Good to see you chime in.
Yeah, I guess yall are right...However I did a home-made ballistics comparrison chart using ALL 4 calibers, with their bullet weights & types, that I am interested in...
Here are the results:
1.) .257 Wby. / 110gr. AccuBond - M.V.: 3,460 / M.E.: 2,950
2.) 7mm Rem. Mag. / 160gr. Barnes Triple-Shock X - M.V.: 2,940 / M.E.: 3,071
3.) 7mmSTW / 160gr. AccuBond - M.V.: 3,100 / M.E.: 3,414
4.) .30-378 Wby. / 180gr. Barnes Triple-Shock X - M.V.: 3,360 / M.E.: 4,513
These are the results I found.
If you look closely...the .257 Wby is NOT that much faster, nor is it that far behind on its energy, than the 7mm Rem. Mag.
I used to shoot a 7mm Rem Mag. for a LONG time...it's still one of my all-time favorite calibers!
So, why not get better ballistics, with virtually the same energy?
I was just saying that I AM getting a .257 Wby. Accumark for Whitties this year...however, I was asking is it possible for anyone to put a larger grain bullet in there...somewhere around 140gr.???
Don't you think that would be a deer killing machine!!!???
A .257 Wby. firing a 140gr. Barnes TSX!!!
