Buy some, shoot it in your rifle, and you tell us. All rifles will shoot different types of ammunition to different degrees of accuracy. There is only one way to find out what will work best in your rifle.
I suggest you buy a single box of as many types of ammunition as you can find and grade them for accuracy in your rifles. Its the only way to truly know

 

I largely agree with the above.

I've tried the stuff in a couple of my rifles, and in them it printed to a similar POI as Extra (much higher than lighter bullets at shorter distances, i.e. 100-200 meters). Groups not nearly as tight as Extra, though.

 

It's hunting ammo. It's fairly accurate over distance. I still have a box of it somewhere if I ever go boar hunting.

 

OK Here is a rule of thumb to begin with. It has been my experience that Brown Bear/ Silver Bear have a .310 diameter 203 grain bullet. Russian LVE ammo is the same .310 This ammo works very well in Finnish M39 rifles which usually have a .310 bore and Tikka 91/30's which many are slugged at .3095. Russian Mosin Nagants generally have a larger bore than this so I would use Sellier & Bellot 7.62x54R ammo which I have found has a .311 plus bullet in these rifles. If you are hunting with a Finnish M28/30 or a M28/76 rifle many have .308 bores and the Sako and Lapua commercially marked 7.62x53R ammo is loaded with .308 bullets. Every Mosin is different and you should always slug the bore for optimal performance.

 

Vortrekker gets down to it. Slug your bore. Mosin standard is supposed to be .310, but many rifles do better with a slightly bigger diameter.

That said, I have tried Brown Bear softpoint in a very accurate 43 Tula sniper and found that, for hunting ammo it would be OK but for real accuracy of "sniper grade," it can't do it. I assume you plan to hunt with it, so just go to the range and start shooting, marking your results. Will it do what you need to hunting range, 100-200 yards? Almost certainly, sighted in right.

Remember, hunting shots are almost always what is called "Clean Cold Barrel" in accuracy testing, so try it the way you would shoot it. One shot, cold barrel. Then wait, cool it off, second shot.

No softpoint I have tried comes close to top Match or Extra, to my best old Novosibirsk 188 or to new LVE light ball at 100 to 500 yards. If you handload, you have all sorts of possibilities.

The various softpoints just don't have the shape and ballistic coefficient to really get MOA accuracy out of a Mosin, but a 2-3 MOA is just fine for any normal hunting. The famed "minute of pie plate" accuracy at 100 yards has put down many a deer!

It's been a long time since I used the stuff but Brown Bear is or at least was lacquer coated, and gave me sticky bolt syndrome in short order.

 

Those 203 grain soft points do kick like an angry mule. Always shot fairly well for me.

 

I love the 203g BB stuff in my carbines. 91/30 M91? Meh.

I still have a few hundred rounds of the Barnaul stuff. $2.03 per 20. Don't think you can find that any more.

 

I have had good results in my Sako M39. Big medicine on hogs.
