My local FFL was able to find a distributor that still had a new Browning BPS 12 gauge 26 inch in stock when I asked about one. The first few rounds were hard to chamber but it seemed like it was at the brass but I think its because the what would normally be called the lifter was dragging on the metal part of the shell because it looks like it helps guide the shell in so it holds the center of the shell as it feeds. So showing them what I thought was going on had to leave it at half pump unloaded and just the few minutes I guess was enough time for that to spread out just enough now it seems to load shells no issue. Or the was maybe a burr that got knocked off.
