[QUOTE="sendero7, post: 300934, member: 18418"] I'm new to the forum and I feel like I'm a little late for this party. If you're still having problems try this. I too shoot a 7mag sendero and mine is a tack driver which took a little extra work duing the break in process. I used J&B polishing compound between each round in the break in. This removed all the microscopic burrs in the barrel. Also remember that the twist rate of your barrel is 1 in 9.25 and will not shoot the light bullets in the 140 weight or lighter. My rifle likes the 150 ballistic tips and 162 A-max and will shoot these in the .2 and .3 at 100yds with no problems. Someone mention the torque screws on the stock at 65 in lbs and Remington says it should be only 45 in lbs. If you're going to shoot manufactured rounds, try Rem 150gr Accu-tip. My rifle will shoot these in the .6 to.7's at 200yds. Hornadys rounds will not shoot well regardless of the weight in my rifle. Hornady actually makes the Accu-tip for Remington. I reload the Nosler 150 straight out the manual using IMR7828 and the Hornady 162A-max with H1000 and both rounds with shoot 2 to 3 inch groups at 650yds. The key is back to the J&B polishing compound which is just lapping the barrel. I bet this will solve your problem. Jim [/QUOTE]
