I'm interested in a 617 .22 and I'm tossed up on the 4 or 6 inch barrel. So you think there would be much difference in accuracy when shooting at 25 and 35 yards? I plan on taking it with me every time I go to the range. My current .22 (which will finally get to stay home) sees 200 to 300 rounds each session and I expect to do the same with the 617. Based on that info, what would be the better choice? Thanx
