I've had two of them and three .25-06s and three .257 Roberts. All I use nowadays is a M-70 .257 Roberts for deer and antelope. For elk and such I still want the heavier 180-200 grain bullets but the .257 Roberts is as good as any of the faster .257s and lighter to carry.

I'm not at all poo pooing the .257 Weatherby...it's a fine cartridge and in the Vanguard it's even better. However you'll not know the difference between that rifle and the .257 Roberts.

That may be hard to swallow but it's my experience. Faster is better.....at least on paper it is...in the field the bullcrap gets lost and what happens is that we often discover that the extra is lost to something we're not sure about.

Simply.....very few of us are able to use the difference to advantage.
