1984, To be honest, I only checked the speed on a couple loads.. The 140 gr. Sierra HPBT is about 3000.. I started with that, 140 SST's and 110 gr. Sierra for varmints.. The SST's didn't group quite as well as the Sierra's, so they have just remained on the shelf.. But I did kill a cow elk, and buck antelope with them.. Mostly I have shot the Sierra's.. Killed several deer and coyotes with them out to about 400 yards+...
I plan to try some 130's this summer and later either 150's or 160's..The trouble is this 140 gr. Sierra and H4831 just works!!! I shot I4350 with the 110's, but a friend gave me a 3# coffee can full of original H4831.. Loaded a few for accuracy, and off we went.. Life should always be so simple..
