Who uses the 375 Winchester as their cabin gun? Where do you find ammo?

BUFFALO BORE’s 375 WINCHESTER AMMUNITION

For many years (today's date is 11-14-18), I’ve been asked to make a good full power load for the 375 Winchester. Until now, brass was very hard to come by, but Starline is now making high-quality 375 Winchester brass, so we are in.

The bullet we’ve chosen is a 255 grain JFN. We use this same bullet in our 38-55 ammo, but we use it sized to .377 inch diameter in the 38-55, instead of the .375 inch diameter bullet we are using in this 375 Winchester load. This is a tough bullet that will expand but still penetrate deeply enough for use on large critters like elk or interior grizzlies.

In my only remaining 375 Winchester carbine (I long ago sold the others because I was using our 38-55 ammo in my 38-55’s instead, which gives the very same ballistics as this new 375 Winchester load), this load averaged 1,994 fps, from my 20-inch barrel. My carbine is a Winchester 94 “Big Bore" see image below.

You can fire our 38-55 ammo in any/all 375 Winchester firearms, or you can now fire this new 375 Winchester load in your 375 Winchester chambered firearms. For more information on this subject, please read this…… Using Our 38-55 Ammo in 375 Winchester Chambered Rifles -- You should; however, NEVER fire our 375 Winchester ammo in any 38-55 chambered firearm!!!

This new 375 Winchester load operates well below the industry spec. of 52,000 CUP and, as mentioned, is safe to use in any/all 375 Winchester firearms in normal operating condition. This load mimics the original 250gr. 375 Winchester load at around 1950 fps, but we are using what I think is a better bullet.

Enjoy this new load, and God bless.

Using Our 38-55 Ammo in 375 Winchester Chambered Rifles

Our 38-55 ammo is designed to work in all 38-55 chambered firearms made with modern metallurgy for smokeless powder. It operates at 38,000 CUP—the 30-30 Winchester operates at an average max. pressure of 38,500 CUP. For those who are not aware, the 30-30 case is simply a necked down 38-55 casing.

OUR 38-55 WORKS IN ALL WINCHESTER 375 RIFLES

Our 38-55 ammo is also designed to work in ALL 375 Winchester chambered rifles. ALL means ALL. Winchester, Savage, and Marlin all chambered rifles in 375 Winchester. All 375 Winchester rifles utilize chambers long enough to accept the 2.085-inch 38-55 brass, even though 375 Winchester brass is only 2.020 inches long. By using the longer 38-55 brass, we accomplish two things:

1) We get the bullet closer to the rifling’s and this creates a generally more accurate load.

2) The longer 38-55 brass, with thinner case walls than 375 Winchester brass, gives much more case capacity and this allows chamber pressures to drop immensely. i.e. our 38-55 loads give the same performance (a 250gr. bullet @ 2000 fps) as the original 375 Winchester loading, but at only 38,000 CUP instead of the industry max. pressure of 52,000 CUP that the original 375 Winchester was rated at.

TIME-TESTED & WELL-PROVEN

The concept of using 38-55 brass to produce ammo for the 375 Winchester may be new to you, but it is not to us, so please simply read carefully and believe me. We’ve sold hundreds of thousands of rounds of this ammo and about half of it has been shot in 375 Winchester rifles. A couple years before I started making 38-55 ammo as Buffalo Bore Ammunition Company, I was shooting Marlin, Savage and Winchester 375 Winchester chambered rifles and was using good old every-day 38-55 brass in all of them. To be fair and give credit where it is due, it was both Brian Pearce and Mic McPherson that pointed out I could use common, readily available and affordable 38-55 brass to make full power 375 Winchester loads.

I’ve been doing it for almost 20 years now and have not overlooked anything. If I sound jaded on this subject, it is because I am. Trying to convince folks of anything new, can be a futile attempt, so I am publishing this short text on our site and those who choose to believe me are invited to and we would love to sell you our excellent 38-55 ammo for use in your 375 Winchester or your 38-55. You will love how it performs and you’ll be glad you found a source of high-quality high-performance ammo for your 375 Winchester. As a customer, we owe you this type of high-quality ammo and this type of time conserving straight talk. In our 17 years of doing business as Buffalo Bore Ammunition, many thousands of 375 Winchester chambered rifles have gobbled this ammo up and I’ve not had even one complaint, which I cannot say for all of our ammo.

THE TECHNICAL DETAILS

.375 BORE RIFLES

We use a bullet that is sized .377 inch. I am aware that 375 Winchester chambered rifles utilize a .375 inch bore. When fired, the .377 inch bullet will slug/size right down to .375 without raising pressures (we’ve tested the heck out of this) this is in part due to the construction of the bullet, but also due to our powder choice.

.381 BORE RIFLES

We are also aware that many old 38-55 rifles utilize a bore diameter of up to .381 inch, but most are between .377 and .380 inch. At 38,000 cup, there is enough pressure generated by this cartridge to cause that .377 diameter bullet to hit the rifling lands and slug up to the bore diameter (all the way up to .381 inch) and give wonderful accuracy.

HARD CAST SOMEDAY? - MAYBE

We’ve considered making hard cast loads for 38-55 also, (I personally shoot hard cast 270gr. bullets in all of my several 38-55 rifles) but they are too hard to slug up when fired, so the user would have to know his bore diameter and because of this and the numerous questions it would generate, I am still holding off on making any hard cast loads. Further, when firing hard cast loads, they are also too hard to size down to a smaller bore diameter without raising pressures and the thought of a customer trying to shoot a .380 inch hard bullet down the .375 inch bore of a 375 Winchester, has me a bit nervous. So to date, hard cast loads for the 38-55 are not in production and may never be.

If you email me and ask if what I wrote here is true, I will simply refer you back to everything I wrote here…..I will not tell you something more or different than what I have put in writing here on the site. What is written here is based on decades of my experience with my own rifles and with selling hundreds of thousands of rounds of this ammo to the shooting public…… Thank you for carefully reading this information.

Good shooting and God bless.

Best,
Tim

PS

Ps As an aside, because I love the utility of the 38-55 when loaded to full power, I’ll include the following; I own one of each of the Winchester 38-55 commemorative rifles…..Winchester made three different commemoratives. (Chief Crazy Horse, Legendary Frontiersmen, and the Oliver Winchester) These are very functional and highly accurate rifles. I did not care about their collectability, so I installed aperture sights and sling swivel studs and have used them quite a bit. With proper loads, these collectible rifles will shoot 1 MOA @ 100 yards, which is super impressive for lever action 1894 design rifles. If you run across any of these commemorative Winchesters, do not dismiss them as useless collectibles. They are pretty prevalent on the open market because folks do not know just how usable a rifle they are. Part of the great utility of the 38-55 is that with our full power loads, they are capable of taking any North American game including grizzly or large AK Yukon bull moose, but they generate only about 50% of the felt recoil (this is a guess based on how the recoil feels to me) of our full power 45-70 loads……just sayin.

Thanks Dean, interesting article

[Cutthroat lover]

Thank you for the info I’m excited to get to use this gun

[Cutthroat lover]

So I tried all the stores and no one seems to have ammunition. Does anyone here have any for sale

[Dean2]

If you find some 30-30, 38-55 or 375 brass, I can quickly teach you to turn any of those into 375 Win ammo. Bullet Barn has cast bullets in stock .379 245 grain, ask them to swage them down to .377, $54/200 or get the 265 grain 375 bullet that is .376, $84/200.

They also have 38-55 short and long brass, you want the short if possible. $48/50, one box of loaded ammo is $130 if you can find it. Powder and some Large Rifle primers and yuou are away to the races.

X-Reload has 38-55 brass in stock, both short and long as well as 30-30 brass, which is only slightly cheaper.

Rusty Wood has new factory loaded 38-55 ammo at $100 a box. 245 grain cast bullets at 1,300 fps.
