Notes:
- All samples of each load were from the same box, for comparison between guns.
- This is a fairly slow lot of Gold Dot 124+P, in my experience; I've seen slower, but I usually get around 1175 from a G26.
- Interesting comparison between G26 and G43X, with the same barrel length: the 43X was a little faster with 124+P, but slower with 147. This particular 43X also seems slightly more accurate with 124+P, although I haven't wrung it out enough to be sure...
- The Underwood hard cast stuff was just a little smoky, not objectionably so, and quite controllable. I need to do a bit of training and function testing with this load, but it may become my go-to outdoors load. (For the rare occasions I leave the urbs/suburbs.. :rolleyes:)
