Navaho...
Be careful or you'll have an argument from the 45/70 crowd.
I'll tell you what the 45/70 is needed for...
Pickin' pig snouts through the bung hole end
Flippin pigs over with back gainers with a twist
Whackin' three pigs at one shot broadside
Shootin' pigs through mesquite stumps
Makin' big holes in the mud.
Bustin' rocks
Barkin' squirrels
Giving little boys Big fun with a "Buffalo Gun"
Giving old men big fun with Buffalo Guns.
Watching BIG bullets sail down range, then watching the impacts
Feeding humble pie to range jerks who think their overloaded 44 mags are fierce and accurate...let 'em shoot a TC 45/70 with even a moderate 400 grain load... Tough guys find out they ain't so tough... but the TC is indeed one hole accurate if the shooter does his part. I love it, but rarely shoot it..prefer the .30-30 .
Casting and reloading wonderously accurate bullets
Converting die hard wundergunners from fast high pressure rounds to the slow and heavy rounds of our grandfathers.
I could go on, but i'll leave some for the next guy....
I short,you need a 45/70 and other lever cartridges for the same reason... the FUN FACTOR!!!
