View Full Version : Will this shoot?

I have a Mosin M44 whose bore I have slugged. I mic'ed groove to groove at .315".
The rifleing is strong, with a fair bit of throat errosion.

The closest bullet I can cast is a 186 grain .313 gas checked bullet from a lee mold which I can then size at .313" in my lubrisizer.

One of these pushed into the bore shows a clear and fairly deep rifling imprint
but clearly the wideest dimension of the bullet never even touches the bore.

I'll try it, but I have no high hopes. Is there any chance this will shoot decently?
I was wondering if a higher end charge of rapid powder (red dot maybe?) would upset the bullet enough to seal well.

I am looking for 100 yard accuracy for target and plinking, maybe some small game and wood chuck hunting next summer.

I had the same problem with a 38-55 winchester M94. The groove dia. was .379 and the bullets were only .376. I found out that using soft bullets; wheel weights plus 2% tin, not heat treated, pushed faster. They slugged up to fit the bore and I got good accuracy at 100 yards with iron sights. The bullet sizing die I had was .376 also, so it was only lubing the bullet.

I had been trying to shoot hard heat treated bullets, but they would not fill the bore.

You did not mention what alloy you were using.

I shoot wheel weight with some extra tin added by way of 60/40 solder.
Both air dropped and water dropped. These .313" bullets I have always
water dropped, but I think I will try air dropping for this.

I am also wondering..... perhaps I will try them without the gas check as well.

If you've got any soft(er) lead, like the stick-on wheelweights, I'd add some of that. I'd also leave the gas check on and if I had a larger sizer, I'd put the gas check on and lube with it. You could also try to build up the size a little with Lee Liquid earwax. Regards, Woody

Beagle it, the mold that is.

I had an M-N , M44, .315 groove, did all I could to fit it, even reamed a mold out to .317" and made a sizing die to fit, still got 2 1/2" groups at 25 yds. I solved the problem by finding a pawn shop that would buy it.

I have heard of some using the dacron fillers in these cases. They claim they help seal the bore to help them shoot better taking up those few thousands extra space! I have a rifle I've been meaning to try it on. A spanish mauser with an oversized bore of .290. Even jacked bullets shoot bad in it!

Carteach,

Have you thought of "patching" the boolit larger with teflon tape? I'm not sure if it would work, but I have read of guys wrapping teflon tape (plumbers tape) around boolits. I don't remember the logic behind it, if it was for improved fit or lubrication, but it may be worth a shot.

You could try lyman's 311299(314299?). Mine casts .315+ and may do better than Lee's mold.

A friend of mine has the same problem with his nagant,so we cast bullets out of 50/50 ww and lead and loaded them and it worked. 311299 with 25grns off 2207(4198) dacron filler water quenched 2'' groups at 100. worth a try!! Pat

Dunno where I was when I posted my answer. Brain fart I guess! Beagling is prob'ly the first thing I'd try and a couple thous. is very doable. I've never done the teflon tape thing but have paper patched boolits for a big bored krag before I had a mould big enough. It worked well, but is a log of work. Regards, Woody

............Does this mean it's time for another FAT 'Fat 30' GB :-)?

If someone is going to start a Fat-Fat-30-GB project, I would like to purchase one of those molds.

By the way, what does GB mean?

I would be interested in a fat 30 group buy for my larger bore mosin's.

I had the same problem with needing bigger bullets for my smellies. There is a lyman mould to met my specs but it is (I believe) discontinued 314299 a bigger heavier bullet about 200 gr, is very hard to find, high demand, and accordingly, COSTY

Check this out:

I use a Lee 311-155-2R which casts big, some as big as .313, and with a scoop of antimony in my tin-augmented wheelweight metal makes BIGGER bullets when cooled, many of which go up to .315

try it out before risking a mould thru beagling. then if my trick doesnt work, you can grind away in good conscience

Yodar,
there is no "grinding" involved in beagling a mold and it is completely reversible.

perhaps a reading of the technique again may be in order....

Absolutely correct! I have "Beagled" several moulds with good results, including multiple cavity mopulds. If you are grinding..you ain't Beagling.....you are just grinding.
