[QUOTE="Ingwe, post: 754557, member: 35101"] Good to hear Joe. What started the paranoia is that I was using (7mm RemMag) 160gr Trophy Bonded Tipped (Factory loaded rounds by Federal Premium) that were wobbling at 100 yards...still grouping 1" but cutting oval holes which I didn't notice at first. Those bullets are "1.458 which I guess were too long for my 1:10 twist. Dammit. I switched over to 160gr Accubonds and as I said earlier, they are shooting .25MOA at 100 yards. So now I am wondering what the Accubonds are doing at 300-400 yards.....I live in the NYC area and I do not have a range past 100 yards to find that out, so this is where my post is coming from. The Berger twist chart is calling my Accubonds "Marginal" so this is what set me off. Keep it coming Fellas!! PS To my friends here...Besides the FREAKS who live and work in Manhattan, I don't know even ONE New Yorker who is for GUN CONTROL!! Please don't lump us all into one catagory! [/QUOTE]
