I am having a 308 rifle built. Currently shoot to 800 yards new range will have 1000 yards.
Shot at sea level
175 SMK or 175 Nosler
use 45gr. varget, get about 2750 fps
Currently shoot these loads with 26" barrel TRG-22
New rifle will be 308 Kreiger heavy varmint barrel contour #17 which is 1.25 to .900 with 1:11 twist.
I can make it as long as 28" I believe.
Weight is not a concern.
At what point if any do I reach a point of diminishing returns as fars velocity goes?
