I have a Weatherby 240 with a 1 in 10 twist. Was wondering if I would be pushing the 105 grain fast enough to stabilize them? The Berger chart says 1 in 8 twist, but was wondering with the added speed of the Weatherby would shoot them?

Only way to know is to try. Remember just cuz they are stabilized at 100m doesnt mean they will be at 500m...

You may be right. I have two 6.5 calibers, a Creedmoor and a 6.5X284 Norma. The Creedmoor with slower velocity has 1-8 twist while the 6.5X284 has 1-9 twist. The 140 Bergers supposedly should have a 1-8 twist, but both rifles stabilize them, and the 140 Amax. The added velocity of the 6.5X284 has to be why they stabilize with a 1-9 twist. I don't know what the twist rate is, but the new 264 Win Mags also stabilize the 140 Berger VLDs. I would think the Weatherby would stabilize the 105 bullets.

I shoot the 105's out of an 8 twist 243 and they are super accurate. When it comes to stabilization there is no hard and fast rule some guns will shoot them and some wont. Added velocity may help but you may find that your barrel may be slightly faster or slower than what is stated by the book. Give em a shot and see what happens.
