40 cal in a Thureon 10mm carbine

[cote_b]

Anyone have any knowledge or experience running 40SW in a 10mm auto Thureon Carbine? I’d like to go with the 10 so I can run either caliber but not if it’s going to cause issues. Thanks

Both cases headspace off the case mouth. There are lots of people who use 40s&w in 10mm pistols and rifles, but this depends on the extractor to hold the case against the bolt face, rather than sitting in the chamber correctly. If you reload your own ammo, there won't be a huge price difference between the two of them.
