Blazer ammo is DIRTY. Federal Champion Bulk JHP is CLEAN!. I am anal about cleaning my 10/22 and realized on separate outtings on both brands of ammo I found that I did not have to clean and scrub as much when I used Federal. Blazer left my mags black and waxy and the tip of the muzzle caked with black power and when I took a bore snake to the barrel the soot from the Blazer ammo was coming out like a dust cloud. I like Federal for its accuracy as well. CCI Minimags are not bad either. Have fun with your 10/22.
