Just would like to know what the fastest burning powder that's out there being used for 147gn sub's will be using these with a can on my 9mm ar
I like fast powders for lighter recoil target loads and did a comparison "soft recoil load" test with Bullseye, Red Dot/Promo and Titegroup while using 3.5 gr of W231/HP-38 as reference -

I have not tested these loads in my carbines to see if they would cycle the bolt but should all be sub-sonic.
As to comparison of felt recoil, I used (5) to reflect the felt recoil from reference 3.5 gr of W231/HP-38 and used smaller number to note lighter recoil loads and larger number to note heavier recoil loads.
Glock 22 and KKM 40-9 conversion barrel was used with 1.155"-1.160" OAL/COL for Z-Cast 147 gr lead FP bullets (I wanted to use softer 14-16 BHN bullet for the testing of lighter loads for better bullet base deformation) along with .378" taper crimp. Test done at 10 yards and shot groups were measured center-to-center.
Range Test:
I was pleasantly surprised by Promo loads (used Red Dot load data per Alliant) which produced light/mild recoil loads that were relatively accurate. Bullseye produced light loads that still cycled the slide. 3.5 gr Titegroup produced the smallest shot group.
W231/HP-38 3.5 gr - 1.14" with mild recoil (5)
Promo 3.1-3.3 gr - 1.44" with light recoil (4)
Promo 3.3-3.5 gr - 1.10" with mild recoil (6)
Bullseye 2.7 gr - 1.46" with very light recoil (3)
Bullseye 2.9 gr - 1.30" with light recoil (4)
Bullseye 3.2 gr - 1.18" with light recoil (4)
Titegroup 3.1 gr - 1.64" with mild recoil (5)
Titegroup 3.3 gr - 1.26" with mild recoil (6)
Titegroup 3.5 gr - 1.04" with moderate recoil (7)
