Do not have chronograph available, hopefully someone shoots this load.

tulip,
An estimate from Quickload is 3307 fps (1008m/s) if the COAL is 2.93" (74.37 mm). Chamber pressure 47,879psi (3301 bar). To get a more accurate estimate one needs the exact COAL you use and H2O capacity of the brass. It is only an estimate.

Thnxs for the estimate. I do not know the exact COAL and H2O capacity of the brass. I'm not a reloader myself, I let it done by a gunsmith who does a lot of reloading. Its Lapua brass.

Not being funny, but the gunsmith who is reloading your ammo should know!

I've checked, his estimate ranges 2900-3100fps.

I was hoping some shooting the same parameters.

I've to go to a shooting range with one who has a chronometer to know exact speed.

I never had a 6MMBR V-Max blow up right out of the muzzle, but I did have one explode when it hit a staple holding an old target, under my target. It looked like a small hand grenade went off on the back side of my target, black streaks and lots of cuts in the paper (from the copper I guess), all radiating out from the center hole. Not sure how fast it was moving, (but 3000+?) the barrel is a 1 in 8.
