I can't believe this thread keeps going on and on and on....
According to one rule-of-thumb about internal ballistics (proven both theoretically and empirically) here's about a 2% difference in potential muzzle velocity between the .300 Winchester and Weatherby. That's about 65 fps with typical 180-grain handloads. Wow!
76grs of RL-22 gets me to 3085-3100 in my 26" Sako 300 Winchester. 80gr of the same gets me right at 3250 in my 300 Weatherby. While I prefer the Weatherby, the Win Mag is the more logical choice.
Not trying to be a smart a$$ jorge, but where is the logic? 40.78 fps/grn, 92 rds per/pnd, with the Win
3100, 40.625 fps/grn, 87rds per/pnd, with the Bee
3250. 150-185fps gain for 5 rounds? Not much to make any difference to me.
Thanks.
