Re: 257 weatherby long range whitetails
I measured them and used a BC calculator that works off of simple forms and weights to get a G1.
I have only done a limited amount of testing with the 130 grain bullet out to 1000 yards and there is conflicting information. I am not willing to post a BC based upon the data I presently have. Suffice to say it is better than anything on the market even if I am off by a significant amount.
My opinion is that it will kill really big mule deer out to about 1200 to 1300 yards. I should be able to kill elk out to 800 with ease even when having to break shoulder bones. That is the benefit of shooting high BC heavy bullets real fast.
