I started handloading this spring for this caliber. first two loadings were win. cases, H335 powder[44.5g],win. LR primers. Both were 225g bullets,one partition the other a ballisic tip. Both seem to shoot wonderfully. Am having a problem with the primers but thanks to the reloading site here have that problem taken care of! Just remember this is for my gun, so start at 2 or 2.5 lower and work your way up.!!!!! According to my book the max. is 48g.....Hope this helps. I also shoot the BLR. Its one heck of a gun....
