Just finished loading 35 test loads. Ended up ripping my press off the bench while crimping the last 3 rounds.
Luckily, I took Jim's advice and clamped a board ONTO my bench instead of mounting the bench directly into the laminate countertop. Now I'll probably mount the press to a 4x4 with some really long screws.
Sigh. Good thing I got the test loads done though. Have to finish painting a room in our house, then I'll beg my Fiancee to go to the range and test some loads.
