I've got a Ruger 77 MKII which was rebarrelled. The scope I did have on it, a 3x9x40 Bash& Lomb will not fit with the new bbl. The bell almost touches the bbl. I can see daylight between the scope ans bbl but you can't slide a piece of paper under it. I was thinking of putting a thin copper shim in the scope rings will this work or is there a way to shim the actual base itself ? My alternative is to buy a high set of Rugar rings I would rather not use the high rings. I'v got to do this evening. Any help would be appreciated.

I would use it the way it is.

I think there are medium rings for the 77 if you have the low now.

I'm not a gunsmith/expert, nor do I play one on TV. Hell, I didn't even stay at a Holiday Inn last night but I have shimmed scopes using an aluminum soda pop can (Ok, ok it was really a Coors light can but I'm trying to maintain the site's family orientation). Just cut the top and bottom out with a pair of kitchen shears, cut it up one side and opened it up. Rough cut it to size and laid it in the ring to mark it for a finish cut. If you need a little more space cut as many as you need as long as the ring screws are long enough. I dont see how you could shim the base on a Ruger.

As long as there is daylight you should be good to go.

.358,
As long as you have light you should be ok, unless you want to use scope caps. I would bed the scope to the rings, this usually adds 1/16" to 1/8" in height. I use JB weld or any steel epoxy. Spray you scope with release agent, apply enough epoxy to cover the rings, settle the scope into the epoxy, assemply the rings using moderate pressure on the screws and let it cure. When your done you will have gained height and have 100% contact on your ring fit.

Todd,
WHAT????????????????, that's about the scarest thing I have ever heard of, if I understand what your saying.

.358,
I think I'd get a set of medium rings and be done with it, but if you have daylight you should be ok..check it again when the barrel is hot to be sure you still have that clearance.

Ray,
Didnt mean to scare you, maybe I am not explaining it correctly. Basicly you are bedding the scope to the rings in the same manner you bed an action into the stock. A perfect fit is obtained, nothing is stressed and the scope fits the rings in perfect alignment, similiar to the way the plastic inserts work in the Burris rings. I did go back and put the calipers on it and I confirmed it created an additional .083 in height. I have used this for years and seen it on military sniper rifles, especially .50 cal to prevent scope slippage in the rings and also as an alternative to lapping. I believe there is also a "how to" page at the varmint hunters association web page under gunsmithing tips. It is also listed in one of the older Brownells books, "gunsmithing kinks". Hope this helps and if it matters three rifles I own have this done and the worst is a 1/2 moa .35 Whelen.

Ok didnt want you all to think I was a lunatic so I went back and found the link.

Ray,
I would be interested in your feedback after checking out the article.

EIGHTY THREE THOUSANDTHS?! How did you do that? Where is the top of the ring?

The gap between ring halves is only .015. Where could .083 come from?

A smear of rubber cement is all that's needed to fill the voids in a scope ring, unless you lap for two minutes, then there's none to fill.

Something's cock-eyed *somewhere*.

P.S.-- I wrote the above before reading the article... I stand by every word. The article is rediculous......or worse.

According to that, building a rifle is like building a house on a crooked, out of level, out of square foundation....and then shimming the roof to make it look right. SHEESH!!

I've bedded scope rings this way and it works great! I use JB weld. It also adds a lot of grip due to the perfect fit. Anyone ever mike a scope tube to see how much variance there is?

Only about three hundred of them. .997 to 1.000 unless it's made wrong.

Thanks for all the quick replys,These are medium rings and I shimmed the bases and the inside of the rings with a strip of aluminum. I wasn't satisfied, so I made a trip to a friends house and he had a set of high rings and they worked great and I don't have to jiggle my head around on the stock to get a clear sight picture. Mr. Atchkins your right quit screwing around and do it righ the first time. Oh the guy just swapped rings with me and I wasn't out any thing but time.
