Marlin .375 Winchester

[stonecoldrc]

I got a Marlin in .375 Winchester in a trade last week. I think I am going to enjoy this one. I have had a Contender pistol barrel in .375 Winchester for many years so I am familiar with the cartridge. I have over 200 cases for it and ordered 100 more from Midway. I already cast 250 grain bullets and have a good supply of jacket flatnose in a couple of different weights. I have been looking for one of these for years, but prices have been pretty steep. I believe it will see some action on hogs and deer in the coming months.

I have seemingly always been enamored with the 375 Winchester.
When I went looking some years ago, brass was hard to find and rifles were way expensive. I wound up going 375 H&H to scratch my itch and load it down to 375 Winchester levels. I am still on the hunt for an actual 375 Winchester rifle, but not as adamant as I once was.

I wish you all the luck hunting with your new rifle!

Winchester 94 Big Bores were chamber in that cartridge also.

Have had one for over 20 years, bought it back when they were reasonable used.
Very fast twist rate (1:12) and Micro-Groove rifling would normally tell you it would not like cast bullets but if driven fast w/ gaschecks the gun is deadly accurate.
The Hornady 220 grain jacketed bullets were made especially for this cartridge but unfortunately they are no longer cataloged. If you can find them at a gun show or on the Web, buy them now. Note, jacketed bullets for the 38-55 are a different shape (short nose length) and usually larger in diameter so be careful. The 220 grain weight is a good compromise between the 200 and 250 factory loads. The 250 grain bullets are a little too long for this case and you can't get enough powder in for max loads; either the powder is too slow and ends up being too compressed or it is too fast and pressures go through the roof. Can drive 220 grain bullets at 2,000+ easy from the 20" barrel, what more do you need?

I traded for a .375 Win Marlin at the end of high school. I spent a summer shooting that thing and loved every minute, but had to sell it for college money. I've regretted it ever since. Enjoy yours!

I cannot get my hands on a .375 no matter how hard I try. Looked over a few marlins and big bores at gun shows with super high price tags. Never seen a contender barrel either. I have a bunch of .375 winchester brass too because I make super mag out of it. It’s only fitting I get a gun in that caliber

I also recently availed myself of one of these, an early first year model. Took it to the range today for its first shoot. I mounted a cheap Simmons 4X on it to start out with. Used some loads that my dad had worked up for his Big Bore with 220 gr Barnes and also some 200 gr Sierra FN with H4198. It shows promise. Neat rifle though and worked fine in all ways.

Les Vollmer makes 200gr, 220gr, and 255gr bullets for the .375 SOCOM, 375 SuperMag and .375 Winchester.

got my 375 "big bore 94" xtr in '81 - a little later, got the matching contender "super 14" in the same caliber with a williams fp mounted on the rear.

I go sierra for their 200gr and the vollmer 220 is great - I use the Hornady data w/no pressure signs.

love my old (pre-war marlin) 35 rem - but the first time I popped a pig with the 375(200gr ww factory load back then) - I was sold!

I picked up a Winchester about 25 years ago at a gun show for $325. I need to dig it out of the safe.
