What I like about the Necked down 445 case to 35 is the use of B&D dies just to locate the shoulder at the proper position, then use a 44 mag carbide sizer to size the lower body IF NEEDED.

Same principle as the Bellm rounds.

Only thing I'm not sure of is if the B&D reamer could just be run deeper to do this.

A 30 cal version has been done already by the steel shooters. That one is a custom die proposition. I think they were getting 2200 FPS with 130's but I'm not 100 percent sure on that.

You'd need to call it the "358 tweener." Just in between the Bain and Davis and JDJ.
Worth the effort?

The 30-445 has been done by VVCG. Charlie Siemplekamp bought the reamer and had a couple Encore barrels made for he and a friend. VVCG didn't do a real smooth job but the round had a lot of poop. I know of one other gentleman who is working on a 30-414SM and he is going to try to do it an a DW.

Charlie no longer is on any of the forums, I think he lives near St Louis.

The 445 supermag necked to 35 has been done by Gary Reeder. If it runs true to the rest of his custom chamberings, I would say it has a very short neck and would be the hottest round possible on the 445 case necked to that caliber.

Headstamp,
Ref. "Only thing I'm not sure of is if the B&D reamer could just be run deeper to do this."

No it can't because of the rim cut on the reamer. Reamers for rimless rounds can be run deeper, but not the ones for rimmed unless they are cannibalized by grinding off the rim cut, which I have been known to do.

Minus the rim cut on the reamer, it then means the rim counterbore must be cut separately, but since I lathe bore most of them anyway, this part is no big deal.

Actually, I almost prefer to lathe bore the rim cuts, and when there is ample end clearance up front, I often stop a reamer a few thous. short, then finish the rim cut with a boring bar.
