IMO, not worth contacting. I can shoot Hornady or ATK products and achieve the same goal. Specifically, the 32 ACP setbacks like crazy, and I've read reports that 357 does the same thing. It's a known problem with 32ACP. Just check the Seecamp forum out as well, I'd imagine, Kel-Tec forum. I'd like to blame it on one batch; but I tried several different lots (bought 1 box at at time months apart) and each and every time, same problem - over a 2 year time period.
Not sure, but I think I even noticed it on an old 40 S&W I used to own about 3 years ago.
