Been reading up on the 300 Win Short Magnum. It looks like one of the Bench Rest cartridges in 30 cal. Should give atleast .30-06 ballistics out of the 15" barrel. Hmmm, starting to think it might be a good round for elk in an Encore. Scoped up and not too far away of course. Hmmmmm, never can tell. Slim

I have good luck with my Encore 15" 35 Whelen traveling 2100fps. with a Hornady 250gr. round nose. You can get a 15" barrel in a 416 and 458 Ultra mag. from Arthur Brown. The only thing you need is the arm to hold it down to keep it off your forehead. Mark

I shot a Contender in 40/70 with a muzzle break I can push a 300gr bullet at 1997fps and this is a hand full. I think this 300 Win Short Magnum in a Encore would not be a joy to shot. For the big boy I when with a Competitor I have a 375 JRS MAG with a 16" bbl with a muzzle break and this gun is fun to shot even with a 300gr bullet I can shot 40 rounds and walk away with no pain from it.
The 300gr bullet at over 2600fps and over 4000 energy

i have a 15'' encore barrel in 300 win mag.its got a jp muzzle brake. i talked to e arthur brown and they dont like to go over 300 win mag because cant get good powder burn.i would like a 7 stw for my encore.if you deside to get one let me know how it shoots. jason
