I bought a 550B years ago and was completely satisfied with it and the company.I'm retired now and thinking more and more of getting back to reloading.
I believe the " new green " bullet going to our troops is bonded.Supposed to be a big step up from what they have now.If it turns out to be a good light armor piercing bullet look for some changes/restrictions back home as far as " bonded " goes.
I have a Perfomance Ctr 627-5 with a 5 inch barrel and a 686-6 with a 4 inch.Why does the 686 have more recoil shooting the same round ? 1 inch difference in the length can't make that much difference.
