The .375 JDJ destroyed Leupold scope rings.

[bigbore442001]

I was at a friend's range this morning with my dad and the TC. I was shooting at 25 yards to get it on paper when it seemed that the scope was really out of adjustment. I knew there was something wrong when I felt something hit my face.

As it turns out the recoil actually destroyed the Leupold QD scope rings and the 4 X Burris was hanging on by one ring. The steel blocks that set in the Weaver grooves shattered( that must have been what hit my face) and the scope jumped forward. In addition, the base itself was marred and gouged.

Needless to say I was really dejected when that happened. The moose season is 3 weeks away. So Dad and I rushed to some gun shops and we were able to pick up a base and some rings.

We had to modify the Weaver base to accept the extra two holes( the barrel has been drilled and tapped for six holes) and then mounted the scope.

So it is back to square one to sight in again. Hopefully we'll be ready for the moose season. I wisely set up a 30-06 Encore as a backup just in case this flubs up.

On a brighter note, after we were shooting, a young moose actually stepped out about 75 yards on the range and was looking at us. Believe it or not, Massachusetts may have 700 or so moose. Hopefully this means we'll get one.

While I like Leupold rings and mounts alot I think the QD rings are the weakest rings made.  I am not to surprised on a hard recoiling pistol like yours they would give up the ghost.

Good luck on the Moose!

I had the Leupold QD rings also. I had them mounted on my Encore in 45-70. I busted the rings after 4 shots, I sent them back to  Leupold and they replaced them with a new pair. I again mounted them on my Encore in 45-70 and the same thing happened. I again returned the rings to leupold with a letter explaining what happened and I told them I did not want another pair of the QD rings and asked for the non QD rings and that is what I received from them. I have not had a problem with the non QD rings.

If you're going to shoot a .375 JDJ put a T'SOB base and four rings on it. Then you'll have no more scope/base/ring problems. If you don't look for more problems.

Any time you use QD's on a high recoil setup there is a chance you will have these problems.

Ive purchased several items from Gary Reeder. He's hunted w/ contender & encores for years all over the world. His 378gnr I believe is more powerful than the jdj cartridge. Gary believes that all thats needed is Leuopold STEEL rings and base...not the quick release type.  He put some small drops of epoxy when he mounts the base. Its my understanding that the TSOB setup isnt steel. That may be why you'd have to use 3 or 4 rings to make it hold up. Ive purchased a 378gnr barrel for my contender and have it mounted exactly as noted above. Ive had no problems so far. So this is something else you might try. Simply steel rings and base, plus a good reliable scope (burris, bushnell or leupold).

There  is a fair amount of strength in a Leupold double dovetail mount if used correctly.  Not to much in the quick release style.  I can't see paying twice the money for half the strength.  I guess I could see it if you could move the scope around to different guns without having to re zero each time, but of course you can't.

Not to get off topic but, I have a S&W500 Mag and I have a weaver aluminum mount holding my red-dot sight on and over 2000 rounds fired. I have not had a problem with an aluminum mount. Also on my 45-70 when I busted the Leupold QD rings, I had the T/C aluminum mount on my Encore. The mount held up, it was the rings that busted.  

[Graybeard]

Actually there is a good reason why the T'SOB is made of aluminum and not steel. Properly treated aluminum of the right type can be nearly as strong as steel but more importantly is far lighter. When you're working with a heavy kicker the lighter the base/rings/scope combination the less stress it puts on the mounting system.

Likely the ONLY reason the Reeder set up is holding is the epoxy. It really is a good idea which such heavy kickers but it is pretty much permanent so if you figure you might ever want to remove it then not using it is a wise idea.

I mounted the scope on my .375JDJ with a T/C Maxima (Warne) base that I had an extra set of holes drilled into the base and the barrel drilled tapped to accomodate.  Use 2 of the Maxima/Warne rings to hold the leupold 4x onto the base.  It seems to be a solid setup so far....

Also have been using the QD rings, haven't got around to changing over to the solid ones yet.  They are holding very well.

[Keith L]

Take a look at the cross section of the Leupold QD ring's holding posts.  They are tiny, and fragile imho.  The rings you show in your post are far more robust.

[Redhawk1]

Warne are great rings and bases. I use them on all my Encore's. I prefer the Warne rings to the Leupold rings.

I also have the .375 JDJ and use a Weaver base and Weaver 4x4 rings.  I have never had a problem with this set up and have had this gun for two years and shot over a thousand rounds through it.   :grin:

[wheelgun]

I also have the 4x4 weaver rings ( 3 of them ) on my 375 JDJ and a couple of other barrels never had a problem.
