That's too bad. I've ordered from them in the past with no problems, but that has been several months. I hope they get whatever the problem is resolved -- they make a nice product. I can certainly recommend Ten-X. I've bought a lot of their ammo, and I just sent 2600 brass to their reload service, which is a lot cheaper.
Edit - Here is what their web site shows. Apparently they've been buried. It doesn't excuse not answering emails or phone calls, but at least they posted a heads up on their site:
We're gonna be closed for a bit ... - June 11th, 2008
As we said in our last note, this is our ABSOLUTE BUSIEST time of year. We're kinda forced to go on a 4-6 week "hiatus" due to our hosting of the Utah Summer Games and then End Of Trail.
Well ... the Games are over, but we're working feverishly to replenish stock in order to take it to End Of Trail. We'll be leaving this Friday (the 13th of June) and we won't be back in the Shop until the 24th. If you're comin' to EOT, please stop by and say "howdy!"
