VELOCITY. HI LO VAR

6.5. 941. 44
6.7. 991. 41
6.9. 996. 25. Heavy recoil, stopped Here for the day. PF 179 Was good enough for me.
7.1. may chrono next trip, 6.9 seemed stout enough though.
7.3


accuracy was similiar with 3 different charges.

Although I have not found the recoil to be especially heavy at that level, I did find that 7.0grns of Longshot is generally "good enough" as far as velocity was concerned with 180grn bullets and faster in whatever length barrel I had on hand for testing compared to other powders at similar pressure levels.

When you continue testing with the 7.1 and 7.3grn loads of Longshot, I feel sure you will come to a similar conclusion, as your power factor indicates, but even your 7.3grn load will still be well under the pressure limit for the 40S&W.
