I changed to Titegroup powder and my formula is;

1. 147 grain Berrys bullet
2. 3.4 grains of Tietegroup powder
3. 1.14 OAL

I dont have a chrono and want to know how much powder do y'all use (this is why I posted here and not reloading)?

At 3.4 grains of powder the round still seems more snappy than I thought it would be but my guess going from load data suggests around 880 fps...?

I am shooting the CBC in a couple of weeks and while gaming for advantage I dont want to be DQed.

How long of a barrel are you using?

I use 147gr. FMJ, 3.4 gr. Titegroup, 1.15 OAL
In my Glock 34 ~940 fps
In my Beretta 92 Vertec ~890 fps

Glock 17

Yep I'm guessing until I can chrono..

3.2-3.4g depending on a few factors might be really close. Until you get to chrono rounds out of a couple of batches, I wouldn't go any lower. I'd bring mine by one evening, but I don't have the indoor light kit.

I run plated copper Berry 147s at 3.4 grains with an OAL of 1.155 and mine chrono between 895 and 915 depending on temperature and pressure from a Springfield 1911 target model. I have chronoed them myself and was verified at the Texas State match last year. I have since moved up to about 3.5 grains. I hope this helps

At 3.4, I normally Chronograph around 910-915. My standard IDPA load is 3.2 which gives me 870-880 from a 5" M&P.

I use 3.2 grains of titegroup and seat out to 1.165 with a 147 gr. plated bullet from Canada and get 905 fps. With the same powder charge, a Bayou Bullet seated to 1.160, I get 920 fps and it is very soft shooting.
