30-06...168gr ballistic silver tip over 50 grains of varget...

lets say its a typical day at 72degrees F, at sealevel, with a 20 inch barrel....what kind of velocity do you think we are looking at here?

“For once you have tasted flight you will walk the earth with your eyes turned skywards, for there you have been and there you will long to return". -- Leonardo DaVinci 1452-1519

"The rifle itself has no moral stature, since it has no will of its own. Naturally, it may be used by evil men for evil purposes, but there are more good men than evil, and while the latter cannot be persuaded to the path of righteousness by propaganda, they can certainly be corrected by good men with rifles."
Jeff Cooper, The Art of the Rifle

The online Hodgdon data says 50.5 gr of Varget under a 168 gr Hornady BTHP in a 24" barrel is 2859 fps with 49,200 CUP. I'd guess about 2700 fps. I haven't ever used Varget so it's just a guess.

Maybe 2800 is a better guess. Rifles are individuals the results can vary quite a bit with a load.

keep in mind that individual rifles can vary considerably from 'published' data. some as much as 20%. (only your coronograph knows for sure)

A lot of guess-work involved in this answer, but a guess is what you're asking for, so here goes: I haven't used Varget in .30/06, either but have used a LOT of IMR4895. Hodgdon data indicates the burn rate of IMR4895 & Varget are very similar. I also have some .30/06 short barreled rifles. I do a lot of shooting over chronographs. After checking my notes, my best guess would be 2650 fps or there abouts. I'll check your load in a 20" .30/06 one of these days, but by then your post will have been long gone.

With "pretty good" self contained chronographs costing around $100, there's really no need for guess work.
