30-30 to 375

You would have basically a lower powered 375 Winchester. Much easier to just buy a Winchester or Marlin lever. Or possibly a Savage 99. If you had of said 30-30 -35 that is something I have been thinking of. But still not much different than 35 Remington. A 40 cal. lever on a straight rimmed case that would work in the Winchester big bore would be very interesting.
 
There's a couple 35 rems here in different formats.
One being a Marlin lever and the other a T/C.

As I mentioned, it's still l'hiver upp'ear.
 
I think that I get the "le hiver" thing - but really - looking at a pre-64 Win 94 in 30-30 - what are you going to gain on that? If 30-30 is not going to get it done, probably need bigger cartridge, different rifle? My GrandPa had a 38-55 in North Sask bush in 1930's - neighbours would borrow it to get their moose for that winter - was a "cannon" in the days of 32-20, various 35's and 38-40 / 44-40 that my Dad used, until he got a bolt action 30-06.

Yeah, winter is still'ear up at 3500'

Not a 30-30 to 375 conversion 'looky, but I'm building a .375-08. Got the reamer and dies, just waiting for a barrel. A 270 or 300gr. in the 308 case won't fit in a short action so I'm probably going to build it on a Mauser.

What kind of velocity would you get with 270-300g
220-235g would probably be a nice combo.
 
I was just looking at my brass 410 cases. 303 British case straightened with a 40 or 41 caliber bullet would be interesting. Possibly done up on a martini or Lee Enfield. I have rounds made up for the Lee Enfield 410 with 41 caliber pistol bullets. Shooting them in a rifle LE barrel would definitely improve them.

Consider my pet cartridge, .375 Kemano. 260 Accubond at 2550fps, uses an intermediate Mauser or long action. It’s a .375 Whelen Improved with the neck shortened so the long or pointy .375 bullets work comfortably.

To form it, just fire a factory .30-06 in the chamber (it’s headspaced to have a slight crush fit on a .30-06), then trim to 57mm case length.

I've fire formed 38-55 cases from 30-30 but they are very low pressure compared to 375 win. I've never considered if a 30-30 case will sustain pressure from 375 charges,.
 
The 375 Winchester case has thicker web and sides. I use reformed 30-30 cases in my 375 Winchester and 38-55. I use cast bullets in the loaded to max 38-55 which are lower loads in the 375. I shoot them in both. I wouldn’t load the 30-30 case up to full power 375 loads. My 375 cases i do load to max.
 
JES a dude in america is reboring model 94s in 30-30 to 375 for multitudes of dudes on cast boolits for example............

they handle the jandle of the 375 win.......... most proberly shoot cast with lower pressure but many shooting jackets.


375win is cool as schit......... lol.
 
Marlin made 336’s in 375 as well as 356 and 307 Winchester. I am not sure if they changed the receiver-barrel threads to V form or not. They did change to V form threads when they brought out the 450 Marlin.
 
I don’t think I’d be going the Win94 route if full .375 loads are planned. There’s probably a good reason why Winchester beefed up the receiver on the big bores. Marlin as far as I can tell from mine didn’t change anything on the 336.
 
I think the “big bore” ‘94 (like the 375win) had a beefed up action to handle the pressures. On a standard ‘94 action, you’d be limited to a lower pressure chambering like 38-55.

Not sure why anyone would do this though. It’s easy enough to just buy a 38-55 or 375win and keep the 30-30 too.

Nice...better shoulder than the 375 -06 Imp./Hawk/Gibb s lineup ?

we had in europe a member of our hunting club that owned a 375 win double express rifle. i liked the look of the cartridge.

Agreed fer sure. I wouldn't do a rebarrel or rebore in 375 Win on a standard '94 mainly due to someone else down the road ending up with the rifle and running factory pressure ammo in 'er. Best to get a proper BB 94 in my book.
