For decades the factories claimed 3,480 ft/sec for the 110-grain '06 load, from a 26" barrel.
The Sierra Spitzer bullets have a bit thicker jacket than the boat-tails, particularly in the 150- and 165-grain weights. I've had the 150-grain SPBTs blow up at close range. I wouldn't expect this with either shape in the 180-grain.
For a close-range varmint load, swage the .32-20 80-grain flat-nose down to .308 and load max. It's very much like a tiny hand-grenade.
