I have a late 90's mini-14 that does not like my reloads. It has always had accuracy/tumbling issues and I assumed it was just that the barrel was worn out from heavy use back when Wolf 223 was under $90/case. Today I brought 3 loads to the range: American Eagle .223 55grn, Tulammo 55grn, and my reloads (22.5 grn H322 + 55grn hornady FMJ. All shots were taken from 50yards on a semi-stable bench. My reloads key-holed terribly with many missing the paper plate completely, tulammo didn't keyhole but was all over the place, and the American Eagle shot a decent group. I repeated the test twice with identical results. The only difference I noticed when shooting was that my reloads ejected at the 90 degree angle to the gun while the AE pattern was further back. All bullets were 55grn and I have had a lot of success with these reloads in various AR-15's. Does anyone have suggestions for why my reloads suck in this rifle?
