9mm Jr Carbine Ejection Issues

Made up some handloads for my 9mm JR Carbine.
Good groupings but 1 in 10 isnt ejecting and jams up.

What would cause this?

OP, whats your load for the rifle?

IME JRCs need hot loads to cycle well, especially the 9mms. Optimal loads for accuracy may not be best for cycling.

Mine likes them hot, anything slow seems to be inaccurate for some reason. But also never saw ejection problems with starting loads though either.
 
If you want something to compare to the load I have been using is 3.5 gr. of Alliant Promo (same ballistics as Red Dot) pushing a 115 gr. Berry's plated RN bullet. I really haven't done any accuracy testing but ejection is 100% reliable with this load.
