Velocity with 777 pellets and Barnes TMZ

wwwboaringdotcom · Aug 21, 2006

I don't own a chronograph and wanted to see if anyone had an idea of the muzzle velocity of the following combination:

T/C Omega shooting a 250 gr Barnes TMZ backed by 2-777 pellets

I'm trying to figure out the trajectory of the load out to 150 yards, but I can only guess the velocity is around 1850 fps.

Any insight would be greatly appreciated.

Thanks

The velocity should be aprox. equal to that produced by 2 pyrodex pellets, so if you can find a ballistics chart that lists pyrodex, use that. The loose 777 is 15% stronger than pyrodex, but the pellets are supposed to be equal.

Sorry, I shoot 3 Triple 7 pellets out of my Encore Pro Hunter with the 250 grain Barnes TMZ. My average muzzle velocity is 2225 fps 10 ft in front of the barrel.

Its not alot of fun crono'ing ML loads... I bought blast shields for mine and it still takes me an hour afterwards to clean it up LOL.

I'd have to go check my notes but I think I was in the 1850's for FPS with Hornady 240grn XTPs on 120grns Pyrodex. Whats your barrel length?
