After years of M1's and M1a's on the firing line...Just started to use my AR-15 on the line at our local 100yd matches. It's a BM lower with their DCM 20" upper with a 1:8 twist bore. Been using 52 and 55gr smk's with 24 and 25gr of N140 in FC brass. The N140 is difficult to get locally most of the time. So I bought a lb. of Varget. Anyone here use Varget? If so how light of a pill can be pushed down the bore with reasonable accuracy IYO? I was told not to use anything lighter than 69gr bullets for decent accuracy with this powder. Thank you.
