well the name of the thread says it all, does anyone have a decent load worked up for mosin snipers ? i dont need a specific "end all be all load" but if someone could shove me in the right direction that would be awesome!

bullet weights, powder, primers, something that i can feed this girl and hit some water melons at 300 yards!
 
Mine loves 45.5gr of Varget with a WLR primer and 150gr Sierra SP. Averaging MOA with this load, my smallest 5 shot group to date is .65" @ 100yds. This load is safe in my rifle, you need to work up to this load for your rifle though.

Try 38 grains of 4895 with a 180 Sierra flatbase Pro-Hunter bullet. Seat to the OAL of a Ball round.

We had excellent results with this load here in 5-year test series on 3 MN rifles.

One thing we did settle was bullet diameter: EVERY MN we tested shot MUCH better with a .312 bullet, very well with a .311. Ordinary .308 slugs are hopeless.

This is also a very accurate load in a .303 and it is NOT high-pressure at all.
 
hey smellie would slugging the barrel too get the proper diameter be recommended, from what i can tell this thing may never have been fired
 
I think you would be pretty safe just running .311 slugs through it, then trying .312 and see if there is any improvement.

I pulled down some original Soviet-era Ball ammo a number of years ago.

Slugs were .311... but they had a MINIE base!

TBSA - 1909 gives .308 for the bullet diameter, but that was with a 214-grain flatbase and a heavy charge of Pyroxilline: the bullet WOULD have upset, most definitely.

Essential to accuracy, no matter what the rifle, is one condition: the Bullet must FILL THE BORE. Anything else and you have blow-by and blow-by is guaranteed to play the devil with accurate shooting.

Hope this helps.
 
You have to work up the load for your rifle. I've always found that starting with the powder used for the accuracy load in my old Lyman manual works well. I'm not at home, so I can't look. I'll try to remember and post it Friday. I think there's a manufacturer who makes a .311" match bullet. Forget who, of course.
"...Ordinary .308 slugs are hopeless..." Comes from .308" being the wrong bullet diameter. .308" bullets don't work in .303 British rifles either. Mosin's at least don't have the Lee-Enfield barrel diameter curse.
 
I slugged both mosins and my SVT, they came out at .3105, .311 & .312 - definitely go with a .311 bullet. I used 150g SP loaded to 2600 fps [by the hornady data, not sure what the charge was] the results were not encouraging in any gun. Moving to a 174g fmj next... if that helps at all.
 
Be sure to stay with the FLAT based bullets, friend. Try the boat-tails AFTER you get it really shooting, if you must.

174 Match slugs all seem to be boat-tailed base: blow-by is guaranteed.

Try the Sierra 180 Pro-Hunter. It is a .311 but it is also a flat-base and it is soft enough that, if you smack it hard on its little arse, it WILL upset.

Hornady makes a .312" 174-grain flatbase, but it is a ROUND-nose.

Hope this helps.
 
I remembered and found this post. My Lyman book gives IMR4350 for all bullet weights between 150 and 220. I'd use the Sierra match kings using 180 grain data.
