winchester 150 gr ballistic silver tips

[maiello]

My 300 wsm loves this factory ammo is there any way to find out what the load is winchester uses.

NO. Ammunition manufactures use powders that are not available to the reloading public.

If your rifle shoots that well with factory ammo just think what it can do if you start from scratch and tailor your own load.

you can do a lot to match a factory load, set your oal and crimp to match, primers will pobably be the same as you can buy. cronograph the factory rounds, then disassemble one. weigh the powder and with the visual inspection of the type of powder and weight, start reading reloading charts to match velocity and powder weight with powder type. with winchester ball powder in the case, that weighs 64gr at a velocity of 3175 you can nearly exactly duplicate this with w760. you might not know, winchester is using w760 but if your accuracy is good would you care
