You might want to gauge the middle left diagram though. Eley EPS cuts quite small holes in current NSRA cards, and it looks too close to the line to score by eye.
It could well gauge out Tim, it was really just a basic function test really. A length of much heavier duty aluminium arrived in the post this morning so will be able to fit a more suitable scope.

Just thinking of elongating the rear mounting hole on the scope bracket so I could reach out to 200 yards if needed and still keep optically centred just tilting the bracket a bit.

I made a scope bracket for my Mk4. I started with some 6061 aluminum angle .25 thick by 2 inches
After squaring the surfaces I ended up .20 thick.
I considered slotting the rear screw but was concerned that it may move. Instead I located the rear screw hole .012 lower than the front screw hole, measure from the top of the mount.
If I recall this gave me about 20 MOA. I have a Leopold Comp 40 mounted and can go from 50-200. When finished I had mine anodized black.
The Martini screws are built to the British Whitworth standard not US, but in this case the 10-32 is an excellent fit and works fine.

I think just fixing it at 20moa might be a wise choice - I'll have a check and see how much adjustment I have in the scope.

Took it out for its second airing today - more suitable scope fitted. Only 25 yards but pleased with the results.

Very nice job on the mount. If you find that you need more elevation you may want to consider Burris "Signature" rings with the plastic gimbal type inserts. The inserts are available in different thicknesses to compensate for various mounting issues. I've used them on centerfire rifles with no problems.

Great believer in the Burris rings - I have them on my two Savage F-12's in 6.5-284 and also in 6BR. Optically centres up the scopes nicely and can adjust from 100 - 1,000 yards with no elevation problems.

The front block is machined out of oak, scavenged from a kitchen cabinet door. The stainless steel strip was machined out of a rough strip I had spare, it's 1/4" thick and inlet till flush.

I machined T nuts from brass to just slide in the standard accessory rail.





I also make these little bipods that fit the accessory rail on all modern target rifles:

"The gunshop was asking 100 (about $120) but I traded in an old pump shotgun and gave him 50."

It makes me cry how inexpensive they are in the UK, the last one I bought cost me about 625 GBP ($800).

I feel you pain, although rather an exception to the rule. It makes us green when we see the prices of almost anything shooting related that is available to you. Barrels, rifles, consumables etc.

Say an 8lb tub of European powder V150, your price $209 (163) our price $344 (269)
