Nothing too exotic but still good!  Shot from Gen4 20 with KKM 4 port compensated barrel (~5 BBL).

New Starline brass and CCI LP primers.

180gr XTP, 11.5gr VV 3N38 @ 1.250": 1,387 AVG - 8.27 ES - 5.65 SD

225gr WFNGC, 9.0gr 800x @ 1.250": 1,244 AVG - 13.05 ES - 9.21 SD

Looks like great numbers, I hope the pressures were reasonable.  Thanks for sharing the range report! 

Good night those are hot 800x loads!  I couldn't get that hot with 173 grain cast bullets.  Started getting imprinted / flattened / cratered primers at 9.4 grains.

Those 800X loads are well over book.  Hodgdon's site lists 7.8 grains as a max for a 200 grain FMJ.  I will grant that you can usually get a bit more with cast bullets, but 26% more is way over what I would try.

Well, you know, the 10mm Auto parent case is the 30 remington.  Being a rifle case and all its SAAMI MAP is .....38,000 CUP.  But hey,  that probably would work out to 45,000 PSI in modern piezo transducer testing.

These loads are well over what the 10mm Auto case and guns were meant to eat.

Yes they are warm loads, but loads I've never had any issues with in years past.  Primers were starting to show some minor flattening but they weren't flat and brass looked fine although it was from a well supported KKM.  Sometimes it's good to let the gun stretch its legs to see what it will do, even if the loads won't see any use 99% of the time.  These aren't loads I would use just for typical plinking but could be of use to somebody who wants the most from their platform. 

I did edit to add a disclaimer about working up loads just in case.   I've got data for .40 S&W pushing 200gr to nearly 1300 fps (6"bbl), but wouldn't post that due to possible ensuing heart attacks 

Looks a little weak to me. Don't be scared
