So it's a new load.

Will it make 1250 fps, I'm not sure! Maybe closer to 1190 fps, your gun 1200-1215...

I hope an epidemic of going backwards to Doubletap levels has resulted. 

1190 to 1215 isn't bad. And it is still full power according to Shadow's chart.

1190? It's always been near the flap of 1230-1250. Where is that from? In looking at other 200 loads this will be lucky to break 1200 FPS.

I just looked what it was with the old 800-X.  1300 FPS. Damn shame!

Yea. Huge loss!

Check Shadow's chart....still a full power load.

Hopefully he won't touch the 165 grain loads.

The 8.2 grain load is Hodgdon's book load @ 1172 fps
We see the 9.2 grain loads of LongShot at 1200-1225 and 9.4 grain loads at 1240-1250.

Is this one round a fluke or are all of them at this exact load from that box. 

Some asked for watered.  Drink up!

Just punched 1195 FPS in my calculator and it's 630lbs. Still 10mm but on the edge IMO.

630 foot pounds is no 9mm, 40, or 45.

There must be a reason Kevin is "downloading" his products. I think he is being more careful, but still offering a quality full power product. It might not be what you (IC) wants, but it is still a helluva lot better than the other products out there, or equal to Buffalo Bore.

Raise the price and perform less to suit a few. I see the Underwood offerings aren't out of stock like in the past. These changes open the door for another like how Underwood stepped into the scene.
