'409,
Bullet "weight" is largely moot,though COAL,integrity and BC ain't. Hint.
The 300 Wby will simply run you out of mag confines,precluding the best of that which is available projectile wise,long before a 300 Winny on a 700 receiver. Pardon my being fluent in said matters,as you gals guess aloud. Hint.
Fhuqking LAUGHING!................
I get it.
In matters where every last decimal place in the equation count.......... .300 Win Mag for the win. In matters of 99% of Joe 6-pack's 0-500 yard hunting rifle, the .300 Wby just thumps a little harder. Is it worth the extra 10-15 grains of powder ?? Is it worth the extra recoil ?? Meh........... To me, it probably is.
That being said.............. I load for 7 .300 Win's and only 1 .300 Wby. And if I were going to grab a rifle to go kill something smaller than a coastal brown, right this instant............. I'd grab a 7-STW over either .300
