750 gr full bore 12 gauge slug

[gvanzeggelaar]

I am getting a mold made by accurate molds for my bolt action savage slug gun. Does anyone know what kind of velocities one can expect with this weight slug?

Thanks

No clue but my 3" brenneke gold 600gr slugs chronoed at 1320fps.

So maybe 1200 ish

I'd bet 1050ish at least. Recoil at 1200 would be fun. What powder would you use? 34grains of hs6 or blue dot?
