Nice report, Longshot is a great powder for the .40 overall. Sometimes I've had bouts with it not being very consistent in working up a load, but once I find the "sweet spot" it's very nice and can be very consistent. I've used it a lot in the .40 S&W and I'm seeing good results with it in the .45 Super as well.

Your load of 8.2gr seems good to me, I have settled on 8.2gr Longshot with 180gr bullets. Out of my stock 4" Glock 23, 8.2gr will average just over 1,150 fps with a 180gr JHP. From a 5.3" G35 barrel it's over 1,250 fps and from the 6" G24 KKM barrel it's over 1,325 fps...easily 10mm performance from a .40. Although I've got some 175gr Silvertips lying around, I've haven't tried any yet with Longshot, but I do know that 800x and VV 3N38 will get it to 1,300 fps in a 6" barrel rather easily.

One thing I always thought was funny is how Winchester downloads their 175gr Silvertip 10mm. While they claim 1290 fps, actual velocity is around 1150-1175 fps from a 4.5" barrel. It's funny because at 1140 fps from a 3.5" barrel, your Longshot load is more powerful than what the factory 10mm Winchester load would do from a 3.5" barrel and only a little slower than what it does from a 4.5" 10mm.
