Has anybody heard of or used these mounts? cabelas sells their aluminum muzzleloader mounts, but on their website they have an all steel version that looks very nice and comparable to talley's, bases with a recoil and rings with a machined in recoil lug. anybody heard of them?

I looked at these the only problem is that they are not available for any of the actions on the list yet and I didnt get a feeling that they would be soon either they look nice though and the price seemed reasonable.
