450 vs 7 1/2's

[Bart]

Flags yes, mostly except times when conditions were near dead. Always 7 1/2's. Holding the rifle as if in the field, not free recoil. Using .002 neck tension. Tried .001, made it worse. Didn't do any jam for fear of bullet pulling if the round needed to be removed. I have seated deeper in the case but a light touch was best. I'll try some jam & see what it does.

Always use flags. There is no such thing as dead conditions. You might try getting some custom bullets that suit your barrel twist. Something in the 103 to 105gr 6MM. I've tried every seating depth you can think of, but I always end up with the bullet in the rifleing. Most of the time very close to a hard jam. I have had zero luck with 7 1/2 primers. CCI 450s are a safe bet. Try taking your loads up to 2820 Fps and then adjust your seating depth .010 at a time. Stick with H4895 or Varget! Try your Night Force scope.

For 600/1000 in cases like the 6BR, XBR, Dasher, etc., given a choice use the CCI450's.
