They cast at .457 and I then use a rubber hammer and dowel to drive them base-first through a Lee .451 sizing die. They go down slick as a whistle and stay put. EASY to load, no short starter required.

The 98 is listed on the site under the online catalog category for Rifles. It is called the Elite Hunter.

I believe it is something of a modification to the 91 but cannot say for sure since I've not owned that model. I did briefly own a Thunderbolt and was one of the first owners to help with some design changes. I hope they are all resolved as that could be a very fine rifle. The 209 is not required though. Another fellow that could help you out with great detail is Tom Lodge [email protected]. Tom is something of an expert on the White rifles as well as an extremely helpful and personable guy. He is also a White dealer and came make you a pretty fair deal.

Best of luck and let me know if you get one. I'll teach you how to make these bullets if you get a .45 .
