My 930 SPX has 400 rounds through it so far with one failure. The only failure it had was a bad shell as the primer had been struck but it did not go off so in my book that is 400 perfect rounds. It had a break in of 100 3/34 DRAM game loads and the last 300 rounds I've shot have been cheap federal bulk pack from wally world.
