Re: Amax jump
When you guys talk OAL dimensions are you referring to an average length? I haven't found any bullet, whether polymer tipped or HP, that measures the same length. Always varies a few thousandths.
When measuring from the ogive, given generous magazine dimensions, a mean average OAL to fit the box makes sense while experimenting with jump distances to where the ogive contacts the rifling, right? Too little jump must leave one or two too long to fit in the magazine at times, correct?
I personally take an average measure around a mean of 2.820" which fits all my bolt guns though is a little snug in my AR-10! Those latter get bumped down to 2.800"
