I'm glad you got it all set up. My brother just bought the same rifle and I've been shooting it and fiddling with it for the past week. He doesn't reload so he bought some factory Winchester ammo in the silver box (Super-X I think). He bought it with the 150gr. and 180gr. powerpoint bullets. We went to shoot it a few days ago and got it shooting 2.5"-5" groups at 100 yards. That's the best it would shoot. He was ready to return the gun so I told him I'd reload a few rounds and see if there was any difference. I loaded the winchester brass with cci primers, 125gr. Nosler Ballistic Tips, and H380, Varget, and H4350 powders. Went up yesterday and the best groups were down to .7" 3-shot groups. I don't mean to threadjack. I'm just saying, beware of factory ammo.
