Great lucky break right there.
I am reminded that at times, fortune can smile quite brightly. Your handload is right up there with factory ballistics. We used a couple different powders, but those 200 grain JFP's all clocked at or around 2200 fps. I read a brief by Brian Pearce a few years ago, where he had temporary custody of an almost N.I.B. 1886/33 WCF. I recall that he found the gun capable of sub-moa accuracy with factory loads. Ours was well used, and a little too tired to shoot that well, but the 33 accounted for all manner of big game and pests.
If I found a deal like yours, I would not think twice before picking it up!
