[QUOTE="NesikaChad, post: 405504, member: 7449"] Wes, Forgive me as I just scanned through your writings. If I understand it right once you got the clean/scrub portion out of the way you were shooting groups with a progressive increase in powder charge. If this is correct then it appears that the gun wants more powder. The groups seem to start large and round and then begin to tighten up as the powder charge is increased. If you took the rifle apart ensure the magazine box isn't binding up at all. It should have some wiggle room and be able to float up/down a bit. Also ensure the guard screws are snugged up. 40inchlbs is the max I recommend using. From what I've learned, a round group that runs big tends to suggest a slow bullet. Dropping the hammer and gaining some speed generally tightens things up. Bergers can be a little fussy sometimes as well. Great bullets and capable of great accuracy. Just a little more work as they are a little more sensitive to seating depth. vertical stringing can mean a number of things: I don't see much of it here though. 1. Bedding (pretty sure that's not the case here) 2. Seating depths aren't consistent 3. Neck tension too high 4. Powder charges aren't consistent 5. Primer seating isn't consistent 6. Weak striker spring (not the case here as its a new action) 7. Poor striker protrusion (not applicable here either) 8. Junk scope? 9. Parallax set right? 10. YOU (shooter) can't hold elevation worth a chit:D Keep at it! C [/QUOTE]
