Hi Guys, Just about to start loading for the above cartridge using N140 powder, nny 54r cases and PPU 174 gr FMJBT bullets. Looked in various books and at the Laupa site. The closest I can get is for a 170gr bullet. The general consensus seems to be start at 43.5gr and max of 46.9. Does that sound about right?
Also I have some 7.62 x 53R cases. Would it be alright to use them in my Mosin?
Thanks

The Lapua bras is actually 7.62x53R.
Yes 7.62x53R is fine to use in the Mosin.
