I found some 75 grain HPBT .223 ammo at just over a "buck-a-bullet" when shipping and taxes are included.

My concern is that I may have an increased possibility of feeding problems. At that price I'd rather not find that out on my own (although I may have to).

Do 75 grain rounds have a history in this regard? I don't have an overall length for this ammo.

I'm running a MilSpec 5.56 BCM RECCE16 with an M4 ramp.
