The 1-10" twist probably won't be fast enough to stabilize those 115gr solid copper bullets if they're the longer VLD-style. Copper is lighter than lead, so even though a 1-10" twist will easily stabilize most conventional copper cup/lead core bullets, a solid copper bullet of the same weight will be noticeably longer and require a faster twist. You can cheat a little on twist rate if you push them fast enough, but the .250-3000 Savage, even in an Ackley Improved like I have, won't provide enough speed to help in that regard. A 25-06 or .25-06 AI maybe, but not a .250-3000 Savage or AI.

If I were wanting to build a .25 caliber to shoot the newer long/sleek bullets I'd probably go the .25-284 Norma route. The .25 Creedmoor has had some popularity in recent years, but I wouldn't recommend it on a Savage platform due to all the well documented feeding/extracting issues Savage's have with the Creedmoor cartridges.
