Bobin, I never 'over spun' any bullets, well save PERHAPS one time when a 70TNT may have POOFED on the way to a 330 yd target, SWORE I fired 5 but only 4 holes, 6BR @3400... and yes, 8 twist.

Never had poor accuracy going fast/faster RPMs, but not needed the last 1% of accuracy b/c I am not shooting for score, as hunting is my game, and game is the target. The rest is practice and fun.

Yes, I heard some folks were playing w/the 270 in higher weights using faster twist, preferably - no doubt it will make for ONE Fine LR rifle round!

When folks really want to Stretch w/Reach, little substitute for more BC and momentum...so heavier bullets rule, typically longer, and need some Twist/added.

I can imagine a 270 quick twisted using heavies, in say a 24 or maybe btr yet 25-26" tube, and go ahead and do an AI on it.

That should really shake things up. Alas, 280AI and 180s...Lol.

Aussie, always enjoy your posts, and folks like Dom across the pond. Nothing trumps experience, nice to share info on the fire.
