My deer load in my Black Diamond XR is 70gr of 3f Swiss under a 250gr .45 cal Hornady XTP in a Harvester crush rib sabot, lit with a musket cap.Velocity is 1550 fps, drop at 150 yards is 8 inches and 22 inches at 200( confirmed not guessed). The 250 XTP is the non-magnum version and is perfect for this velocity. Recoil is mild , which cannot be said for its terminal performance! Back in August I made a 150 yard neck shot on a nice doe and the damage was impressive. With the shorter barrel of your LK93 ( the XR has a 26 inch tube) your velocity might be 100fps or so less. Another 10 grains of powder should make up for it. I have found black powder, specifically Swiss, to be the most accurate propellant in my rifle. Its very consistent in terms of velocity( it a bad day when shot to shot variations get higher than 15 fps) and as you'll be swabbing between shots, fouling is a non-issue. My bear load is the non-mag 300 gr 45 XTP in a crush rib sabot over 90gr of 3f Swiss. 1600 fps and roughly MOA accuracy. the 250/70 load is consistently sub 2 inches for 3 at 100.
