Anybody ever wildcat (neck down) a 45/70?
« on: December 19, 2017, 09:44:09 PM »
I'm no wildcatter - at all.
So, this may be the stupidest question of the year......

But Biggerhammers AR-10 just made me wonder.......   Anybody ever neck a 45/70 down to say 35ish caliber?

I wonder what the ballistics would look like.

I think the .33 WCF was a necked tapered .45-70.  The ballistics are kind of meh.  The .50-110 was necked to .348 and wildcatters have opened to .35 and it is between the .358 Win and the .35 Whelen.

Just too much hassle to go through, I suppose. If you were P.O. Ackley back in the day, why would you bother with necking down an old-school, huge .45 cal rimmed cartridge (which would take multiple steps),  when there were so many better, higher case capacity, rimless cartridges available later on during the dawn of the wildcatting era (1950's-60's). Just a guess.

I've thought about trying it just for fun. You'd end up with something like the JDJ wildcats based off of the 444 Marlin case. I think a 45/70 necked down to 375 in a Marlin 1895 would be a pretty fun set up.

Thanks Yorke.   

I picked up a Marlin in 45/70 and that's what got me to wondering.   I bet a 375/70 would pack a pretty good punch, and with better trajectory than the 45/70.   

Might make it a legit medium range gun?

I have a Marlin 1885 in 40-65.  All of the ammo I have shot out of it is 45-70 necked down.  I bought the reloads years ago because the original factory ammo is worth quite a bit..

Id say youd be good for 250 yards at least. It would probably duplicate the performance of the 358 And 356 Win, and thats not a bad thing!

When I pass, do not let my wife sell the guns for what I told her they cost.

That is exactly what I was thinking of. 

I think that would be a blast and a good brush gun.

Kinda looks like a 30-30 on steroids.

I just read Watters article on the Greevey Express, the inventor built it on a rebarrelled Marlin 1895 and Watters did his on a Siamese Mauser(A Mauser designed for rimmed cartridges).
After the first shot the rest are just noise.
