Shot some today in a midrange 357 mag with a158 grain cast swc pushed by alliant sport pistol. About 1000 fps. They were totally reliable in a 686 with all factory springs in double and single action . My 2020 colt python had some light strikes in double action but not in single action mode. My old model 66 I purchased in about 1984 had a couple of light strikes in double action but I need to correct some cylinder endshake in that gun so l might have excessive headspace or maybe years ago I may put in a reduced power mainspring?
Bottom line:
Like most foreign primers they seem to be a little hard just test in individual gun.
For those that care I purchased a few thousand at 69.99 per thousand plus shipping. I really did not need them as learned about primer shortages in the 1990s and have always stocked up in times of plenty but I like to experiment and hope we have alternatives in the future to the old monopoly brands.
