OK, Sir Spruce, you have a fast rifle for a 19.875" barrel length. Shilen must have done a good job on that one. The Spruce King magazine box and the one I have on my Alder Queen are the same. Get some 404-g/.458 Shock Hammers and set the COL at 3.380" with 79.0 grains of AA-2230 loaded with a drop tube. You can even single load them for special purpose use with a 3.480" COL and 81.0 grains of AA-2230, loaded with drop tube. Do so at your own risk. You will never want to shoot anything else.
Spring is coming so I will be doing that. But will only load the 3.380 length because of my need to keep it simple. Very simple.
