    Gentlemen:

    Mounting a classic, long target scope (internal adjustments) on a rifle barrel can be a real problem when the correct mount blocks are not @ hand.

    I have a Himmerli 300 Meter Match Rifle, caliber .308 Winchester. It is factory D&T'ed on the barrel for scope blocks. I built one of the clamp-on adapter mount/bases to use a 36X B&L scope with rimfire blocks on the barrel. Worked perfect, but the scope was quite high-mounted. see pic below (gun is on a SEB rest).

    I recently acquired a Redfield 3200 24X

    The only set of Redfield Big-Bore Scope Bases I have in my parts stash are two very different heights! I could have had a set of custom blocks made, but I choose a different route.

    Here's what I did:

    I found that a Weaver # 46 not only matched the barrel profile, but the holes lined up perfectly for the rear base!

    I only had to drill one additional hole in a second Weaver # 46 for the front base.

    Next, I attached a set of Burris Signature Zee Rings (W/ the floating, Synthetic Inserts) to the bases, and mounted my Redfield 3200 24X scope to it. Yes, I do have the correct rings for the Redfield 3200, and no, they ain't fer sale!

    I repaired to the range w/ the box of various inserts, ready to do some work to get it bore sighted. I could not believe it! It was about "dead nuts" right from the git go!

    With my ugly mug firmly on the rifles cheek-piece, my eye lined right up w/ the scope eyepiece...and get this, i don't even have to remove the front globe sight! The scope must be lined up w/ the front aperture insert. It couldn't get any better then this...or could it? Yep, it gets better!

    With 0/0 inserts, it shot 2 inches high @ 100 yards, and 1 inch left (there was a stiff cross wind blowing from right to left). A few clicks on each turret, and it pinwheeled the X ring!

    I had a spare set of Burris Signature Zee rings (medium height) in my parts stash, the pair of bases cost me $5.00 + tax.

    Any comments? Has anyone else ever had such a situation before, if so, how did you handle it?

    I run into this a lot, having spare parts and blank base stock is the way to get the gun up and running.
    I am building a mount set for my 40x with a fecker 4 power, using mounting blocks with the taper of the barrel and doing the milling with them attached to get it dead nuts on.
    Nice set-up and good job on the scope and mounting.

    it looks like the rear base has a slightly larger radius than the barrel. could just be the pics though. i think what you've got works & without the correct blocks or access to a machine shop thats about the best you can do.
    the weaver #46 is for the front ring on a mauser 98, a warne maxima or weaver grand slam steel base would probably be a better choice.
    very nice rifle by the way.

    Thanks! I like the idea of attatching the blocks to the barrel, and milling the tops "Dead Nuts" on your Remington 40X. A Heavy Barrel 40X has little taper. The Standard Barrel 40x has considerable taper. @ one tIme, Redfield made blocks of all tapers and sizes. They had sets for specific rifles, or blocks could be purchased individuallly. The floating inserts in the Signature rings can save your bacon in these situations. Zero chance of kinking a scope tube.
