does anyone have any idea what a duplication for prvi 285 grn sp load would be.i bought a couple boxes of ammo to shoot up for brass,as well as 100 prvi 285 gr sp boolits.man are these boolits ugly,but they shoot well.i am getting 3/4 inch groups at 100.i don't know how they are going to perform on deer but i am hoping to try.i would like to load with either 4064 or 4350 ,4064 is kinda my go-to powder.any help would be appreciated,thanks adker.
