Got a Marlin levergun for fun. Wanted something with more oomph than a .30-30 and less recoil than a .45-70, had a .307 in mind. Found a nice Marlin 375, bought it, and was hooked. Immediately started looking for a used 450 or .45-70, found a 2 year old .45-70 for $249.95 in near perfect condition.
In the first year I worked up 17 loads for the .45-70. Here's a sampling:
300g Hardcast @ 1167fps -- fun, accurate, very cheap pllinker load
300g Barnes X @ 2061fps
300g Speer UHCP @ 2247fps -- Practice load for hunting
305g Hardcast GC @ 2073fps
350g Hardcast @ 1566fps
350g North Fork Bonded FN @ 2183fps -- Hunting load
350g Speer JFN @ 2191fps
350g Hornady JFP @ 2200fps
405g Rem JSP @ 1732fps
405g Rem JSP @ 1982fps
460g Hardcast @ 1812fps -- "Rhino Blaster"
500g Speer Tungsten AGS @ 1332fps -- Just because
