Went to the bench today to fire a couple strings. I had the power ring backed off some from doing some offhand work last week. I noticed when I ran the power up to 10X, it got blurry and distorted right around 8.5X. Thought it could have been in my head. So I fired the two strings and took the gun home. Had the Mrs. look though it and run the power ring from 2X on up. She agreed it was real. Only now the blur & distortion starts around 6X and it's severe. Don't know what the mechanics of it are. But it's good & hosed. Gotta call the manufacturer tomorrow.

What brand of scope is it?

It's a Weaver V10. Chose it because I've had very good luck with another of the same on a .300 Win. for many years. Also, I was under the impression that this is a scope of fairly non-complicated design, hence non-problematic.

It's not surprizing that the scope went down the tubes. The Weaver V-10 was not designed for use on a 375 WBY MAG rifle. A Leuplod Veri-X III, verible scope in the 1.5-5X20 or 30mm, up to 2-7X40mm is about perfect for any of the 375s.

I'd see if Weaver will fix your scope, and if they will, put it on a good 243Win rifle, and replace it with a big bore scope on the 375 WBY.

A heavy scope like a V10 will cause a lot more problems on a hard kicker. I had a friend who tried to put a 6-18x on a .500A2, why I have no clue. It sheared the mount screws off even with double rings. I told him if it ever stayed on the rifle, the scope would be ruined. I even have a pic of him shooting it with the scope flying off and hitting him in the top of the head. Inertia causes problems for big scopes on big rifles. Try a 1.75-6x Leupold, 1.5-5x or even a 2-7x Nikon, nice compact scopes that will work and look right on a .375.

Actually, this scope weighs 11 oz. I did not figure that to be too prohibitive so as to run into an inertial cato.

Talked to the guy at Weaver this morning. He said their scope warranties have no asterisk pertaining to a recoil limit. He said he's not sure what's happened. But he was surprised (acted like it, anyhow) that something had gone awry. So, I'm sending it back for repair/replacement. I'm willing to give it another go. I've read horror stories in these same halls of scopes costing way more going south with fewer rounds. So we will see.

Fool me once....shame on you. Fool me twice....ya'll can tell me you told me so.

I had to look up the weight, they do make a 2-10x38 that weighs 11 oz., which is sure light enough. The 2-10x50 weighs 15.5 which is more what I would expect. I was really surprised the V10 is that light weight.

Mine's the 2-10x38. Actually, the weight was one major reason I chose this scope. There were even quite a few big-bore gurus who agreed it'd prolly work fine on this gun. Maybe I just got a lemon??

I have Swarovski Pro Hunters on all of my big game rifles. All in Talley mounts and rings and have Never sheered off a scope even after 1000-3000 rounds each. I did have a reticle break on one of the Pro Hunters on a Namibian trip a few years back but I have had that happen on a Leupols LPS also and not on a boomer, right out of the box. What kind of rings are you using?

Using Leupy DD bases & rings glassed on and with the beefier screws.

I've had $40 Bushnells stand up just fine with the .375 H&H and other very cheap scopes as well and never had a problem.

I use a Veaver 3-9 (Japan) on a 300 H&H and that seems to be a fine scope as well.

The heavy kickers aren't the worst thing on a scope. It's the light weight .270 that gets them as the rearward acceleration is greater due to some of the light rifles.

I think you just got a bum scope and I've had that happen even with Leupold.

FWIW,
I have a new "classic" Weaver K2.5 on my Marlin 1895 45-70 22" bbl(I know, it's not a dangerous game rifle, blah, blah, blah. I live in Maine, and don't hunt dangerous game, blah, blah, blah, back at 'ya.)

Anyway, shooting stout reloads (350gr at 2000+fps est., and 400 gr at 1800+ fps), it's holding up just fine. It has 4.0 inches of eye relief to boot.

I was curious if it would stand up to the recoil. I called Weaver ahead of time, and they said, "Should be no problem. If it is, we'll replace it."

Your rifle must be interesting to shoot (ie unpleasant). Big bullets, moving fast. Hope it's tolerable to "roll" with the shot.

Looking forward to you dealings with Weaver, with obvious reasons.

Thanks for the post.

I have yet to find a scope that will stand up to the evil one in my collection, a featherweight .375RUM I built. It's chewed apart and spit out Bushnell's and Weaver's already, so I'm going to see about a Zeiss next and hope it'll stand up to it.

You have to promise not to laugh...promise?
I put a $39.95 Bushnell 3-9X variable on my 8 1/2lb Whitworth 458Mag just to see how long it would take to break it. Over a hundred rounds later it is still intact and holding zero. It is now going to the shop where I will (under gunsmith guidance) run that 458Lott reamer gently up its backside.
I will let you know if it lasts very long.

I'd never laugh.

I've got a $29 red-dot sight on an $800 3 1/2" 12 ga. for turkey. It's been there for 6 years and, other than for some battery changes, has required nothing.

I really think I just got an odd lemon in the Weaver.

OK. Kinda Sorta related question. I'm having a 375 RUM built on right now and I'm making it light, hoping for 8# all up. Money is an issue and was looking at the new Weaver K series, likely K4. $100 . Anyone have experience with these scopes? Optics are supposed to be quite good but this thing is going to be a scope killer I'm afraid. I do have a Leupold 1.5-5 I can swap around onto the rifle if I have to...

Thanks guys

The one unfortunate aspect of the Weavers is that they have a pretty short eye relief for a heavy caliber.......3.25 inch or so(excepting the K2.5)

Other than that , I think they are very good scopes.

FWIW, I put a Zeiss conquest 3.5-10x44 in Talley mounts on my 375 RUM and have never had a problem. Granted it is like 9 1/2 pounds but it holds zero and tracks perfectly.

1 round 50, 100 etc. Eventually all cheap scopes take a dump. Thats why they are cheap. Duh! If you want long term reliability buy zeiss, swarovski, Leupold variX111, Nightforce etc.. For really big kickers I like open sights. They rarely fail in my experience. In actuality you probably don't shoot a scoped gun any better than you do a open sighted one offhand at 50-100 yrds anyway. -Rob

Not so sure I'd subscribe to that theory. Maybe you could elaborate.

I ran the recoil numbers for my rifle and load:

250 gr. bullet @ 3050 fps with 92 gr. of powder in an 8.875 lb. gun = 56 lbs. of recoil @ 20 fps.

130 gr. bullet (of a .270) at 3100 fps with 61 gr. of powder in an 8.875 lb. gun = 19 lb. of recoil @ 12 fps.

Reduce the weight of the .270 to 6.5 lbs. and leave all other things constant, you have 26 lbs. of recoil @ 16 fps.

The recoil of even an air-weight .270 is still only at 1/2 the force and 80% of the speed of the forces that boinked my scope outta whack.

Well......the big brown truck just brought my scope!!

For anyone interested in Weaver's return service, the scope was back to me in 9 business days from the time I sent it. At least 4 of those were transit days.......more likely 6. The invoice said "defective cam tube". I have a brand new scope. It's not the one I sent them.

Back to the bench!!

great news I am planning on getting one of those weavers in a couple of weeks myself. Glad that weaver did you right.
