Title: Underwood 200gr TMJ (New Load)

    This should be a non 800-X version since I haven't purchased any in a long time. I will run these later this week with some other 10mm rounds.

That would be like the SwampFox loading 1240 fps if it is LongShot with 9.4 - 9.5 grains.   ::)
BTW no mail today...however the mail service must be screwed up.  If the package doesn't show tomorrow I'll file a lost package claim to see how fast they can find it!  >:(

Yes, the Feds are off today. My buddy tried to buy a gun from an FFL, but found out NICS is down as well.

What's up with the new load, IC?

   I assume it's new as it seems Kevin got away from 800-X.

Excited to see your findings. Have some of this along with 155 xtps on the way.

  I think The Shadow guessed this one pretty good. He must know something  ;D

EAA Limited Pro 4.75" 1211, 1227, 1214. Average = 1217.33 FPS/ 658 LBS
EAA Hunter 6" 1245, 1247, 1263. Average = 1251.66 FPS/ 696 LBS

   This is would be about 1200 FPS in a Glock. With the 220's flying at the same speed now the rating might need to change.

Here was my estimate you were referring to, for those that didn't see it!
QuoteWill it make 1250 fps, I'm not sure! Maybe closer to 1190 fps, your gun 1200-1215... ???
