Thanks Gunfighter14e2 I will check them out. I'm loading for a 16" AR10, I have a TAP155 clone (155 AMAX) but it's not as fast as the M80s so I have to hold high with the 3.5x acog. I'm looking for something light and fast that's a better matchup for the 308 reticle at range, without giving up too much BC. 135s might be the ticket.
