I'll mention this to save someone spending money on something they cannot use.
Hornady makes two different 75 gr bullets.One is a match BTHP.
This one can be loaded to 2.260 COAL and works in an AR feeding from magazines just fine
The other one is the 75 gr A-Max.Despite what some have said,you cannot load the 75 gr A-max in .223/5.56 to a 2.260 or less COAL to feed in AR magazines.At that length,the ogive is set back into the case mouth.
