Ken,
<br>
<br>I know that the term "overbore" gets applied to a number of rounds.
<br>However, if faster powders are used, doesn't that change a cartridge from "overbore" to "just right" or even "underbore" (if there is such a term)?
<br>
<br>
<br>This concerns a .257STW project I am involved with. I want to use 115gr. bullets at speeds higher than available with the .25-06 or .257Wby., say around 3400fps.
<br>
<br>It's important that pressures be kept down, if possible, as this round will be used in Africa and the American west during warm weather.
<br>
<br>I expect short barrel life, but that's okay, since this will be used on long-range predators, large varmints, and deer-sized game.
<br>
<br>If I have made any grossly inaccurate statements or assumptions, please set me straight.
<br>
<br>George


Shoot straight, shoot often, but by all means, use enough gun!
