    I haven't used the general bullets but the barnes 140gr and 155gr expanded great in wet news paper (never had one the wouldnt expand fully) with longshot and #7 in 10mm,and 400 corbon.Even 115gr 9mm expands with pedals folding back. The bottleneck 400 corbon is another round that giveS a little more room for solid copper hollowpoints. I've been loading 12.3gr #7 in 400 corbon and a 140gr barnes. I need to chrono it this weekend but I know it expands.In handgun calibers the best thing about this bullet is reliable expansion through heavy clothing. Not penetration. IMO

    Which beats the heck out of having a date with an eye surgeon or a pastic surgeon.

    Define old. Long before I bought a Glock, I loaded up .270 Winchester enough to completely split the case of it. T/C Encore chambers can take one heck of a wallop. The kind of wallop that can sustain a bold reloader in fact. :wavey:

    Tite Group has been known to have pressure spikes sneak up on you; meaning, it shows no normal pressure sign build-up, then a tenth grain more...lookout! Also, use stronger Winchester brass on max or near max loads. It's safer.

    NEVER USE 800X and Mag primers in 10mm, just a reminder... I had to pull down some loads this weekend, save your time and DO NOT LOAD MAG primers with 800x in 10mm, not a good thing.

    Based on this thread and a number of others I've seen on the internet, my question is why those reloading for the 10mm seem to dis-regard almost all the normal, accepted safety rules of reloading? As an example, one guy posted that his primers were a little flat but he thought he could push it a little father. What the (expletive deleted) is it about this cartridge that spawns this stuff?

    Maybe it would help to just admit the 10mm is not a magnum revolver cartridge and quit trying to load it like one. (shaking head in disbelief)

    1. Most (90% or more) factory loads (and most published handload recipes, in fact) only mimic .40SW ballistics. What's the point of all that case capacity if you see no benefit?

    2. The 10mm is RIGHT on the edge of being a significant hunting caliber with the other magnums but unless you load closer to 37,500psi, it's only a service caliber.

    I'm not condoning the OP or thread necessarily; just observing. Most of us don't want to load over pressure. Being over book doesn't necessarily mean over pressure. YMMV.

    The problem seems to be that many of the loading books have been watered down to the point of the cartridge not reaching full potential. That's not true of all of them (Hornady's new manual is pretty hot), but some (Lyman) are EXTREMELY conservative. Look up some 10mm loads for 800-X if you don't believe this. Do you see how the book maxes out at 30,000psi for 800-X? Well the 10mm has a 37,500psi ceiling.

    I'm not saying some of us don't do stupid stuff, and I agree with you that it's almost like a sickness exclusive to 10mm. With .45ACP, I don't go over book at all. With 10mm, however, I have. I think it's just because everyone that loads for 10mm is looking for performance, not just paper killing, easy recoiling stuff. If you just want light recoil target stuff, you have no business with a 10mm. However, if you are seeking performance, you buy a 10mm. And in the same vein, if you are seeking performance, you push the limits.

    I know we do some dangerous stuff, but it's not like 3 out of every 5 of us are missing fingers. We are very careful about working stuff up slowly, checking for expansion, etc. Every once in a while an accident happens, but I doubt it happens more frequently among us than it does among the general gun shooting group.

    Amen 21. The IMR data center lists 30,000 PSI as it's max for 800x. Dang lawyers! And yes. I didn't by a 10mm to punch paper. I couldn't afford a rocket launcher so I settled for the next best thing.

    I think you'll like Hornady's manual. It doesn't have much data for 10mm, as it's really just for Hornady's bullets (155, 180, and 200gr), but what it does have is hotter than any other published stuff I've seen.
