Not quite the same gun, but the P99 I shoot in Production gets a steady diet of 125 gr Blue Bullets truncated cone bullets over 4.0 grains of VV N320. With the longer barrel of the Q5, you could probably get the same velocity with a tenth or two less powder. The reason nobody in Open shoots 147 gr bullets is that in order to get the velocity they need to make major power factor, they stuff a LOT of powder in the case, and with a 147, there wouldn't be room. Lots of people say that the recoil impulse is softer with 147 grain bullets. Personally, I shoot 125s because I like the way they feel better than 115s and they're significantly cheaper than 147s. Try both weights (as well as 135s) and see what your personal preference is.
I'm new here with a new SF. My SF gets fed the same ammo as all my other 5" 9mm competition guns. 147gr. DG over 3.2gr. of VV N-320 @ 1.148". In the SF, it seems to run between 880-890 FPS and is nice and soft with low smoke, (important if shooting into the sun or indoors) low flash (especially important on indoor low light stages) and clean burning.
Cool thread and I wanted to share my findings for off the shelf ammo in the SF.
These samplings were run thru the chrono and then run on a quick COF to check accuracy and speed.
Best out of my SF was: Atlanta Arms Steel Challenge 115g at 127pf.
Second was: Atlanta Arms Elite 115 JHP at 128pf.
Third was: NC Shooters 125g Match (Fed primers) Blue Bullet at 129pf.
Most of the 147g offerings were in the 132-134pf range and all felt soft. The 115-125g offerings were soft and the most accurate on the COF.
For the money, the NC Shooters 125g was the best bang for the buck.
I reload and shoot the ACME Bullet 145gr RN. Been doing well with them. Took 1st place in the IDPA World Championship this year in my class in CCP division with the PPQ 4". My Q5 also shoots the 145gr well.
I'm sure they're good and your placing in Worlds attests to that, but, Willie E. Coyote's experience with Acme products prevents me from using them myself.
My 5” SF likes 124 gr Federal syntech. It shoots nice and flat with a 12# glock recoil spring, and will make nice little 1-1/2“ groups @25 when I do my part.
I've also used the same load in Production and Limited (Minor), with no issues.
