Beartooth probably has an LBT design, if they say it it is, as they did start out with our molds, lube etc. However they haven't bought anything from LBT for around 12 years.--------------------- May I strongly suggest that you check out what MontanaBulletWorks.com has to offer? I can enthusistically endorse their quality and the integrity of Dave and Marcia at MTW, but due to the feedback from their customers, (complaints) I can't endorse Beartooth in any respect.
I recommend the WFN for all 10 MM pistols. 200 gr can be sent off with wonderful power from the 10MM, but I believe I would lead toward a 180 gr for most uses. For the 40 S&W, go for 160 gr for best speed and killing punch. The 10 MM will probably do best with gas checked bullets, whereas the lower pressure and velocity limits of the S&W does not require checks.
