RE: Browning X-Bolt JUNK!!!!
Is the Hornady ammo all that you tried, the gun may just not like em. Try some Remington and blue box Federal. I had a Remington 700 in 257 that absolutely loved the 117 gr interlock load, my 98 mauser rebarreld with an ER Shaw barrel shoots patterns with them, put 1/2 a box of 120 gr Federal premiums Nosler Partition and groups inside of 1 1/2". Before you jump to conclusions, did you also verify that the action screws and scope base and ring screws are tight? Everyone I know that has an xbolt loves it after they get used to the minor design differences.
