I have a Marlin Cowboy Limited rifle with a 24" barrel in 45 Colt. I shoot cowboy silhouette in the pistol caliber competition out to 100 meters. I would appreciate any information on a good bullet weight and powder to use in this competition.
I have the same issues with my brother's Winchester Trapper in .45... verrrrry generous chamber! A heavy bullet and a big charge of Unique or W296 keeps the chamber sealed up well.eaglesnest said:I know nothing of rams and chickens, but my Marlin 45 seems to like a bit heavier bullet. Those 200gr I tried seem to dirty up the action as well as one side of my face shooting 9gr of Unique, but the 250gr loads tightened things up very well. That chamber on my new 45 Colt barrel is quite big and needs the added pressure I think.
