I just acquired a very good used Whitworth .375 Express rifle made in Manchester, England. Anyone know anything, pro or con, about these rifles ???

You actually PAID for that (I hesitate to call it a) rifle?

Man you've been ROLLED!!

Box it up and immediately send it to me.

I too have a 375 with the three-leaf express sights. My eyes aren't good enough anymore so I have a Leupold 1.5-5 scope on it. I also put a firesight on the front end in case of scope failure.
It shoots about 1.5 to 2 inches from the bench but I mostly shoot standing sitting and from sticks as practice. I am able to shoot about 4 to 6 inches consistently with two-shot groups fired as quickly as possible.
I think you will be very pleased with your choice.
My rifle seems to shoot Nosler's very well but I shoot a lot of the sierra 235 gr. reduced loads because it is more fun.
Enjoy

I have never seen a Whitworth that I couldn't coax an inch group out of, they have wonderful barrels and tend to accuracy....You get a lot of gun for the money with them....

The Whitworth Express in 375 H&H was the very first 375 I ever owned. Bought it back in the late 70's as I recall. It is a very accurate piece. The only problem I had with it was the stock design. The very first shot from the bench fractured my cheek bone, and lower eye socket. While I was recovering from this, my gunsmith reshaped the stock and it has been a treasured friend ever since.

Frank Beller,
I never owned one but I was always attracted to their appearance. Very English. A good friend had one and it had a great barrel. It seemed to shoot everything well and some loads were spectacular.
You've got yourself a good rifle, IMHO.

My first "big bore" was a Whitworth 375 which I bought in the early 80's. It was a great rifle, very accurate, great features and styling, but it did kick hard due to the stock design and relatively light weight. I traded it for a Brno ZKK-602, which I also liked. Wish I had the Whitworth back. I have used 5 Interarms Mark X rifles and they are all extremely accurate.

Mark X's are very accurate, I've had them in .243, .270, and .458, all were sub MOA.

What loads have people found to be accurate and effective in these rifles? Mine has a lot of freebore so it should take well to maximums based on past experience with another Mark X.

I'll have to join the chorus. I had a .375 Whitworth in the late '70s too. Fantastic rifle. I've owned and shot a lot of rifles since then, including some expensive British stuff, and I don't believe I've ever run across another rifle than was as much gun for the money. Superb accuracy.

Mine was probably the best gun deal I ever did, and it points up a potential fault with the Whitworth, although one which may have been peculiar to mine. I was in college then and a friend bought the rifle new for, as I recall, around $600. We were invited on a deer hunt with some friends of his and as he had been cleaned out by a burglar a week after he ordered the .375, it was the only rifle he had at the time.

We were hunting in a national forest, tent camping, in east Texas. An unexpected, nasty cold front blew in just as we got there and the temp dropped into the teens. None of us had brought adequate clothing for that as it was early in the season and had been mild. The next morning's was the most miserable cold hunt that I can remember and none of us could stand it. We all ended up back at camp early. We were all thawing out around the fire when Ted came in with the .375 slung over his shoulder, his hands nearly frozen because he didn't have gloves. After thawing them for a while, he unslung the Whitworth and, pointing the muzzle down towards the fire (we were all on one side avoiding the smoke), disengaged the safety to remove the round from the chamber. He had not done so before because his hands were so numb that he didn't trust himself. The 300 grain soft impacted in the geometric center of the fire, scattering burning embers as only a .375 300 grain soft at point-blank can. We had to beat out a number of brush fires, and worse, a number of holes were burned in the roof of the tent. Of course, it warmed up that night, and rained - hard. Gawd it was awful.

Ted was horribly embarrassed - and mad - at himself and the rifle. On the way home, he said he was going to sell it right away. "How much do you want for it?" I said. "How much you got, bubba?" How I came to have the astronomical sum of $125 in my wallet at one time while in college, I don't recall. He grabbed the money and said "sold!"

When I got it home, I engaged the safety (a slide on the right side in the same location as it is on a M700) and pulled the trigger. The safety is of the striker blocking type and the striker fell until it engaged the stop. When I released the safety, they striker fell home. Every time. The problem was the adjustable trigger, which Ted had adjusted down to around two pounds. On that rifle, when adjusted that low, something in the trigger group interfered with the safety allowing the sear to slip if the trigger was pulled, with the block catching the striker until until the safety was disengaged and - boom! Ted must have gotten the trigger caught on a branch while the rifle was slung, or pulled it unconciously somehow. I got it fixed -the dealer who sold Ted the rifle fixed it for nothing.

I lost it in a burglary of my own in 1981 and never replaced it. I'm going to Africa next June and hadn't planned on taking a .375 - I have a big double and an accurate .300 and there are too many expenses between now and Victoria Falls to squeeze in the .375 I had been thinking of. This string has got me to thinking of a great .375 that I might just make fit!

"Serious rifles have two barrels, everything else just burns gunpowder."

To add to my earlier post -- I took mine to the range for the first time yesterday. I couldn't stay long enough to set up all my reloading gear but I had 10 or 11 rounds left of cheapo Winchester 270-gr. softpoints that I'd bought to try a friend's Model 70 Safari Express. (The main event was to zero a .30-06 for the pig hunt.)

I burned a few getting centered at 25 yds then put the target at 100 -- got a sub-MOA group, then another after the barrel cooled again.
