In my experience, the Mosins tend to favor the heavier ball over light ball.


December 8, 2006, 09:37 PM
Mosins seem to be picky about ammo. The best thing to do is try several different "brands" and bullet weights to see what yours likes best.


December 8, 2006, 10:38 PM
My 91/30 and M44 like Czech 147 grain, my M39 likes the 174 and 180 grain.

December 8, 2006, 10:44 PM
My M44 seems to like Czech light ball.
Granted it will fire anything resembling 7.62x54R. The best fireballs seem to come from the old heavy ball. Something around 50's production in the 174gr variety should do it.

My M44 seems to prefer 147 gr light ball. My shoulder prefers me to shoot light ball in my M44.

My M39 and my M28s shoot well with either. I haven't been able to determine if heavy or light ball shoots better. They both seem about the same.

December 8, 2006, 11:04 PM
Mine all so far favor the lighter ball.

December 9, 2006, 01:44 AM
I only have a silver tip version of

and locks up my damn bolt practically all the time....

I got many recommendations, people say it is due to laqured ammo. So I will basically use
a 12 gage wirebrush and clean the chamber.
I will also grease the bolt instead of light gun oil as I was doing before... will see what happens.

I shot 50 yards small scale targets with that thing, the gun is much better than my skill.

December 9, 2006, 02:22 AM
curently i shoot the light ball but i see some comercial 180gr on aimssurplus at a good price so i was just wondering. My 91/30 shoots a little high with the 147gr at 75 yards but that is expected, lets just say the rifle is better than me.

December 9, 2006, 09:01 AM
Most of my mosins do very well with the Czech light ball. A number of my Finnish mosins however like the heavy ball (Hungarian).

December 9, 2006, 10:08 AM
The M38 likes the Polish stuff best, and the 91/30 likes the Silvertip stuff, when it comes down to surplus, but I get FAR better results with the 91/30 with Hornady 150gr SP .312 loaded over 39gr of H4895...

December 9, 2006, 02:17 PM
I have been putting Silver Bear ammo though mine and shooting decent groups at 100 yards. I just got some new dies and brass for 7.62x54 and loaded some test loads with 180 grain ammo using 2 different powders. I am also going to try some 150 grain bullets to see if they do any better. I am going to try and get out tomorrow if the weather is nice.
Here is a 100 yard 5 shot group with the Silver Bear 180 grain.

December 9, 2006, 02:25 PM
Very nice - you should do fantastic with handloads!

December 9, 2006, 03:55 PM
not trying to steal this thread but when yall mean your rifles dont like certain ammo what does that mean exactly? does it mean it wont fire it or just not accurately or caus eothe rproblem? sorry just trying to understand it.

December 9, 2006, 04:19 PM
Mosins in particular tend to do best with a particular weight. I've had M-39's that shoot best with 200 grain loads and M-44's that really like light ball. When you have a new Mosin, the best thing to do after basic accurizing is bring an array of loads and test fire to see what the rifle likes. You can then sight in for that load.

December 9, 2006, 06:00 PM
darkknight, you had it right with "just not accurately."

December 9, 2006, 06:35 PM
didnt know it came in different loads all ive seen commercial is 185gr and the surplus i bought are wrapped in wax paper or something just assumed they were 185gr since its all ive seen

December 9, 2006, 08:29 PM
there is alot more than that, i seen as low in weight as 147gr, and as high up as 200, or 203 gr, wich is why we are talking about what the rifles like best. The general concensus at the time is, it varies from rifle to rifle.

December 9, 2006, 08:34 PM
i have a Mosin-Nagant M.1891/1930 and a M.1938. I shot the Czech silver tip, Hungarian ball, Russian sniper, ect my rifles like them all and they are just as accurate with any of them. I have even used some of that Silver Bear SP ammo, but mostly i shoot surplus and see no difference in one or the other

December 9, 2006, 09:33 PM
my 38 likes them all, including the 205 grainers.

December 10, 2006, 03:55 AM
Dont mean to highjack this thead but has anyone removed the wood around the barrel and noticed an accuracy improvemnt? I read that anything attached to the barrel disrupts the harmonics during firing, affecting accuracy. Snipers in WWI &WWII sometimes cut off all the wood attached to the barrel and modern high accuracy barrels are bare. I just bought an M38 and I was curious.

December 10, 2006, 11:36 AM
My PSL prefers the heavy ball from a reliability standpoint. Jury is still out on accuracy until I figure out the optic.

December 10, 2006, 02:45 PM
sh3rm4nt4nk, you don't need to denude the barrel to do that. The Finns used shims to lift the receiver and barrel up and float it. You can use scrap brass or aluminum to do the same yourself. Just stack them up until the barrel passes the dollar bill test.



There are also sporter stocks you can transfer the action over to, though they're pretty ugly.

December 10, 2006, 04:55 PM
Any other tips on accurizing, Cosmo?

December 10, 2006, 05:47 PM
Make sure the receiver screws are hand tight, clean the chamber as well as the bore. Pick one out with a good crown in the first place.

December 10, 2006, 06:19 PM
also put 1 or two toothed washers between the trigger lever and trigger. dont worry about the exact size, just make sure it is big enough to get around that bolt. this will take up about half the trigger pull distance, and weight. you may be able to get another washer onit as well, and still have the sear catch work. but just to make sure, if you get a second washer on and it catches when you cock it, try to bump fire it. If it goes ' click' then take that second washer out.
dont' do the bump fire test with a live round!

December 10, 2006, 08:20 PM
I have a 91/30 and a M44 and both shoot extremely accurate with 147gr. ammo. The carbine doesn't like the heavy stuff but the 91/30 will tolerate it better. I would rather shoot the stuff the gun was intended to shoot, the 147 gr military ammo. As said by other in the thread, the 147 gr Czech silver tip surplus from the early 60's shoots the best out of both the 91/30 and the M44. All I know is for $3 a box I can shoot all day for very little cash!! :D

December 10, 2006, 08:28 PM
can somebody show a picture of the crown or explain what a good crown looks like. and the second what is the dollar bill test? If you cant tell, i am brand new to rifles. i know handguns and a little bit about shotguns but on rifles im clueless. sorry to keep borrowing from this thread.

a noob

I'd like to know more about accurizing my m38 as well. The thing is too damn fun not to get tighter groups with.

December 10, 2006, 09:57 PM
The crown is the end of the bore where you can (hopefully) see the end of the lands. A damaged crown can have significant impact on accuracy. I'd suggest doing some forum searchs for more information.

December 11, 2006, 12:13 AM
darkknight, I'm not sure about how to do it on a Mosin - since they have an upper hand-guard - but the dollar-bill test as I understand is attempting to pass a dollar bill between the barrel and forearm to see if the barrel is free-floated.

December 11, 2006, 02:33 AM
You do it without the handguard on, then check to make sure the barrel is floating after reassembly by pushing it up and down. It should give a little tap each direction. The best are the M-28/30's which have a barrel sleeve, but most will float with enough work. You can clear out extra space in the interior of the stock if you have the right tools.

December 11, 2006, 02:32 PM
Thanks Cosmo! So you live on a firefly or what?:cool: I think thats shiny. Big fan of Serenity and Fireflies in general.
You said brass or aluminum washers. Is steel too hard or what?

January 1, 2007, 12:36 AM
My M38 has an upper handguard thats loose. There's no way to be sure that its not touching the barrel at any time. Unless I secure it with some dowel pins to the stock. Now that the mind is on it, I think I'll rotozip the stock and handguard with a sanding bit to clear the barrel and use little dowel pins to keep the handguard from shifting.

January 1, 2007, 12:41 AM
You said brass or aluminum washers. Is steel too hard or what?

I think so. Steel on steel isn't the best idea, since your receiver's metal and blue can get scratched up. With a softer metal any scratches or gouges will go the other direction.

January 1, 2007, 12:53 AM
I think I'm gonna try rotozip with a sanding bit, and dowels for the handguard.
