Robert, your description of the bullet does not match anything that Berger has on their website.
So do you mean "95 gr Match Grade Classic Hunter" part # 24570 ? 6mm 95 Grain Match Classic Hunter
Because if it is not that bullet you are unlikely to have success with any of the other 95 grainers in your 1:10 twist barrel.
I tried the "95 gr Match Grade VLD Hunting #24527" in my Savage 12 26" 1:9.25 barrel and they would not group better than 2" at 100 yards. I ran the calculation on the Berger website http://www.bergerbullets.com/litz/TwistRuleAlt.php
and it confirmed the stability problem because of my twist rate. If you are shooting at much higher ambient temperatures and higher elevation (my parameters are 20F and 1000' asl) then your result may be better.
In the meantime I have a new Shilen 26" 1:8 chambered in 243 AI and it shoots the 95gr VLD's in 1/2" at 100 yards, capable of better since 2 of the 3 were touching and that is not even with a final load, thats while fireforming brass to the AI chamber. It will also shoot the 105gr VLD's and it sounds like it will shoot the 115gr DTAC bullets also. But the BC of the DTAC is close to the 105gr VLD so I might stick to the lighter one for now.
If you can shoot these bullets with a decent jump to the lands, it is better. First of all, it is safer for the case that you may need to unchamber a round after an unsuccessful hunt and leaving a bullet stuck in the barrel and the action full of powder is not a good thing. Particularly if you need to shoot a few seconds later and didn't realize the bullet was still in the bore... Secondly, having a bullet make a jump to the lands will lower your peak pressures and potentially allow higher max loads with less sensitivity. Max loads with bullets jammed into the lands could be far more sensitive to ambient temperature.
So specialized shooting sports like Benchrest may demand such a load configuration, but in general, one wants to avoid jamming the bullet into the lands under normal hunting conditions if at all possible. For berger bullets, jamming is a less reliable way to get repeatable loads and jumping is more consistent and today the recommended approach.
