as cast bullet powders.

I do have lots of experience with the 30-40 round, 311284 and 2400 in Krag and Winchester 95 rifles. 16/2400/311284 is a good accurate load in any rifle safe to fire factory 30-40 rounds. When pressures start to exceed what is needed to push the bullet past 1.7K fps, then slower powders are needed.

The best load I have found for that bullet in the 30-40 at 2K fps is 50/WC872.

Best of luck with this great round.. Charles Graff

I have also had very good luck with 50ish grains of WC872 & WC860 with 311284 in a 1896 Krag rifle.

Have Fun

The rifle is a modern sb2 barrel and frame, so should be able to handle 30-40 published loads fine, since the other barrels for it are 444, 308 etc.

It shoots 170 grain cast with 18 g 2400 really well. I do have IMR 4350.

This gun with 220 J bullets and one grain below max load of Reloder 19 shoots into the same 1" bull at 50 yards as the 170g.
Velocity is 2100 fps while the 170g cast load is a very consistent 1700 fps.

Looking for a deer load for the 210g boolit in place of the J bullet.

Anyone know what manuals to look at to double check these loads for the 4350?

I will try the 2400 too.

Thanks

Clearwater; my Krag has a 24 inch barrel, with 200 gr Lee cast I get

2400-18.0 gr-1550,19.0 gr-1630, 20.0gr-1665fps

WC 872(slow lot#48772 Pats) 50=1690
51=1754
52=1796
53=1798 fps

WC872(fast lot #49617 Bartletts) 51=1879
52=1906
53=1940fps
All 872 loads use cci#250 primers, as you can see lots of this powder can vary much.

23.0grs H4198 + dacron under the 311284 is my favorite load in my Krag.

I'm getting good results with 20.5 & 21 grs of 5744 & a pp'ed lee 200 gr in my 30-40 Krag highwall (uberti), holds right around 1 in at 100 yds if I do my part. This is with a cci l/r primer. I have noticed almost no unburnt powder in the bbl with this load. One wet & one dry patch is all I need to clean.

Mine is similar -

Excellent load in my 25" bbl'd Krag sporter. Charles put me onto that load several years ago, and it is a very good load.

Have a look at Hodgdon's on-line load data. It has load data for the Krag for 200gr and 220gr j-words.

Here's the link.

Pardon me for jumping into this thread, but could you tell me about that peep setup on your Krag?

[Char-Gar]

I am not Buckshot, but I can tell you about that Krag receiver sight. It is a no drill and tap Redfield. It attaches via large sideplate rear screw and a clamp and screw that fits into the magazine cut off. Redfield made these is the micro-click adjustable version (shown) and a non-click adjustable Model 102.

They are good sturdy sights that can be used on the Krag without drilling, tapping or removing any wood. They appear from time to time on Ebay, but are getting quite pricey.

Hijacking this thread even further, for which I apologize but:

Are you sure? Help me, cause I have a sight that uses the magazine cut-off slot and with the nice sight in the photo it looks like the cut-off is still there. On mine you have to remove the magazine cut-off and slide a post that holds the the sight into the hole for the cut-off.....

Thanks,

Mark

[Char-Gar]

I am quite certain, that is the Redfield mentioned above. I have several of them on Krags. I remove the magazine cutoff. But, in all truth, I have never tried to put it back. I think you would have to do a little filing on the cutoff to get it back in.

If you look at Buckshots pic, it has been replaced AFTER the clamp and screw that attaches the sight have been installed. It most certainly would be non-functional as it could not be rotated down without hitting the sight attachment screw. If you look at the pic, there is a clamp and screw on the rear of the sight. There is a lip on the clamp that fits down into the magazine cutoff hole a shot distance, There is another lip on the other side of the clamp that fits into a groove in the receiver sight base. The cutoff hole itself remains largely clear.

I suspect that Buckshot reinstalled the cutoff not for function, but to keep from loosing it. But we will need to hear from him about that. He is a crackerjack machinist and might have worked some magic on the cutoff.

There is an old Pacific sight for the Krag that attaches via a rod that slides into the magazine cutoff hole. I have one of those also, and suspect that is what you are using. With that sight, there is no way, the cutoff could be reinserted. These sights are marked "Pacific" on the rear of the base, next to where it butts against the receiver.

[Mark Daiute]

Char-Gar, you nailed it. And I noticed that the cut-off would not be workable but I figured there must be some clearance there and that I was misinterpreting what was there! Thanks.

[Buckshot]

...............Char-Gar nailed it. Best place to keep the cutoff IMHO

That looks a lot like my sporter Krag. It's got an old set of Lyman sights on it.
