I have just ordered a CMP .308 M1 Garand and would like to prep some loads. This rifle will be shot in 100-200 yard matches only, no LD shooting.
1) What is the maximum COAL that will reliably fit, feed and eject in an .308 M1 Garand?
2) Also, any load data for light loads (that will properly cycle) with H4895 or H4350 with the 135 SMK/HPBT, 155 SMK/HPBT or 150 Hornady Interlock bullets that I have on-hand.
