Hi all…ready to make my first loads today, but just want to check this out again. I’ll be loading for a .357 lever gun w/24” tube. Since I use 2400 in the M1carbine, I choose to use 2400 with Horn-XTPs in 140&158gr. I’m referencing Hornady, Sierra, Speer, Hogdon,& Lyman manuals. Sierra, Hornady, & Lyman loads w/2400 are using small pistol mag primers. Speer asterisks the ball powders and recommends those to get a mag primer; 2400 got the small pistol primer. Hodgon didn’t show a load using 2400. My understanding is that mag primers are only used with the ball powders. So why does most of the above data use the small pistol mag primer? We’re told when starting with a new caliber to pay attention to the published loads; these seldom agree. Ironically, I’d rather use the small primer. If one changes primers in this case, what is the likely outcome ?
Additionally, in my long barrel, if I do get around to shooting some .38 or .357 pistol loads, is there a minimum load or fps I should stay above to avoid sticking a jacketed bullet in my 24”tube? And finally, since none of these loads will ever find there way into a pistol, how heavy should my crimp be. I’ll be crimping using the seating die in a separate step. One recommendation stated as one approaches mid-level loads, increase crimp; what’s “mid-level”?
Another said crimping was not important in lever guns except when using "near-max" loads.
Incidentally, my starting loads were going to be w/ 140 XTP- 13.8,14,14.2 & w/ the 158 XTP 13.3,13.5,13.7
Thanks to all.
