a 25cal 150gr bullet could be close to the same bc as a 180gr 284 bullet i think?
I think a 145 grain bullet with a B/C in the low sixes or very high fives at 3000 fps would be a serious long range round. The 140 grain Amax in 6.5 caliber has a B/C of .55, and the .257 would be a little better (maybe .57 B/C). More importantly is that you can seat the bullet on out into the freebore unless you have a no freebore chamber.
