Thanks everyone for your helpful replies. I have been shooting some blazer, federal champion, and Mini Mag through this gun. I have had the chance to test ammo through a Ransom rest, but have been disappointed with groups in the 1.5 to 3 inch range with most ammo. CCI standard velocity shot ok with a 1 inch group with a flier or two. The minimag 40 grain shot the best, placing all 10 shots in a group smaller then a dime. I will have to retest some of this ammo with a relatively clean forcing cone. Has anyone had an experience of accuracy better then mine with the 617?

Thanks again
