Hi, intend to build a switch barrel rifle for hunting and target shooting. Caliber of choice is 308. Now, I have two actions that I can build on: Remington 700s and Tikka T3. I am not concern about the short hunting barrel but am concerned as to how long and heavy a barrel I can hang over the above mentioned actions? Standard Palma profile is my choice and barrel length as long as possible, upto 32". Would any of the action mentioned above be able to take the weight. Both are repeaters. Thanks for advising.
