Hey, I can finally solve the mystery of the Alaska Backpacker Ammo for sure & for good. I was able to confirm my assumptions by talking directly to the manafacture.
It is made for VF Grace in Anchorage by "The Ammo Shop" in Kenai.
He makes the ammo & they supply the packaging.
You can buy the same stuff directly from him in his shop & at gun shows around the state. His ammo is tested & meets SAAMI specs. He said he has no problem with folks knowing that he is the manafacture.
If you want to buy ammo directly from him his # is 283-6110.
When I buy a gun in a new caliber I get my ammo from him to start a brass collectio. I've used his 450 Marlin, 41 mag, 44 mag, 45 Colt, 270 Winchester, 32 Special, 10mm, 38sp, (and others I probably can't remember) & have never had a missfire or scary round.
