Have you bothered to shoot the bullets to see if they actually will shoot in a 1-10 twist or are you just giving up from reading on the box?
My recommended standard twist for the 6-284 with 105 gr Bergers is a 1-10.
I am not saying the 1-10 will shoot the 95 gr well but it would not surprise me if they shot very well. In fact, with the berger bullets, the very least amount of twist you can get away with, the better as far as allowing you fine accuracy with top end performance, especially when you have a chambering capable of +3300 fps with a given bullet weight which you certainly do have.
If you were shooting them in a 6mm BR, I would say yes, a 1-9 would be recommended. Berger has to recommend a twist that will work for ALL 6mm chamberings. You have one of the largest 6mms out there and as such you have the ability to drive these bullets MUCH faster then the average 6mm chambering.
Load them up, push them up to the upper limits of the chambering and I would be suprised if they did not stay on point. If they shoot accurately will depend on many things, namely the rifle and the specific barrel and rifling design.
I wouldnot give up so soon without putting bullets in the air, that would be unwise.
