A somewhat older thread that I dug up because I think one thing that's important, but was not mentioned, is the fact that bullet weight can "sometimes" describe a round.
In saying that I'm thinking;
.270 Win. with it's 130gr bullet.
7x57 with it's 175gr bullet.
30-06 with it's 180gr bullet.
45-70 with it's 405gr bullet
And, the .35 Whelen with it's 250gr bullet.
These weights "seem to be" the weights that first stirred interest in these rounds for hunting purposes, and perhaps that is as it should be.
I'm sure there are many others, and the weights I listed can be substituted with your own favorite weight in any caliber....still yet, when we speak of a .35 Whelen I personally feel we are also saying 250gr, with very few exceptions.
I have played around with all the weights, plus casting some rather odd but interesting weights....including Lyman's 358009 at 282gr, and I feel the 250gr best describes the .35 Whelen.
