I hope you decided to buy yourself one of these beauties.
I have one that I bought in the early spring and had just started playing around with it some. Out of the box it would shoot groups in the 1/2 inch range with everything I put through her. This included Hornady "first run" ammo, CCI " several different lots" and Remington loadings in different lots. The trigger was OK from the factory with some creep and with a medium pull for a hunting gun. Squirell season oppened and to the woods we go. Head shots where very easy with the leaves on the trees it's important to pick your shots, because at close range it is a little distructive. My shots sometimes are inside 15 yards, it may be a little over kill at this range.
I decided to do a little trigger work on it, so I cut two coils off the trigger spring. This helped the trigger greatly, but didn't do much for the creep, ( I plan to work on this later on). I then bedded the first 1-1 1/2 inch of the barrell and the rear of the action. I took it out last week and the groups had shrank by almost half! My best group at 50 yards was one ragged little hole about the size of the .22 holes in the next target over. Most of the groups where just over 1/4 inch.
Fit, finnish, and general quality are very good on my gun. I would buy another in a heart beat! I have fallen in love with this 17Hm2 also. I feel this is the best round for tree squirells that has ever been invented, it will realy earn it's keep when the leaves are off the trees! For target shooting, I feel this round is a very good round, when compaired to expensive target ammo in target type rifles.
