1-10" twist will work great for that range of bullets up to 120 grains. You really have to decide if fireforming brass is something you are willing to do. The standard 25-06 has been know to stretch brass, but the ackley version stays put. The fire forming loads also shoot great so use them for normal plinking, and think of it as an upgrade when you get to load the improved version. Expect about 200 fps over the parent cartridge. I just measured one of my ackley rounds and it holds 70-71 grains of water.
85 grain nosler ballistic tips have been known to rip coyotes in half. 3800-3950 fps can be obtained with the 85 gr bullets. 100 gr expect 3500-3600 fps. Step up to the the 115 grain berger vld's and start plinkin away at 1000 yards. This is long range hunting right?
Pretty versatile if you ask me. Not saying the 25-06 won't get the job done, but the ackley will just do it a little better.
