I was hoping someone has some experience with this cartridge - 270-308 ackley improved. Ackley mentions it to be very efficient, curious to know if the velocities meet or exceed those of the 270Win. Heck maybe 7mm would be better for hunting.

Might be a nice short action, light weight 270!

Why not a 270WSM?, better than 270 ballistics and a factory round too. Better resale value if you sell it later and cheap dies.

I have one, in the form of a Shilen match SS barrel on a Savage 110 action. I haven't played around with it any, and in fact I am going to sell it.

Your right. Its supposed to be equivalent with less powder, recoil etc. I don't know all the details on the 270WSM but I suspect barrel life will be better in the 270/308 Ackley improved and accuracy may be better. The Tikka M55 bolt face is probably too small for the WSM. Also the clip is fairly narrow and I doubt the fat WSM would work.

Tikka M55 rifles are supposed to be about 6.5lbs - with a wood stock. The 270/308AI would fit nicely in a compact lightweight rifle.

Perhaps the 7mm-08 Rem is the way to go. Way too much reading to do.....................

try a 260 Rem
