Of course both are very fast burning powders. Fear not, for both will work but are not my favourite powders for 9mm. I much prefer PROMO, which is like RedDot, but you gotta use what you brought, so to speak.
The 135 grain cast is a very nice weight for target. Wish the nice people at LEE would make a 135, or a 130 9mm cast mould.
Anyway, I am talking TARGET purposes only, not high speed or plate knock-down stuff. Strickly PPC target loads. Okay.
The Bullseye load would be 3.5 grains, maybe 3.6 grains, but STOP there. The TiteGroup load would be very similar to the Bullseye load. Never go to 3.9 or 4.0, way too hot for target. 3.5 in either would be very pleasant.
Keeping the FPS below 1000 is best. 980-990, etc. I'm talking target or PPC loads....
