Has anyone noticed the number of split cases? It seems to be 1 out of every 200 and it seems to have increased quite a bit lately.
Call me wierd but it seems the brass cases are thinner as well.

I sure hope they are following the specs. But then they could be leaning more on the minus side +or-.

9mm specifically, RWS brand cases seem to be the most common and looks thinner walled, but a little of everything.
Loaded with 3.9 grains of HP38, 147 grain Berrys bullet. I am thinking that maybe since I shoot around other competitive shooters maybe we have just fired the cases to many times? I also practice around shooters with new ammo as well and since they don't reload I get their brass as well.
Definitely an uptick which I will continue to monitor. I plan on loading up about 5k rounds in the next week and will try to keep better numbers.

Mostly reload 38/357. Noticed Nickle Plated tends to split more often than brass due to the brittleness of the nickle case caused by the heating to apply the Nickle.

Check your cases with a magnet. I don't have much in the way of RWS cases but I do find a lot of S&B 9mm brass in what I pick up after IDPA matches. A lot of them look like brass but are just steel with a thin brass plating. I first suspect this when one of those cases seemed to be harder than others to resize. I checked it with a magnet and found it to be magnetic. Since then, I check all S&B and have found a lot of them to be a brass plated steel. To date, I have found no S&B 45 acp cases to be brass plated steel. I have not found any other brand of brass yet to be brass plated steel either. Other than that, I rarely see case mouth splits and just about all of my pistol (9 mm and 45 acp) brass is range pick up with no idea how many times it has been reloaded.
FWIW, I have some nickle plated 357 cases that I bought in 1974. After loading them 13 times, I quit keeping track of the number of loads and still have not split any mouths. I think it takes a lot of reloads to split a mouth on straight wall cases.
