Loaded 243 for my stepson, used regular 90 grain boat tails and 4350 for powder. He was a little on the cheap side or I should say his wife was. He had a Rem 600 Mohawk and it shot that load real well so he used it for everything, fox, yote and deer, but I think he had to learn to sew a little. Guns are like a woman, you have to play with it until you find that G-spot then your good to go. I take it that you reload so play with it, you will find what works for you. Back in the mid 70's I used a 22-250 for fox and I loaded down to like 3000 ft per sec with a 55 grain blunt nose steel jacket. 4895 powder and it would leave a pencil hole in and out if you didn't hit a lot of bone and it fit my rifle well even out to 300 to 400 yards. You just learned what it would do if you shot it enough.
