McHawk- since you don't mention the LEE FCD, I have a suggestion for you. Way back in the 90's when I was in my Big Bore phase (don't you just love it?) I stopped using my seating die to crimp my Marlin 1895 and the Speer 400gr. I trimmed my brass with a LEE Trimmer, loaded up as usual, but finished off with a Redding Roll Crimp die. If you think you would like to try it, I will give it to you Bud. Shoot me a PM with your address and its on its way. I just saw it in one of my shelves, so its still here. I went to a FCD when shooting a Marlin 444 with Beartooth 270 HCGC just touching the lands, which meant no crimp groove. Marshal recommended it and boy was he right! From then on, its all I use. But nothing wrong with a Roll Crimp, especially if you have a groove, ha. Let me know, I'm up/down from a Procedure on my plumbing. ha I have owned and shot 2 Browning 1886, both carbines, but one had half magazine. My old gunsmith could really tweak the trigger down to about 2 1/2 pounds! I noticed in those two 45-70s they practically had no throat, but I was told the action was long enough to run 45-90, just ream the throat out a bit. I used the Williams FP peep on mine with a 1/16" flat gold bead. Wicked. Good luck to you sir, Jim
