"I'd like to use my Cabelas points but that seems unlikely"
FWIW, Cabela's customer support is stellar. Give your nearest store a call. As mentioned by another poster, they might have used barrels in good shape too.
Too bad you're a little late for the Gander Mountain liquidation...my local store had bins and bins of odds and ends, handgun magazines, shotgun barrels and Boyd's stocks, scope mounts, you name it, all 50% off, and then right before they all disappeared for some reason
they were marked down to 75% off...
