I've had a 256 Win Mag on a 92 Winchester since mid-1960's and had a 256 10" barrel on a contender. The largest animal I've shot at was a red fox. I'd be interested in your findings. The Winchester shot the factory ammo very well. The other bullet I shot a lot was a 60 gr Hornady flat point designed for the 25-20. I've also shot at targets with a Speer 75 grain flat point bullets. I've not been able to shoot much longer bullets accurately - due to twist rate, I suspect. 87 grain Hornady bullets shot about a 4" group at 40 yards and the bullet holes looked like the bullets went sideways.
