Good info. Another option is the same bullet type from Beartooth. A bit more consistent quality, but nearly identical profile. DT used to load the BT before insourcing casting.

Thx guys. Interesting the bullet dia is so small for cast, maybe the gc helps there. For the cost of the beartooth, having a mold made seems worthwhile. I would go w/o gc though, only looking to run 1200fos in my g20sf.

Yea I'd like it better if the cannelure was not cut in that one (38-40 style), the lube groove could be higher and a little more lube above the gas check. There are various styles out there without the gas check. Then if the bullet was made without any lube grooves and poly powdered paint coated, that would keep it shorter for the weight, allowing better pressures at achieved velocities.

I can have anything I want from Accurate molds. They have a design I like, no crimp groove but the meplat is a little small. No big deal though, he will make anything you want, same price. Just got 1K Starline so maybe time to get a new mold dedicated to the 10mm.

First run thru the new mold. As cast, ww alloy with a little Lino, coming out at 195gr. I went with a no gc design, 0.0.310" meplate, now for some load dev. No gc should not be an issue running under 1200fps, which is plenty fast for a solid of this type.

Fred that looks great, it looks like it has a bevel to the base. If you want to get a little heavier, that bevel could be removed.

Good luck, let us know how they work and feed!

Yeah I thought about going flat base, but this is easier to cast & load. Most of my cast bullets are fb. Lubed, the bullet will be close to 200gr, 195-200, matters little. I am interested to see which powder gives me best accuracy in a stock Glock bbl.

Thanks for the update Fred. Those look about right! You have my attention. I look forward to your range report(s).

I assume that you're intending to test with the usual suspects: BD, A9, LS?

Yep, looking for an easy 1200fps. I don't think much is gained pushing a solid any faster with the increase in pressures. I'll do a wetpack test against my fav 44mag load.
