20 TAC Primers

[Ongaku]

I'm using my usual 205Ms in the 20 TAC but have noticed on some loads that I am getting some pronounced vertical stringing.
What primers have people found to be best??

CCI 450 have given me best results for 40 gr bullets.

Use both 205m's an 7 1/2's, I'd play with the seating depth.

I've had good luck with Federal 205M, Rem 7.5's and CCI BR4's.
