Decided to drag out the Marlin Model 60 this morning. Havn't shot it for years. It has taken a lot of tree rats and bunnies. put about 40 rounds of Fed Auto Match thru to warm it up and see how the iron sights, and my eyes, were at 25 yds. Had to use all the elevation down as far as it would go and still was 1" low. Put up a 6" BIG orange sticker with a 1" black center. 10 rounds of the Auto Match and 1"+ group to the right a little. Then switched to CCI AR Tactical. Both are listed at 1200 fps at the muzzle. The CCI shot low also BUT .... a lot tighter group. Both are 40 gr but the CCI is copper washed. Never had a FTF or jam with either. The Auto match only had 2 touching out of 10. I think all 10 of the CCI were touching. Hard to tell what it would do with a scope, never had one one it.
