Think I may have posted this before, but if not here ya go.
Nice sunny day here so I did a photo op.
1942 Finnish Mosin M39b built on a 1897 Izzy receiver and bolt.
180gr Sierra ProHunters (.303Brit .311dia)
46gr IMR 4320
PRVI brass
CCI LR
COL 2.975" +or- .003
Shot off a sandbag, irons, 100 yards.
9 of 10 shots @ 2-3/16ths center to center. Odd hole out was the very first shot.
Somebody gave me this recipie claiming it to be Sierra's accuracy load. It did pretty well, but I have since discovered this claim may not be correct. Sierra's current manual only shows loads for .308 rounds, and in the 180gr range the accuracy load lists at 53.5gr of IMR 4350.
Here are some pics.
