First time in a very long time I had to go shopping for gas checks for 6.5 and 8mm. None to be found at the usual places so I googled and came up with Sage's Outdoors. They not only had gas checks but had them waaaaaay cheaper than anybody. Like 24 and 27 bucks per 1k with only 8.50 postage. Ordered late last night they shipped today.
Youse guys probably already know about this source but I thought I'd give a heads up. These are "Gator" checks.
