Hodgdon's own data says 2690fps with a max load of 45gr, and you're going to lose ~80-100 FPS from going to 20". If we revise the number to ~2550fps, yes, that's believable. The OP has a bigger problem, which is that he's gonna have to fight some velocity loss from being a semi-auto, too.

(And before people jump on me over 50fps being negligible, if you're using one of the many BDC scopes out there calibrated to 175gr SMKs @ 2600fps, it's not a negligible difference at longer ranges.)
I think you quoted the wrong post. I am getting 2600 out of 24" That is what my Oehler chrono says I am getting.

And Ballistic AE gives me good dial ins based on that velocity.

I shoot 175 SMK, 43.5 grain Varget, in Lapua brass, and get 2600 out of 24"

Just saying.

I don't know if 4.35 grains of Varget will push the bullet out of the barrel.
Are you sure that you aren't loading 43.5 grains of Varget?
