We have a new vocity leader among 124/125g. HP factory loads
A 10-shot sample of the Winchester USA load #USA357SIGJHP...
...achieved an average velocity of 1418FPS with an SD of 18. Chrono is the CED M2 with screens an average of 10 feet away; temp. was c. 95d.F. Glock 32 with 4.5" barrel.
The group size was certainly adequate--very narrow with some vertical stringing.
I shot a few of the Speer 125GD LE load to verify chrono performance; it averaged slightly less than the last long string I measured.
I plan to expansion-test these WWBs and retest the several other candidates by using fabric in the front of the 1st bottle. I think I'll use 3 layers of denim with 2 layers of cotton flannel in between.
An EDC S&W M&P 357SIG. Ten Glocks sold. NRA life member.
