I recently aquired a Remington 660 in 6mm rem. It has a 20" barrel, 1:9 twist. I will primarily be using it to hunt whitetail deer. I already have another rifle in 6mm rem, a Rem 700 varmint special with a 24" heavy barrel that I load 60 gr hollow points for.

I realize I'm losing a good bit of velocity with the 20" tube, but its such a handy little carry rifle that I dont mind. I want to load at least 80 gr or heavier for it. I like the 80 gr Speer deepcurls but they are too scarce right now. I've also considered the 85 gr partition. I'm not opposed to going as heavy as 100-105 gr if they shoot best in my rifle.

My question is, does a short barrel rifle like different powders and weights than a longer barrel? If so what kind of powder and what bullet weights would be better for the shorter barrel?

I have heard ball powders like Win 760 and similar, and heavier bullets are better for short barreled 6mm's. But I've HEARD alot of things that don't always turn out to be true.
