Any updates??
I've owned several NEF/H&R, Encore, and Traditions rifles all rechambered to 357 Max and none of them had the same preference for crimps. One would prefer a heavy roll crimp and the next one would not. Testing is needed as there is no firm rule in a single shot.
What I haven't read is how the barrel was rechambered or is it a factory Maximum? Those 357 Mag chambers have a factory "Linda Lovelace" throat that, in some cases, can chamber Maximum brass. I had one that brass stuck upon firing as it was flowing into the throat area. I suspect a light (short) bullet would allow this easier than a heavy longer bullet. I trimmed .010" off the brass and that problem went away.
Don't expect those 140gr FTX bullets to penetrate deeply or hold together if they hit bone. I tested them in wet newspaper at speeds up to 2500fps. While they held together they didn't penetrate far with a 50yd impact distance. Think archery shots right behind a deer's shoulder and they should be fine.
Thanks, Dinny
