Re: 300RUM vs 30-378

Remington 700 stainless synthetic off the shelf rifle. First group with it at 750 yards was a little over 4 inches. 225 nosler accubonds at 3264 fps with RE-25 powder. It is an excellent rifle and a great elk rifle. I do not know how much it weighs. My 338-378's shoot this bullet on average close to 3450 fps.

    I'm guessing your talking about a 338rum. Did you try to load up to see what it would do with out pressure signs?

    Very well said ! That is exactly what I plan to do. Not sure if I will burn my 300 barrel up first, or go ahead and rebarrel to .338 RUM.

    yes, it is a 338 ultramag. This is close to top velocity in this rifle. The barrel was cut to 25.5" when the brake was installed.

    How long is the barrel in your 338/378?

    Why did you have the barrel cut and not just threaded?
