Looks similar to a 435218. Are the bands tapered?
Looks like an NEI SSK-style 310gr.
It is definitely the 310 SSK. They call it a 310, presumably that is what it weights in linotype. In COWW they are closer to 325 gr. Mine has a slight taper. .432" at the base, and .429" at the top band. It's probably a manufacturing defect more than on purpose. I like this bullet a lot, it shoots good with less than full house loads.
There is a 355gr gas check version. This one is the 310 version, plain base.
I have this one and had Mountain Molds make me one in .452 and a wider meplat. With 17 gr 2400 my SBH loves it.

I shot many of these backed with 21.5 grains W296 and CCI 350 in Ruger SBH 4 5/8th gun. Fun to do.
Seems this question has come up before;
