I didn't say or mean that, though reading the statement in context I could see how it could be interpreted that way now.
All my LR rifles use either a suppressor or brake; however, I can spot hit/misses with the .308 and .260 without either. 7RM would be marginal. The rest, no.
Ray and I and the rest of the gang are in Colorado, so come out and shoot with us and we'll see what's going on.
