This is a quick mobile post from yesterday's outing. With the first shot from the 6.5x55 barrel, cold & clean, I dropped the rabbit seen through the Kahles. Same again with the next two shots, all at 250m. Later in the day I installed the 243 barrel and hit at 230m with the first shots. Very happy with the repeatability and accuracy of the Mauser M03 system.

Hello. I used 20 in/lbs for the screws holding the top rings to the bottom rings and 45 in/lbs for the screws holding the bottom rings to the base. The screws and threads should be clean, dry and oil free. The trick with setting these rings and mounts up well with the scope and rifle is to slowly, gradually and progressively increase the tension on all of the screws in cycles, i.e. the ring screws and the base screws. This ensures the rings are 90 degrees to the scope tube and avoids warping of the base plate. You'll know you've done a good job when the base plate sits on the M03 receiver's square mounts (before swinging the locking tabs) and there is no air gap or rocking of the base plate on the square mounts. The other way of knowing you've done a good job is in several years time when you remove the rings from the scope and there's no marking on the tube. :-) Good luck. Let us know how you go and link some pics for the blog. Rick.
ReplyDeleteI should add, start the mounting process with the mount base only locked into the receiver, but still do the tightening of all the screws slowly, progressively and in cycles. It's when you remove the scope (with attached mount base and rings now) and put it back onto the receiver that you'll see any air gap or feel any rocking between the receiver and the mount base. If so, start again, with the tiniest amount of tension being applied to the base screws first (via the empty magazine well). It helps to have the rifle suspended on sandbags front and rear so you have room to get a long handled tool up through the magazine well to the Torx 20 base screws. No scratching! :-)
ReplyDeleteThat's a great choice of scope. I was very close to choosing Steiner before settling on the Kahles, which I rarely use above 16 x as it turns out. Yes, I meant flexing of the base when I was talking about an air gap between the receiver and the base of the lower ring. If flexing or twisting has occurred, as a result of tightening the ring screws fully before the base screws, it will be apparent when the scope and mount is settled on the receiver, before locking with the tabs. If you do get some good pics I'll make a post of your progress. Regards, Rick.
DeleteAn option instead of epoxy bedding would be to use the Mauser M03 rail mount shown in the post linked below, along with a set of third party rings with canting machined into the ring to scope mating surfaces. It would take some investigating to work out whether the Mauser rail could accommodate the required distance between the rings, as well as what the scope height would be. It would probably be fine. The measurements provided in the post just above the picture of the rail will help.

Or there's this product, though it's not clear from the company's default picture for the product how it mounts onto a Mauser M03 exactly.
