I have a 1 10 twist on my 338-378imp. Still havent got to shoot any bullets out of it to tell if it will stabilize them.

Yes they use 10 twist. When the bullet speed passes 3200fps (300MK) then you can go to 11" but 10 will work across the spectrum.

Sierra recomends a 10 twist for this bullet.

i've heard of a couple competition shooters that are using an 11.5 and not shooting them all that fast. for any hunting gun that has an edge chambering,a 10 will probably serve you best.

I use a 1-10 twist in all the ones I build.

I use 1-10s in all my big 338s as well. I have never seen a problem with accuracy from the 338 Win Mag up to the 338 AM.

In some instances there may be some more appropriate twist rates but as of yet with this range of chamberings I have not found one.
