This is the heavy 22" barrel with the laminated hardwood stock and cheap 3-9x32 scope. So I got 5 different boxes of .17HMR ammo and went to sight this in....shots were all over the place, even at 35yards I was unable to get 3 shots to group tighter than 1", so I cleaned it again real well, made sure everything from the bases up were tight and went out and tried it again. At 70 yards every brand and weight bullet landed all over the target, some as far apart as 4". The trigger is set nice at just about 3 pounds and I am using shooting bags on a bench, so the human factor isn't the issue here. The best they would do (CCI 17gr HP) was 2" at 70 yards. I called Marlin and the person I spoke to said I could send it back, but if it was able to do 2" at 100 yards that would be good enough for them and would send it back without doing anything to it. I wasn't getting 2" at 100, but at 70 yds. still I couldn't believe that Marlin considers 2" at 100 good enough for this heavy barrel bolt action .17 HMR rifle, I consider a rifle that won't do 1" at 100 worthless. Please chime in if you have any thoughts on what Marlin considers accurate or if you have a XT-17HMR that shoots tight groups at 100yds.
