I guess it's a good news/ bad news sorta thing.
Bad news:
There's not many loads being done with FMJ bullets for 6.8 SPC. Remington, Bitterroot Valley, and Double Tap are the only ammo producers doing them that I'm aware of.
Remington is the only one that is ITAR licensed for export according to the list on Canadian black rifle mag.
Good news:
If your planning to put ammo up for a "just in case" thing, there are far better loads than FMJ available. It's worth your while to have a look at the 68forums or the terminal ballistics stickies at M4carbine. Tula and Federal have announced that they are both going to produce 6.8 ammo next year, with Federal dedicating an entire line to production. Should drop the prices to almost what .223/5.56 is going for.
If that happens, I'm going to take a hard look at getting a Tavor re-barreled and bolted to 68. It'd make a helluva bush gun for deer and yotes that I could afford to run for three gun.
