I shoot a 525 grain bullet that I cast from an RCBS mold in my Knight 50 caliber MK-85. The bullet is devastating on deer. And also very deadly on elk. I shot a large New Mexico 5X5 with the bullet. It worked tremendously.

I cast it from lead I was given that was taken out of Church windows. So I call it Holy lead. I would tell you how many grains of 3F BP I load but you would call me nuts. But needless to say the recoil is extreme. I have torn and bloodied my thumb webbing several times with the load. Tom.
