Ballistic Coefficient Question

[Soggy Bottom]

I'm looking at getting a rifle built for my wife this year. I'm looking at the 6mm Remington or the 25-06. My question is why there is such a difference in the ballistic coefficient in the two rounds. The way I understand it BC is the wind drag on a bullet that gives you the BC number. Wouldn't that be more influenced by the shape of the bullet and not the caliber? Than I thought about having the best of both worlds and going with the 6mm-06. I have 25-06 that I love to shoot and but do not see that caliber ever listed on any long range forums or long range cartridge list. The 6mm comes up all the time in the long range world it seems like. Any input would be appreciated.

I could be wrong, but the twist rates for the 25-06 are not fast enough to stabilize a heavy for caliber bullet. The long range crowd is the group chiefly responsible for high B.C. bullets.

The 6mm bullets come in much higher B.C. bullets b/c there is a plethora of fast twist rifles that will stabilize the heavy for caliber bullets.

I'm sure someone else will chime in and provide a more detailed response.

The reason behind not seeing anyone talk about 25-06 for long range is the lack of high bc bullets.

I'd pick the .25/06 out of those two. In fact, if there were two "ideal" hunting calibers for most of the USA, the 7mm/08 and the .25/06 would be top contenders. Plenty of others, of course, but for sufficient killing power at sensible hunting ranges and availability of factory ammunition and reloading components, along with moderate recoil those among the best. I wouldn't worry about what people use to punch targets at extreme distances too much when choosing a hunting rifle.

6mm Remington is one of my favorites. If you reload there are tons of options for it. Great choice!

Ditto on the 6mm Remington. I don't have one, but I sure do WANT one!

What brass is available for 6mm Remington?

I see Midway and Brownells sells brass in Remington, Winchester, and Hornady for the 6mm Remington.
