Red Dot + 45 Colt

So far I’m not impressed.

I used Rem 2 1/2 primers, 7 grains Red Dot, and 155gr SWC or 230gr (LabRadar S117) round-nose from Missouri bullet co.

230 Grain

LabRadar Series: 117, shooting 100 yards.

Velocity: 840fps (855, 825, 836, 884, 808, 831, 838, 861)

Spread: 76fps = 884 – 808

StdDev: 23.62 (8x)

Notes: This had somewhat sharper recoil than I expected. I had trouble keeping it at steel at 100 yards — admittedly it was the end of the night and I was tired, but anecdotally this has poor accuracy.

Winchester 231

Wincheser 231 is a classic (when??) pistol powder “ideally suited to the 38 special, 45 Auto, and 9mm standard loads” advertised to have “consistency, clean burning, low flash”. It is currently made by Hodgdon and identical to HP-38.

There are consistent rumors that Win 231 may be discontinued in the future, because it is more costly to produce than newer powders.

Bottom line: Good, but seems like a bad idea to get attached.

Pros:

  • Meters well, it has a slick coating and medium-small grains.
  • Low static cling
  • Claims to be flash suppressed
  • Good amount of load data.

Cons:

  • Likely to be discontinued.
  • Unclear how much historical load data has changed now that HP-38 and 231 are identical.

Density (per Lee dipper chart) 10.7 grains/cc
