My 10T 308 shoots 178 ELD-X with 43.9 gr of varget. Can put 3 in a quarter when I don't flinch. Coal is 2.810. Tried getting close to the lands but it looked like a shot gun blast. Finished load development with the 200 ELD-X not to long ago and now working on the 208 ELD-M. Having good results with the heavier bullets. Considering trying the 185 juggernaut I hear are great bullets.
What's your coal loading the 175?
