My Model Six is spoiling me rotten. Took her out today with some reloads. A 170 Rem RNSPCL over 46 gr IMR 4064 in neck sized ( Lee Loader) Federal cases, CCI 200 primers OAL 3.19 velocity ( chrono'd) 2380 fps. Her best group, 3 at 100 was 3/4 inch and the worst ( !) 1 1/8 th inch. These Federal cases are holding up very well, they're on their 10th firing, and neck sizing cases gives no problems at all. A very nice surprise it is! NOT what I was lead to expect. You know the drill, full length size, small base dies etc... She hardly copper fouls at all and is boringly reliable. I like anything that goes bang, but I dont know why I never gave a pump gun any thought at all. Better late than never I guess.
