OK, so I recently purchased a cooper 30-06 and it had Leupold bases, so I bought Leupold rings 30mm size mounted the scope, bore sighted it, had everything tightened nicely, and three days ago I came home from the range confused because the rounds were flying all over the target.
I pulled out the bolt and started to get my cleaning stuff ready when I noticed the rear scope ring had broken loose from the mount and the "ears" on the ring base were kinda shredded, and moved forward about 15mm from the mount point so the scope was wiggling all over So, I ordered talley bases and talley rings 30mm, the tactical rings and just realized from the on-line pictures of the ring bases bases that they are different heights. So, any suggestions on how I should mount the bases and the rings; honestly I only want to do this once - and I'm really irritated that I had spent several hundred dollars on a rifle and scope and the rings blew out - I think this might have also hurt the scope too; not sure yet. Long story short which base gets mounted in front position on the rifle, the high one or the low one??? Thanks for your help. |

Welcome to Optics Talk.
So, you have a canted rail, I assume? 20 MOA, perhaps? If so, thicker or higher end of the base is to the rear of the rifles action Here's my 30mm Badger low ring, on a 20 MOA EGW picatinny set up. |

Here's the same ring/scope combo on a 20 MOA Badger rail.

Those look like the Tally rings I bought but the bases are these: |

Oh OK.
I haven't used those particular bases. I've used the vertical split Talley's and the light weight rings, which I love, as do others on here. The LW's are $40 and strong as heck. I'd guess the the thicker base goes to the rear, but I'd suggest calling Talley in the morning and ask them directly. They are very nice people and can help you get squared away. Sorry you've had such a bad time.

Thanks for the help - I'll give the Talley folks a call, they should enjoy this on a Monday morning, start the week off with a a little help and some grins. The mounts and bases should be here by Wednesday, then I'll remount the scope and figure out if it's buggered up too or still works. But at least the problem is something I can fix myself. Thanks again

I thought you already had the bases in hand. They may come with instructions.
I'd still give Talley a call and ask them any questions you may have and they will be glad to help you, I'm sure. Let us know when you get that Cooper up and running and post some pics for us. |

My order arrived today,
BUT ---- the Talley Bases have FOUR (4) different size screws in the Box/ bag. looks like they are stepped in sizes from 5mm to 11mm and I tried to install them three different orderings but they are too long and the bolt does not retract. Called Talley - they are sending me out new screws tomorrow; - good for me. But I'd like to know how that would happen, it doesn't seem like it would be accidental; if either a machine or person were packaging the product. Nope, not happy, not at all. |

More than likely that base assembly is also used on other receivers requiring different length mounting hardware. You can be sure that Talley will make it right. GREAT people.
Did you find out which base goes where?

Hey for once something was easy - the bases are drilled differently and I did call Talley, so I know which one goes in front and back; even here nothing was just one question because the front base is not symmetric and there is a forward and back facing portion here - fortunately Talley folks explained that one too.
You were 110% correct, Their person on the other end of the telephone was very friendly, patient and helpful. When I get things mounted, I will post pictures of the bases and rings and the install so this might be helpful to someone in the future. I'm guessing the screws should be here by Friday or Monday; thereby giving me time to look for a scope for my old Remington 740; apparently Pa had a scope on it a long,long time ago and didn't like it; I shoot well enough with irons in the woods so scopes were never a passion until now. |

As a good rule of thumb, I would avoid the rear windage / front turn-in style mounts like the plague whenever possible. As you've seen, the rear windage base / ring connection is very weak.
I'm glad you got the screw orientation worked out. The reason for the different screw lengths is because the screw holes go through the receiver wall, and on the front receiver ring, if you use screws that are too long, they will interfere with the barrel threads and the top locking lug on the bolt. |
