Re: Help!! Horizontal groups....
Kind of sounded like the barrel may be touching the stock at some point. Then I noticed your last post. My friend has a ruger just like yours that simply will not group with any weight boat tail bullet no matter the powder charge, primer, brass, seating depth. He had the barrel touching in one small place near the fore end. That was fixed by his gunsmith and it grouped better just nothing even MOA still at any range. Feed it any flat base bullet and it shoots right at MOA with everything but the 117 to 120 weight bullets with no regard to seating depth. He limits his shots to inside 300 and has taken several nice deer with it. They didnt seem to mind that it was 3" from the exact place he aims. He's had his to the smith several times with no improvement trying to chase down everything from recrowning the muzzle, to lapping the barrel, to checking fired brass for irregularity and casting the chamber. If you run into something post it up!! YMMV
