Range report, the wife ran about 200 rds thru her S&W M&P 22 with this ammo no failures of any kind. However she commented on how smoky and greasy feeling the ammo was. There was a considerable amount of smoke almost black powder like with each shot, but when cleaning it was no dirtier than any other 22lr ammo. Next range trip I'll run this in the S&W M&P AR-15 22 and 10/22. With 22lr the way it is I'll buy another brick or 2 unless CCI or the Remington Yellow Jacket is available
