.375 RUM scope mounts for Rem 700 ?

[ole-has-been]

Hope I am in correct area.
Looking for opinions for reliable scope mounts for my 375 rum in Rem 700.
I have broken two Leupold sets already, and destroyed one Leupold scope. This was after I had spoke with Leupold and used their recommendations.

Super big fan of Badger Ordnance bases and rings. Understand up front, that you are going to pay for them ($200+ for rings and $150+ for bases) but I would not think twice. These are what we run on the .50cal BMGs on the Barrett M107 and SASS sniper rifles in the Marine Corps. Trust me, they take a beating! No lapping, rock solid and have never failed me. Started using them several years ago and have never looked back.
We spend way to much on rifles and optic to cheap out on what connects the two together!

Thank you for the input. Was hoping for a slightly less purchase price, but hey, I've already lost more than that in past damage. Thank you.

Did Leupold replace the scope?

Did Leupold replace the scope?

Yes sir.

Warner offers a good set of steel rings that I have used in the past. they are much cheaper. I always go with steel rings to limit the possibility of issues like that. Give them a look and see if they fall a little more into your price range.

Thank you......very much

I've got a lightweight .375 RUM I bought from a friend before he passed. I installed Leupold dual dovetail bases and rings and have not had a problem. Much stronger than the windage adjustable rear base. As an aside, I immediately put a brake on it after shooting it one shot. 7# rifles in large calibers are not enjoyable to shoot often.

Hello....
The dovetail rings are what I have broken and cracked in the past. ??? I am just wondering if I should be doing some serious...very serious double checking on ring alignment, etc??? My rifle has a Hoque stock with retracting shoulder pad and also a muzzle brake. However, I've been told these things may make it easier on the shoulder but play against recoil on the scope and rings. i.e. make it worse??? What do ya think???
Let me double check my part # for the rings so we are talking apples to apples sir.

Yep, we are using same bases and rings. just wanted to make sure.
Thank you for the input!!!
God speed

Absolutely The Strongest Base System Available​

Leupold’s famous rotary dovetail rings in BOTH front AND rear bases; there’s no way a ring can shoot off its base. Ideal for large caliber, heavy kicking rifles that can throw a scope off easily, plus light caliber varmint rifles that need an absolutely rigid scope mount to make full use of the gun’s accuracy potential. Dual Dovetail Bases and Rings must be used together; will not interchange with other Leupold rings and bases. Rings and bases sold separately; select the correct base set for your rifle, then choose rings.Those marked “Rev. Frt.” have reversible front base to help get correct ring spacing.

This is what I used

Thank you....this set up appears to be exactly what I am using...

What is breaking, the bases or the rings? I have seen many bases break the windage screw or rings with broken screws. They are small screws and are the weakest link.

I doubt your stock is the issue. Usually shooting hard rifles of lead sleds breaks stuff and there is no cushioning of the recoil.

The dovetail section of the rings are pulling up and rearward out of the mating section of the base. The bases appear to be firm solid against the rifle. My bases do not have windage adjustment. No screws broke etc....However, I am using a lead sled to sight in and this is when the problem occurred.

Maybe as quoted "there's no way a ring can shoot off its base", but I have seen the Leupold rear ring break after a shot from a Weatherby 33-378.

This is exactly what I found when it happened the first time. Rear ring had broken and came out of rotary slot. ??? Second time around, i caught it before rear ring came out of lower base and just as it started cracking. Saved scope this time....

 

[effendude]

Please stop using the lead sled.... It will break the stock, stock screws, pretty much everything on the rifle

O my!!! Don't wanna destroy rifle. What do you suggest, sand bagging....etc?
I'm an old Disabled vet and use a sled for sighting in my rifles. This is the most potent rifle I own, with the next lower being Weatherby 300 mag. I've had two back operations with the last one being just a month ago in Jan 2021. As I hope you assume, I am not shooting currently, but would like to have rifle ready to sight in once recovery is over....

I suggest wearing a heavy sweatshirt, sweater or coat while shooting as well as maybe a sand bag between the rifle butt and your shoulder. The recoil forces must be absorbed by something other than the rifle locked solidly into a sled. Lean forward into the rifle so your body can move back with the recoiling rifle too. big rifles are fun to shoot but punishing if not done correctly.

Like @effendude said, the leadsled is part of your problem due to the lack of deflection and damping in the sled. The reaction forces on heavy caliber carry guns can get much higher in that sled than they would when body supported.

I used to design optical systems and spent some time collecting shock and vibe data on small arms in order to have that data for our stress calculations. I found out firsthand that the forces put on the optics could vary wildly on small arms based on body support versus machine supports. I thought it would be good to use a sled to collect that data since the guns looked like a spaghetti mess with all the accelerometers and strain gages tied to them. So, in an effort to make it easier on myself and the other gun handlers while collecting the data, we accidentally noticed how huge a difference there was if the gun was in the sled.

I used to be the Guinea Pig for my more senior friends when it came to doing the boresighting and development work on their big bore safari guns. Those days required an Advil for sure. But the main point is to suggest a highpower shooting coat with the addition of the sweater underneath. Even if you shoot offhand, that coat will take more of the punishment so you can last longer. There is no choice but to practice with the actual clothes you plan to hunt in at some point, but doing work on the gun or loads is a different story.

I am going to add that I ended up spending as much effort on the mounts as we did on the other moving parts within the sight itself. I didn't see that coming, but it was a lesson I have taught since then. If you use light guns with heavy recoil cartridges, make sure your sight bases and rings are steel, and your fasteners are high strength alloys as well. Be sure to use the recommended thread compounds and torque so you don't strip the receiver threads. There is far too much junk floating around in terms of mounting hardware these days. If your receiver threads are still #6, I would consider having them upgraded to #8.

Thanks for input. Yep, threads already at #8. I've got new mounts, and will use a shooting bag of some sorts for steadying rifle. I'll have to wait just a bit for testing due to recent back surgery.
God speed to ya
