In the January 2016 issue I tested the Schultz & Larsen Victory, bolt-action rifle and a fine piece of engineering it was too. Scope mounting is by dedicated; quick detachable (Slide & Lock) machined steel rings that engage with dedicated, integral bases on the front and rear receiver bridges. The action is also drilled and tapped for more conventional bases too. On reflection I do not think I described the fitting process in sufficient detail, and as I discovered it’s possible to get it wrong, which can also have an effect on accuracy!
The rings are machined from a single piece of steel, which is then hardened and coated to resist corrosion. Locking is by a single, transverse, T-15 Torx screw that clamps the two, opposed claw legs together. Looking at the integral bases shows three lugs per side and two cut-outs, which form a sort of slotted dovetail. In the base of the ring assembly are corresponding cut-outs that drop onto the rear and middle lugs accordingly in what Schultz & Larsen calls summer and winter distances.
These allow you to set the scope forward on the bridges or ½” to the rear. This is done to take up the difference in length of pull (LOP) between shooting in light clothing in more temperate weather or heavier in the winter. If you shoot all year round then you will have probably noticed the difference in LOP your clothing can make! Perhaps not such a British concern, but it also offers another ½” adjustment on eye relief if required.
Schultz & Larsen point out that the T-15 cross bolts must not tightened up with the mounts removed, as you run the risk of pulling/bending the legs in too much, which will stop it sliding into position. If this happens it’s easy enough to use a small pair of adjustable spanners to just open the legs up a fraction, which is all it takes; don’t overdo it!
To fit; slacken off the cross bolts in both mounts, you will note there are two shapes – angled back, which fits at the front and a vertical one for the rear. Locate the cut-out over the middle set of lugs, then while keeping pressure on, slide it forward until it stops and tighten it. Do the same with the rear and you are now in summer position; lock them down and fit the scope! To change position; slacken the screws, pull the mounts/scope back to the central position and lift it off, then re-position the cut-out over the rear lug, push forward and tighten. Please note the mounts are only engaged when pushed fully forward, so that they enter the lugs!
Engagement is positive and return to zero 100% and once understood it’s an elegant and practical system!
