    I didn't do a video because the spring in my mount broke. I also didn't do the Razorback because before I could put the first shot through I noticed the rear sight was loose. Should have Loctited it last time out but... oh well.

    The results should about finish up Kevin's complete line of 10mm offerings. Me personally, I think these are about Nuclear as one should go and be safe (at least feedback I plan to relay to Kevin). SwampFox had some great stuff that really was on edge and I think this lineup is there but with a safety buffer. Results:

Underwood 155gr TMJ (Match 4.75" barrel): 1620, 1593, 1591, 1607, 1603, 1578. Average = 1598.6 FPS/ 879.35 LBS. I predicted 1580, so this beat my guess.

Underwood 155gr TMJ (Hunter 6" barrel: 1695, 1703, 1653, 1653, 1642, 1638. Average = 1666.2 FPS/ 955.29 LBS. Nice gain!

Underwood 200gr XTP (Match 4.75" barrel): 1264, 1269, 1313, 1308, 1323, 1280, 1356, 1306. Average =  1302.38 FPS/ 753.11 LBS. Very nice work on this and now Glocks will see 1275 FPS consistent.

Yikes!  Lofty numbers there!  Why would any 10mm shooters who run factory stuff want to go elsewhere? Great numbers and reasonable prices.. All that's missing is a good hard cast heavy  8)

I do believe that is in the works with a good Barnes Copper as well.

How the heck are they getting 1590s out of a near stock length barrel?  I loaded up some 155 gr on top of longshot and haven't shot them yet, but I'm expecting to top out around 1400 from everything I've read.

Man, those are some real numbers.  Maybe I should forgo loading my own and just get some 200 grain XTP's.
