My dads Sig P250 .40 blew out the right hand side of the recover and demolished the extractor on his 3rd round ever madeOverkill0084 said:It's been my observation that the .40 is treated as a somewhat evil cartridge that will blow up your pistol if you look at it cross eyed. My experience loading it has been positive. I tend to stay away from max pressures since my needs make them unnecessary for my use. Like any other new to you cartridge, approach it with respect and work up from minimum. Since I bought a 1911 chambered for .40, I've been using it more lately.
All the usual reloading rules apply. The biggest thing is: Get stupid and it's more likely to bite than other lower pressure cartridges.
FWIW, I've had good luck using AA#5.
MBC 180 gr cast are very accurate for me as well.
The round is no more of a problem than any other. Just keep your loads consistently safe. Use only loading data from known/safe sources, watch your process and components and maintain the same C.O.L.Thinking of buying the new S&W SD40 VE. Any thing special to look for when reloading those cases?
