Well, after many, many years I did end-up digging out my old leather tools and that chunk of hide I had left stashed away.. spent a couple evenings in the shop these last few days and figured I'd post what I came-up with.
The scabbard itself is 42" from the bottom-tip to the edge the flap is attached.. measures 46.5" to the curve of the flap when it's buckled closed. Used two different rifles to settle on the sizing and length, one thumbhole and one standard monte carlo sako stock.. (soon to also be thumbhole) Both rifles have 26" pipes, one of which has a brake. The scope I have in the attached pics is (obviously) a Zeiss Diavari 6-24x56, very big scope and fairly bulky turrets* There is "room" (some) inside the scabbard, it isn't tight or any-stuggle to force the rifle in or out, at-all! And the way I cut that slot for the bolt, there is actually ZERO pressure on the elevation turret. Upside-down, that slot in the scabbard in-deed holds the rifle completely "up" and off the turrets/barrel altogether... The "other/2nd" rifle I used for fit has got a scopecoat over it (is a Huskemaw 3-12x42) and with the scopecoat it fits almost identically inside the scabbard as what my big Zeiss does, but with the extra protection of the scopecoat, fwiw..
My tooling is a little rusty, lol.. but I figure for eye-balling and going off the top of my head (entirely) for making this thing, it still oughtta carry my guns very-very nice! Couple months time, I guess we'll see just-how-well for sure*
Also fwiw, should any of you paying attention and showing any interest in taking something like this on yourselves.. you'll see I stitched the seams with leather lacing rather than thread/machine sewing. I haven't got a machine myself for sewing, nor do I really believe thread will last any-longer than a leather lace... those laces are banjo-tight and not going anywheres! I treated (and will be giving a few more coats) with neatsfoot-oil.. I'm quite certain the "3/8" lacing (I cut it thick, is moose hide) SHOULD last as long as the scabbard it-self... I'm hoping* ...time will tell though
See what you see.. thought some of ya'll would be interested in how it went**
...should mention, the scabbard actually has length enough for a 29-30" barrel.. depending on the rifles-action and whether long or short. The brake (on mine anyway) is 2" long, making that 26 a 28" There's probably a good 3" to spare for room.
