Unrelated question: have any of you Contender/Handirifle guys experimented with Sptizer (not rubber-tip FTX) bullets in the 45-70? Does it work, or is performance the same? Would weird barrel twist be needed? I ask because 45-70 is a good deal shorter than the original round, and is in a box magazine; so I'd have more options than the lever guys .
There are some pointed bullets for the 45-70, cast lead as well as jacketed. Hornady has some with a soft rubber tip with higher BC that can be used in a tubular magazine. http://www.hornady.com/store/leverevolution
