I shot 2 WW2 K 98s one a mix master with various parts I found and put together

the other is a Polish 98/48 put together after the war,  I think neither were bedded or tuned.

both hated IMR 4064 with 44g and a Nolser 200 gr match bullet OAL 3.225 brass was new PRVI Winchester primers

doing a ladder 45 gr was better and  looks like the sweet spot.  46 and 47 gr enlarged the groups slightly and also  increase recoil

bests groups with the 45 gr load were at 1.5 inches at 80 yard for both rifles.

My old eyes made the target fuzzy

shots were fired off bags temperature was about 90 degrees, light  cross wind

I wanted to see which was a candidate for a replica sniper .  The Polish had the best groups and stayed on target after it got hot.

any one else have a pet load for the 8X57?  Thanks

200 grain SMK, PPU brass, 48 grains of IMR 4350, and COL of 3.10.

I load 52.0 grains of IMR-4350 with Remington brass and Remington 9.5 primers with Sierra 175 grain Pro-Hunter bullets.

1.25" groups at 100 yards from my Remington 700 Classic. I use Sierra's published OAL.

I think Varget, Re-15 and VihtaVuori N150 would work well too.

I happened to have a quantity of IMR 4064 on hand

I read on the net that 47 gr of Target and a 200 works as well

It had a little sticky bolt lift on my mix master

41grs Tac and 200gr SMK or the Nosler CC. Both shot real well.

I have had very good results with Sierra Game Kings in 150gr using 4064 out of an Ankara.  I'll have to look up the charge later but I've shot 1" groups at 200 yards with it.  Also probably the most devestating load I've used on deer.
