Thanks again, Quick. I called them and I e-mailed them, too. The lady with whom I spoke in C.S. said she'd not heard anything concerning the .338 Federal offering. I informed her I'd love to see it and that I'd be sending them a frame if they did. Also, as far as turnaround time for barrel fitting, she said that between now (June, for people who may read this later) and October was the best time because they didn't have so much on their plate during these months. She also said the turnaround time is about 3-5 weeks during this slower period. Works for me.
I am going to go ahead and send the frame from the rifle I just bought to be fitted for a Huntsman barrel. These primer carriers for their muzzleloaders, do they last very long or is it necessary to have a lot of them on hand?
