guess I should have mentioned that I'm using the H4831sc. I don't think I've ever seen the old H4831 for sale, although I had an old can of it back when I first started reloading 15 or so yrs ago.
as an aside, I did chronograph the 59.0 g. h4831sc, 130 g. hornady spirepoint load out of a ruger m77 mkII (22" barrel) several years back. I was a little surprised to be getting just over 3000 fps, figured I would need to go to 60.0 g. to get that kind of velocity. But, this was in the middle of the summer, temperature was in the low to mid 90's. I decided at the time that was the explanation.
have not chronographed the load out of the sendero's 26 inch tube, but i have to think that it'd be moving a little quicker.
Higbean, thanks for the link.
