Unertl Mount-How about the indents on a rail (Read 5293 times)

	Folks- I have a Unertl mounted on an 1885 Winchester repro in .45-70. It has a rail made by Steve Earl. The rail has two half-moon indentations, which is where the rings sit. I have a larger 1" tube "hunting" type of Unertl that is much shorter, and would like to place it on the 1885 and use it, but its rings are only 6.25" center-to-center, not the 7.25" or so of the old 3/4" tube. My question is, since the Unertl rings are clamp-style, should it be ok to have the rear ring tightened to the half-moon indentation on the rail, and the front ring to be tightened on the rail, but not on the indented section? I would rather not have a Unertl smacking me in the right eye during the recoil of a heavy 500 grain load Thanks! Kerry

	If you tighten the mount on a flat, you will likely deform and ruin the cup-shaped plug in the mount. I've run across two mounts that have been ruined like this. The mounts should be tightened into the indentations in your bases. Clarence

	Agree with last comment. Also the spacing is only going to increase of decrease the resolution of the clicks of the rear mount. So going to the 7.25 should give you finer resolution per click.

	Amanda, if the shorter Scope has enough length then just move the front mount where it need to be to fit the length on the rail where the cutouts are. As mentioned earlier clamping with the cups on a flat surface could cause damage to the clamp cups. Those cups are actually hardened and do not bend, they break. If all this is not possible then contact Steve Earl and give him the dimensions you need and have him make you another Rail. OooR ask him if he can add a couple of cup cuts to your rail if you send it to him. By the way with the heavy load you are talking about shooting you do not want a Scope that could possibly slip on the flat rail. HTH Regards FITZ.

	Sounds like I will end up sending it back to Steve for mods. The large-tube Unertl is too short to get the mounts to fit into the 7.25" c-c distance of the cutouts. It will do 6" c-c only. Thanks for the warnings about tearing up the mounts. Too expensive and hard to find to bugger one up.

	Amanda I think you are talking about new model internal adjustment Unertl. If a new style scope, Unertl that looks like a Leopold or something like it, it should not be used with Blocks intended for external adjustment scopes. Tight with one screw in block is not going to hold it on recoil. Reason externals like the exposed adjustment Unertl work with lightweight mounts is they slide on recoil, little pressure on the mount. Modern style scope takes the full force of recoil. Needs a solid ring mount scope connection. Heavy bullet it needs to be even stronger, nothing but the best set up. Big calibers or pistols guys will often use 3 rings BV 20 was the last development of Unertl's external adjustment scope line and works fine on 7.2 inch spaced blocks. It slides on recoil. Boats

	Check out the pictures. They probably explain the situation better than I can. Attachment will open as a Word document. Just scroll down to see the two pictures and the text. Let me know what you think. Thanks!

	Well that's a new one on me. Be interested in scopes model number. I would send the rail to Steve get a third cut added to suit. May work one screw may not. Boats

	That very late scope was designed to mount over a bolt action, with spacing considerably less than the earlier scopes, that mounted over the barrels. My concern is that, even with 6" mount spacing, you don't have enough clearance to allow the scope to move with recoil, and cause the problems described by a previous poster. These scopes can move an inch or so with heavy-recoiling rifles. If I were trying to adapt that scope to that rifle, I'd probably opt for 4.5-5" spacing. Clarence

	That's a "Vulture" they could be had internal or eternal adjustment. (You need to *Login* or *Register* to view media files and links)

	Thanks everyone! I will use the old "Vulture" on a Remington 700 with short base spacings. I bought a long-tube Unertl for my Model 52, so everything is fine. I sort of wondered why all of my Unertls are serial numbered on the tube, but not the Vulture?

	I thought all the Vulture's were internal adjust but learn something new every day. Boats

	"Too expensive and hard to find" You can get replacement Unertl scope bases from Buffalo Arms Co.: (You need to *Login* or *Register* to view media files and links) After opening link there are more on page 2.
