You will probably notice that RKS gain twist barrels will reduce chamber pressures a wee bit. I think that is because the bullet is not instantly trying to accelerate forward and spin 180,000 rpm or better in the same millisecond or so after ignition.. I also think they are less stressful on some bullet jackets... especially if the bullet does'nt engage the lands perfectly. The very slow initial twist rate allows some xtra time for them to stabilize before they really get to spinning. At least those are my thoughts on gain twist. There's no downside to progressive twist at all , that I have experienced.
I have four of Rons GT barrels and they are all superbly accurate in calibers from 6.5 to .35 Whelen.
