Started working with NOE's version of the 200 gr. H&G 68 swc. Sized .452, OAL 1.250 with 4.2 bullseye. The commander will jam on the last round using Colt magazines. Not every time but needs attended to. Cleaned firearm and mags. I make a 225 gr rn that feeds flawlessly with same mags. Tried them after jams. Suggestions appreciated and thanks in advance.
Edit: also ruled out limp wrist.
