I must admit the heaviest .224 bullet I shoot is 60 grains. When reaching beyond 400 yards I like 100 grain .257 bullets that go 3800 fps from my 257 STW. The .224 bullets just don't have the wind bucking capabilities and retained energy as does the much heavier 257 bullet. I also have a 6mmX284 and with 75 grain bullets it is not much better than the swift beyond 400 yards because I cannot drive the bullet much over 3600 and not making that magic 3800 fps hurts its performance much beyond 400 yards. Don't get me wrong all of them will kill a coyote stone dead at 800 yards and even beyond if you can hit him. Key words "if you can hit him" which from my experience one stands a much better chance beyond 400 yards with a fast .257 100 grain bullet than any .224 bullet.
I have a 7mm STW but I am not familiar with the 257 STW. What case is it based on?
