From one of my forums over at my place that has connections:
Ok, here is the deal on the Remington, this time straight from the horses mouth, the actual guys doing the work on the gun. Like I said before, they bought out ULTIMATE MUZZLE LOADERS, however they will not use the ULTIMATE BP design, they are designing their own BP, they will use a cut down 308 case as the priming system, and they will also use their own barrels. The gun will be built on 700 short action receiver and will have a SS barrel on in with a Laminated stock, it will be 50 cal., and it will required a that you complete a 4473 in order to purchase the gun. They will begin production in July this year in order to have for sale before ML season. MSRP will be 1300.00, so it will mean I would have to sell them for around 889.00 so I'm guessing. He told me he will bring one by for me to test this spring. I told them that they needed to re-think their ignition system, and make the gun that will not required a 4473, and was capable of using BH 209.
