Not personaly, but we just picked one up for the B-inlaw in .223. He mounted a Tasco 8-32 Target on it and we ran some White Box Winchesters through it to get things started. This is the High Profile one with the black tip on the stock. The one thing I really like about this version is the grip abgle. It is pretty much vertical. Any how, we got dime sized groups with no trouble with the little 45gr Winnies. Being a 9inch twist barrel, I expect better from the 69 gr Sierra for Grounghog Target shoots. He plans to use it in the factory class.
