Having an odd problem when I'm loading 200gr berrys bullets, I load them like normal, seating to 1.230 and crimping separate. But when I chamber a dummy round it sticks in the chamber, I have to pull back on the slide with some force to extract the round. This happens in my M&P, Glock, and all 4 of my 1911's. This is the first time I've loaded berrys bullets so I'm sure I'm missing an important step somewhere. I normally load jacketed and have absolutely no problem shooting or hand extracting my loads. I understand you load plated like lead an drop the charge accordingly, but am I missing another critical step that is causing my problem?
