375 winchester

[Beekeeper]

Does anyone have one?
A few of the brass I have seperated so far are 375 winchester and wanted to see what kind of a gun.
Googled it and got some info but some of it is confusing.
BP and smokeless both?

.375 Win is similar to the old 38-55. Winchester was looking to make a heavy hitter in the Model 94 Big Bore and created this round.
The brass can be made from 30-30 and the bore is .375 as opposed to the 38-55s .379. The .375 also operates at a much higher chamber pressure.

I have one of the early Winchester 94 Big Bores (top ejection, not side). It can be easily loaded to more power than a 30-30. Kicks pretty good too, especially with the drop of the stock and the very thin recoil pad. I use either Hornady 220gr jacketed SP or cast 375449-GC bullets. You really need to decide which to use, because the rear sight needs to be moved a lot when going from one to the other.

I also load it with BP for my wife (through a Ruger No. 2 -- a No. 3 with No. 1 wood). She likes the sound and smell of BP and the recoil is much, much less. I use a plain base 250gr bullet for that one.

It is very similar to the 38-55 cartridge. The case is just a little shorter and a little bit heaver.

The brass is thicker all the way around to handle that higher chamber pressure. There's only a few jacketed bullets available to be used in the tube magazine of the 94.

I have a factory Ruger #3 in 375. When it is loaded to full potential it will get your attention.

Greetings
I have a Winny 94 with a 375 Barrel on it. I removed the 30-30 tube and recut the threads on the 375 barrel to fit. I load it as a 38.55 but use 375 brass. Not a whole lot of difference with Cast except it takes a couple grains less powder to reach the same velocity. The real advantage I see with my 375 barrel is that it is a real 375 and not .381+ so any cast mold is gonna work.
I would one day like to latch on a Marlin 375 to play with.

I have one in 14" Contender. bought the barrel for the scope on it. I do not think the barrel has ever been fired. I bought brass and dies and then most folks said it was not Boolit friendly. If it is not boolit friendly, then I don't have a use for it, especially in a new bullet/boolit diameter.

Never loaded a round. Barrel and supplies just sitting there all these years.

If there is going to be a discussion about the .375 and the very similar .38/55 the twist should be mentioned. The .38/55 is one turn in 18" and the .375 is one turn in 12". I think the twist is a significant difference for cast bullet shooters.

I have some unfired 375 brass. It looks like it would be a healthy round.

I shoot mostly cast in my .375 winchester and haven't seen where the faster twist has mattered at all. I have one with a 26 inch octagon barrel and one with the standard round barrel. Full power loads in the short one do wake you up right quick. Not so much in the 26 incher which is why I had it built up for me.

You owe it to yourself to break that stuff out and give it a try. It might suprise you.

Good morning
Any one rebarrelled a singleshot with a long 375 barrel for launching 300 grain + boolits at 500+ yards ? I know my 94 Winny with the 375 tube shoots the 255 + grainers with a lot less fuss.

marlin also made a 375 win lever action.
mine seems to do better with 379 sized boolits and 38-55 cases.
but it shoots 375 flgc's fine.

I truly like my 14" Contender 375 Win. It is MUCH better with jacketed bullets than cast. I tried all the Lyman loads with some commercial cast bullets I found (246-gr semi-pointed) and got very poor accuracy. I finally dropped back to a mere 8.0 Unique and at 1200 fps, those plain-base bullets snuggled right in there. I strongly suspect that the accuracy problem was related more to the plain bases than anything else. A GC bullet would likely be as good as jacketed - and I've shot a few five-shot cloverleafs at 100 yards with jacketed bullets.

Recoil with full-power loads is quite stout, but manageable. At the shot from a rest, the gun simply disappears from sight. It rises straight up and torques left due to bullet spin, and ends up pointing skyward next to my left ear. I grip it lightly with one hand and all the recoil energy is taken up by moving the gun, not snapping my arm bones. It is painless to the shooter, but onlookers often back away with their jaws hanging.

I did a review of it years ago. Anyone interested may read it here: http://www.reloadingroom.com/index_files/375%20Win.htm

I have a Ruger #3 with a custom 26"+ barrel set up for Schuetzen. I'll look to see the twist rate.
