6200 is too low for reliability.



Could be, all I know is the load I use has been thru 2 ND winters with no problems. One thing that someone suggested is to put disposable hand warmers with your shells and rotate shells between them and the ones in your gun. This will keep the shells fairly warm to avoid any problems. Good idea, but to be honest I never used this method, does make sense.

BTW, my loads have been tested by Tom Armburst and do come in around 5900psi.

Best,
