How much Lead would a Mosin sling...?

There is a group but going on right now for a 316299, 200 grain spire point bullet. in the active group buy section. here is a link http://castboolits.gunloads.com/showthread.php?t=107545

I use Lyman's 314299 in mine.

[Nobade]

Mine likes SAECO #305, tumble lubed, loaded with IMR 7383 plus COW filler and no gas check. Shoots clean and amazingly accurate.

[Calamity Jake]

My mosin won't sling anything but it shoots 314299 pretty good.

[Larry Gibson]

I think you'll find 314299 to be a very, very good cast bullet in the MN. It has sufficient bullet weight, Most often a good fit and the GC/lube grooves will be inside the case necks. I also use in in MY MNs although there was Gb for a fat 311291 that also shoots very, very well in my MNs. The bullets drop at .315 - .316 and weight 190 gr. Cast soft of 50/50 alloy, HP'd to 1/3rd the nose length and loaded to 1900 - 2000 fps I expect them to deadly hunting rounds. Same sam with 314299 if it fits you MN bore.

They will handle 220 grains just fine and I am sure heavier since they are a 1/10" twist. You need to keep the bullet blunt if you go the limits on the high end. I use an Old West 220 grain (discontinued mould, I believe), and have used Lyman 311284 which is around 220 grains from my old mould.

There is a mould maker in Australlia whose name escapes me (maybe CBE?) and he makes heavy .303 British moulds. Some are north of 220 grains. If the nose is small enough to fit the bore in the throat of your barrel, they will work fine since the twist of the .303 and 7.62x54R are the same.

[Artful]

Check your bore as mine required .316 - some of the old solder's are a little loose.

[res45]

My M44 shoots the Lee TL .312 gas check bullet great,my mold drop the bullet on the fat side at .313.5 and I apply the gas check with the Lee .314 sizer.

With 16.0 grs. of 2400 it pretty much lays them all together in a nice tight cluster. My bore slugged just a hair under .312.

[Dutch4122]

I don't bother with slugging the bores on my Mosins because I have found that they are all over the place and you can go crazy matching sizing dies to different rifles.

Best method I have found to determine which boolit diameter to feed your Mosin is this:

-measure the inside of a fired and not yet resized case neck from a casing that has been fired in your rifle.

-subtract .001" from that measurement and that will be what you size your boolits to.

Example: if the inside of a fired case neck measures .315" then you will size your boolits to .314"

Hope this helps, :D

:Fire:
Dutch I am onboard, that is the way and I'll try to keep the bullets out of the same box- and check thickness of necks. KISS? I am bidding on a NOE 312284 copy of Lyman- 215gr RN, my reading says this is near what the rifle originally dispensed @2000fps. Have you tried .316-Boolits, in anything like .312 bores?
I'LL have a good day coming getting the Gal's out and showing them off- they really arent pretty. Everybody at least looks their direction, I guess four isn't a harem, I hope they're all girls!

Slowhand-

When you check neck thickness you will find that different brands of brass will be thinner or thicker. Best thing to do is to stick to one brand of brass. Then when you measure the inside of a case neck you'll know where to size the boolits to for each rifle. You are exactly right, KISS does apply here.

The boolit I would recommend is the NOE 316299; which I believe is currently the subject of a Group Buy in the Active Group Buys sub forum. This boolit not only casts @ .316" but also has a .305" bore riding nose. Another design that may be suitable in a Mosin with a shot out/washed out throat is the BRP 7.65 Argentine boolit. I have a 91/59 carbine that will chamber and nose engrave the BRP slug while no other design will. This will be test fired in the near future.

There is absolutely no worry when shooting .316" boolits through a .312" bore. The boolit will just swage down as it is pushed through the throat/bore. For example, all of my mosins (6 total) will chamber a .318" slug when seated in PRIVI brass. So I size to .317" and load. One of these guns has a .315" bore and the others I haven't bothered to slug. Two of these rifles are a pristine M39 Finn and a 1917 Remington (sporterized) which are well known for much tighter bores than the Russian/Soviet rifles. I have shot hundreds of these oversized slugs in my rifles with no problems and only one side affect - improved accuracy! On another note, I have a Spanish FR-8 Mauser in 7.62 Nato that has a .309" bore. I shoot a .314" sized NOE 316299 through this carbine with loads that are in the 45,000 - 48,000 PSI range with IMR-4007ssc powder. No pressure signs and accuracy better than my meager rifle skills can demonstrate.

In short, get a nice, fat boolit that will sit straight in the back end and nose engrave on the front end. You'll be very pleased with your results.

Hope this helps, :grin:

slowhand47, I enjoy your humour!

I make my own molds for my collection of 303 Brits. Each one has its own boolit and patch. Speaking of which ... [smilie=1:

Care to join us? Paper patching does have its drawbacks - it's addicting for a start. Then it raises your expectations and the end result is an insatiable drive to make your rifle perform better, then there is the realization that your rifle can perform better .... :mrgreen:

It's quite fun, actually.

I am hopeless at doing stuff for myself in my own time otherwise I would offer to make you a mold. I mean, I could try but I cannot promise. When I do get started I run out of time then don't get started again for so long and .... well, I'm an expert procrastinator too!:mrgreen:

Oh yes - I made a mold that casts 265gr boolits for my 303 Pig Gun (patched). 245gr smooth sided plain gas checked cast - worked pretty good too. (Or was that for my mint grooved rifle?)

[390ish]

My Lee 200 drops right at .314. Too wide for my Finnish rifles, but just right for the Ruskies.

[303Guy]

I intend to hunt wild hogs. It's really a bush/wet weather gun. Handy for the bush and it fits under my poncho in the rain. And its so light and easy to carry.

I never did range test the 265's. I'm sure I'll still have some. I'll have a look and measure them up for you.

[Three44s]

I like Dutch4122's approach here ...........

When the dust settled I ended up with five mosins and five mausers around here and the mere thought of 10 different sizes of boolits was scarring the bejesus out of me ........

KISS is definitely in order for me!

Thank you Matt, that's very helpful!!

You are more than welcome. If there's anything more I can do to help just send me a PM here at Cast Boolits.:-D

slowhand47-

I replied to your email. :D

[303Guy]

Thank you, slowhand47. I have been warned this past Sunday about feral boar's lack of sense of humour! Farm boars can have an attitude too. One of them killed a friends farmer uncle on his farm.

I had a jammed case in the chamber this Sunday with that Pig Gun! That will not do in a real life situation. I'm glad I tested the thing a bit.

On the Mosin subject, once upon a time the Lee Enfield was the longest serving military rifle but the Mosin has long beaten that record - and I don't have one!:(

Mine shoots 311284 HP'd, sized .314 real well over 2400 or with most of the slower powders.
