Thanks for the details CJ & I`m sorry if I sounded a little sarcastic !!!

It sounds as if you`ve covered alot with your O3A3 !!
May I suggest trying 4895 with starting load of 28 grs., this should work for both weights 170 & 150
This does good with the Big 314299 bullet, & I have a 311314 (the squib bullet ) & It kinda goes to pot around 1500fps from my 700 Rem.
The squib does better with 18gr. of 4227 slowed to 1400-1450fps.
I size all my 30 caliber except for 1 marlin in a .314 die .
