I shoot the sm 42 gr. calhoun bullets in my 221 and the same in 50 gr. out of my 223. They work perfect on coyote for me. The problem is I can only find them at cabelas. I am getting started in reloading and do not have any idea on what powder or velocity hsm is getting. The calhoun bullets really work great for me so I would like to sick with those. Any info would be great.
