Re: 257 Wby vs. 264 Win Mag

I forgot to add, you will need an "8 twist" barrel in the 264 with the heavier bullets to make them perform well.
Don't go with a 9 or 10 twist like the factory did.
A 9 twist seems to only stabilize and accuratly shoot bullets with a weight "UP TO 129 or 130 gr."

8 twist in the magnum 6.5s will perform extremely well.

Re: 257 Wby vs. 264 Win Mag

The first time I saw a 200 score on the 1000 yard line, it was shot with a 26" 1:8.5" twist 264 winmag with a long throat. He used 155gr SMK's and shot a 200 - 11X. Since then, I've seen three more 200 scores shot using 6.5x284's and 142SMK's, two of them just last Sunday. With the 142SMK, the 264winmag easily got 2950fps without any pressure, and would be my choice hands down.

Would a 264 Win Mag Rem 700 with a factory 26" barrel be worth my time?

Re: 257 Wby vs. 264 Win Mag

If you only want to shoot bullets up to 120 to 130 grs (max) it would.

The better bullets start at 140 gr and go UP from there.

The 9 and 10 twists in the factory barrels do not stabilize the heavier bullets well. The accuracy is terrable in any I have seen except for lower weight bullets shot in them.
You need an "8 twist" in the 6.5 for the 140 to 155gr bullets for longrange hunting/shooting. That twist seems to work the best.

You can always rebarrel later after you shoot the lighter bullets in the factory rifle you mentioned?

Re: 257 Wby vs. 264 Win Mag

Im a fan of the 257. Ive shot 5 bull elk, ? cow elk, lots of mule deer and 3 whitetails( barnes bullet went through the buck and killed the doe 15yds behind him) a 22 with good shot placement kills just as much.
264=better bc bullets
257=higher velocities flatter shooting
