    Posted: January/16/2011 at 21:14
Has anyone had this happen to them?  I was shooting my 300 win mag today and the rear ring snapped off at the base and the scope slid forward in the forward ring about 3 inches.  The rifle is a rem 700 lss and the rings and bases were leupold.  The scope is a Nikon Monarch Gold 2.5-10x56.  What is the likelyhood it damaged the scope?  There is some cosmetic damage in that the paint on the scope is scratched off to some degree where it slid thru the forward ring.  In addition to having to buy new rings,  I was thinking about trading it to SWFA on another scope but seeing as some of the paint is scratched off, I don't know what I could get for it.   I guess I am stuck with it now.
 
What kind of rings/bases should I get that are less likely to have this happen?  The OBJ is 56 mm (which is one reason I was thinking of trading it in) so I think I would need extra high rings.

Normally Leupold bases/rings should be fine; were you using the standard bases with the rear windage adjustments? If so that maybe the reason and I'd probably move away from those to Leupold dual dovetails or another manufacturer like Talley's, etc.

I'll let others address your other questions.

Those windage bases suck plain and simple. What mike said on Talley's either the Light Weights or their standard two pc is the way to go.

Was the front ring tight?? I wonder if the front ring wasn't holding anything and the back ring was doing all of the work and that's what broke the back ring.Smile

They were the luepold standard two piece base.
 
As far as the tightness of the front ring, I could not move the scope in it and it was tight enough to rub off a good bit of paint on the scope.

Can you post a pic of it? I've like to see it, because I've never heard of it.

All "windage"  type bases are more prone to failure, though I have been using this type of setup for years without any problems.

Unfortunately, I do not have a camera.  I will try and borrow one from someone tonight and get some posted.
I posted this on another forum that I use and there were several members who had this exact same issue with these scope rings.  I'll never buy another set of leupold rings again.

I guess if I were to mount a 56mm scope, I'd want it mounted with Talley's or something very simular.  The combination of the 56mm scope and recoil of a 300mag is alot to ask of standard rings and bases.

I am looking at the talley fixed rings.  The lightweight rings don't come in extra high.  Do the fixed rings only work with their 2 piece base or do they work with any picatinny rail?

With Talley's (rings/bases) you may not need "extra high" rings since their bases sit higher than most manufacturers. I'm currently using mediums with my scope with 50mm front bell and I still have plenty of clearance (to use scope caps when needed).

Talley's fixed rings only work with their bases (and the soon to be available Williams-Machine Works bases).

How much does this scope weigh?? Was there any gap between the top half and bottom half of the  scope rings?? I'm not arguing with you, I'm curious. Is there any chance that the ring could be slightly over sized??
Marks on the scope from sliding could mean that the rings were some what tight or the rings were slightly over sized making the back ring holding most the recoil?? I don't really know as I've never had this problem. That doesn't mean that this system fail proof, but this mounting system has been is use for 50 years, perhaps. Just because I haven't heard about this happening doesn't mean it has not been a problem!
We do know that the back ring failed and the scope slid through the front ring. This isn't good.Shocked

You could try Burris Signature Zee's or DD's.
I helped a guy put a Burris PEPR on an AR. Obviously, that would not work for you, but the XTR rings look like they're built the same. They sure look like they'd work.

I figured out what happenned.  I have pictures but no close ups to show what actually happenned, unfortunately.  There are indentions on the stem of the ring that are used to hold the ring in place by the windage screws on the base.  The material around the indentions gave away, allowing it to slip free from the base.  I could probably make them work again with the use of a dremmel to dig out the cavities on either side of the ring stem but I decided to order some talley fixed rings instead.  I have officially learned my lesson on the use of cheap rings and bases.

I'm thinking maybe the opposite.  Perhaps the windage screws started to come loose and it did not have as much to bite into and it slipped or maybe it was not set perfectly between the screws.  I had a gunsmith blueprint the action and pillar bed the stock about 6 months ago.   I know he took the scope off to do it.  He may have not put it back on properly.  He is a reputable guy and it not worth pursuing.  If it was something he did then it was my fault for not double checking.  More lessons learned.  I had put probably 50 rds down the barrel since then before it happenned.  It happenned when I went from a lighter 150 gr load to a heavier 180 gr load.  On an interesting note, I can tell that the rings had not been lapped because the paint that was rubbed off was only in spots.  I would think that if the rings were properly lapped, it would be rubbed off all the way around the tube.  Talley rings don't need to be lapped, do they?  I think I have heard that somewhere.

The windage-adjustable rings are very (VERY) prone to failure.  I recommend you throw the bases and rings in the trash and never again buy drift-adjustable mounts.

If, from this, you learn your lesson, it will be well worth it for you.  I've known hunters who had to end expensive hunts because their rings went tango uniform at the worst possible time.  A slippage on the range sucks, but a slippage while stalking a really nice 7x7 elk: that'll ruin your year.

My elk hunting buddy had a new Bushnell scope on his rifle. At elk camp he put his rifle in the scabbard that was on the horse. The horse did several crow hops for some reason and the scope came out of the scabbard. The horse flattened the scope tube and this was the day before the season started. He used his backup rifle for that season. So anything that can happen probably will over time, so be prepared.Big Smile
