I am building a 6mmGT as a light, 18 inch barrelled rifle.
In my chosen contour/make of barrel, I can get a 1:8" twist easily and may have to wait a long time for a 1:7.5". I would prefer a 1:7.5" twist, but I am non-USA so parts availability is an issue.
I want to shoot the 108gr ELDM (actually 109gr ELDM but as I'm non-USA and they seem to be GAP exclusive, I'm shit out of luck -
@A10XRIFLE hook us internationals up)
If the 108 ELDM doesn't shoot in my barrel, it looks like a 105, 108, 109 Berger, 103 ELDX, etc will work as backup options with stability in a 1:8. I want good terminal performance hence my preference for the ELDM (I use these in .22 and 6.5mm with excellent effect)
I expect to get up to something in the range of 2750-2850FPS using Varget/H4350 and Alpha or Lapua brass (if it becomes available).
Has anyone got experience with a 1:8" 6mmGT and the 108gr ELDM, or any of these other bullets? Have you experienced stability issues?
