Rated 5 out of 5 by Wildman from Super AccurateTried 6 different brands and this was the most accurate out of my 10/22 takedown with Volquartzen lightweight takedown barrel, Ruger BX trigger, Magpul X-22 takedown stock, and Nikon P-22 2-7x scope. This ammo averaged .44" groups at 25 yards (three 5-shot groups).

Rated 4 out of 5 by Phoenix from The finest bulletHowdy, I'm from Central Montana and I own a .22 Henry repeater over the years I've tried dozens of brands and weights and types of .22 LR ammo and i never found anything that out performed this round. Other rounds gummed up my action left tons of residue in my barrel or flew wherever THEY wanted to go. This round always flew exactly the same, left my action running like glass, and i could shoot hundreds of rounds and only find a few specks of residue in my barrel afterwards. I was really impressed by its performance and dependability.

Rated 5 out of 5 by Steve1 from My choice for semi-autosThis is the same ammo as 510 but with a copper-washed bullet. 810 is the same stuff in a 100-round box. The advantage it has over 510 is that it will feed in some types of semi-autos with sharp chamber edges or rough feedramps. I use it in my semi-autos, it's very reliable and accurate in my experience, it's a good load for diagnosing problems with the rifle as well. I have had lots in the past that were loaded with a powder that left large amounts of residue in the gun but all the stuff I've bought in recent years has been reasonably clean burning. It's not as accurate as Gold Medal but out of a semi-auto you wouldn't be likely to notice the difference.
