Have you noticed the 175 grn 277 bullets, Running the numbers this bullet has a remaining velocity 400 fps faster at 1000 yards then the 308 SMK assuming they both start out at 2600 FPS.
200 fps faster then the 190 SMKs at 2600 fps when the 190s leave at 2900 fps.
Not sure the 175/277 bullets would work in my Model 70 Featherweight, but this deffently bears looking into. I think I see my next rifle build.
Anyone know the length of these Matrix 277 bullets?
