Hank , I feel your frustration, my Ultra 243 was the same way, especially with most factory ammo. I finally settled on a reload of 87gr Hornady bullets and H4350 a 39.8gr lighter load in the book, and a long 2.75 col. And it will now print any of the 3 bullet styles into a inch and a half group. With the vmaxes sometimes touching each other!!
The trigger pull means a LOT also !! I used the easy method I read about here, by pressing the hammer forward while pulling the trigger,,using a snap cap of course. And I also put a little powdered graphite into the opening on the underside.......that really made it light,, almost toooo light, but it will wear off at some point.
All the other suggestions from the guys are very helpful also. The chicken bone/voodoo one did'nt work for me though. Don't give up just yet.
