Dear Cookieman:
I hope I may get into this. I've got a 45/70. So my recommend goes for the bigbore on the same basis as Haywire. I like his reasoning. Badnews Bob has the best answer cause he has both rifles. I cannot agree with Badnews Bob, cause if I had both rifles, I'd be in terrible shape trying to make any kind of sensible decision between either caliper. I hope my answer isn't confusing! :roll:
However, how can you go wrong with either? They both have a long and proven history. I must say that your choice for the smaller one will kick you much less, so you would miss out on all that fun! I've seen, this past season, 30/30 ammo on sale for $10 a box of 20. Ain't never seen 45/70 ammo priced like that. Don't worry about which one you select, cause you'll always wonder if the other was better.
The real selection may get done for you. I warn you! You may someday soon, totally unprepared, come upon an NEF rifle in the course of your travels, and it will all be over! See the rifle, handle the rifle, stick a fork in him, he's done! Cartridge won't matter at all! Don't laugh! This is happening to lots of us, the more knowledgable, the worse it is! It's an infectious malady, with no known cure! It's terrible! If another rifle is acquired to provide some relief, then you've got to make a choice, cause you can really only hunt with one rifle at a time. It can be excruciating!
The post by mag41vance is by no means complete.
But, all seriousness aside, you're making a good selection, and you'll do well with it.
Camping in the Colorado Rockies you say? You should be advising some of us! I hope you post pictures. Woodbutcher
