White Model 98 Elite Hunter in .451 caliber. RWS #11 cap, 100 grains Pyrodex P, 426 grain home cast conical. 200 yards on a feeding doe. Shot was taken from one hillside to the next, laying angled on a slightly downward slope in the prone position. No wind. DOA
I had practiced at longer ranges up to 220 yards that summer and early fall with the intention of pulling off such a shot just to prove I could do it.

Because of the practice, I had complete confidence in the rifle and the holdover required for such a shot.
I'll probably never try that again.
