If I add another half a turn, will it be consistent enough? Is this unusual for a gun that is fairly new? Too bad I cant test home. Thanks in advance.
The whole point of "tuning" is to get the lowest dwell possible with no drop offs..
advice to to watch this
basically you're turning the bolt out till it fully cycles and then do 1/2 or 1/4th turns more and u'll be good check for drop offs and inconsistency
but basically u'll end up with something like dwell of 21 and a LPR of 3 complete 360 turns
