i'm thinking of a new rim fire rifle for plinking, silhouette and small game hunting. i have been reading up a lot about the new .17 cals out, .17HMR and the .17mach2 which is considered the best or most practical out of these two new micro cals? has anyone had any practical experience with either of these? especially on the vermin? can you enter standred .22 silhouette shooting comps with one? i'm thinking of a Ruger 77/17 HMR Varmint with a laminated stock, theres one in the local gunshop second hand that i can get a deal on. i'v owned a few Rugers, always had a good run with them over the years, is there anyother rifle make in .17HMR that you would consider better? so many questions, hope you can share some experience cheers, stealth.
