10mm never caught on cuz the US doesn't do the metric system well.
Ya......... This is probably why nobody uses 9mm?

The Germans invaded.
My non-brass cases were a big lot of R-P nickel style. I've had very low fracture rate from them, but absolutely zero with the brass-brass mix I've accumulated. All started with new status, either New Loads or New Brass to feed my reloading habit.... oddly you rarely find '10mm' range brass laying about in my sector.....
Not sure why this is the case, perhaps nickel isn't as maleable as brass and causes the underlying brass to be more prone to splitting?
You're disappointed?Are you even trying?? Maybe you need a few more grains of powder.
In my long career in Cowboy Action matches, most often I used 45LC both pistol & carbine. Tried the same experiment over a decade of low-pressure cowboy loads. While my "reloaded # of times" was not exact data, most of my brass lasted dozens & dozens of reload cycles. Failure to cracked brass was perhaps average 3% per match (>175 rounds each/twice month or more) the split nickel cases ran about 3:1 brass brass. Almost all the brass case splits were case mouth, rare was the 2/3 case length. Almost all the nickel brass splits were mid-body & not as far as case mouth. Same powder loads, same lead boolits.
You're disappointed?
agree on the difference in full power high pressure vs low pressure case dynamics; however most of my 10mm loads are at the lower end of the recipe scale as well;I'd expect your 45 LC failures to come from repeatedly belling the mouth of the case and crimping.

in this case your supposition is flawed, as there is very little belling and very little crimping as both are minimal in such loads. And the nickel cases had the same process, same die belling/crimping, etc.
did you miss the part about how many reloads and how few splits?but the cases are still splitting,
I do not reload, and mostly buy Underwood Ammo and they make a lot of choices. They use a different Nickel Case, here is their descriptionMine as well. I'm always running around grabbing 10mm brass off the range floor. I get a lot of weird looks at my range since 95% of shooters there barely know how to load a magazine and pull a trigger.
Anyways the nickel plated stuff is expected to have a reduced life span. Not sure why this is the case, perhaps nickel isn't as maleable as brass and causes the underlying brass to be more prone to splitting?
Are you sure of 13.4 @ 180/200? What kind of velocities are you getting? (My Speer and Alliant's online tops out at 11 grains of BD for 180 = 1295 fps)I have been reloading 10 mm for a while now, settled on 13.4 Gr Blue Dot under any thing 180 to 200 gr bullets with no pressure issues, and so far no split brass.
