I don't remember the vintage on this old '99, but it was a blast working up loads for her. I finally settled on a 100gr. Speer soft point and H4895. It would hold 1 MOA all the way out to 300 yards - never tested it any farther than the 315 that I took this antelope at!
I sold that rifle for $650 just the way you see it in the photo. But I found that I really didn't want to do without, so I bought another '99 in 250 Savage a couple of years ago, and I'm a happy camper!
By the way, I tried 4 or 5 100gr. bullets before I found the Speer. They all hit the target at varying degrees of sideways. The Speer is almost a round nose, and has a flat base, so the overall length is shorter than any of the others. I think that is the key Vs. weight - just make sure it is short enough for the 1 in 14 twist to stabilize.
