Tikka 300WM - want longer OAL
Looking to the brain trust of the board, hoping I've missed something.
I'm working with a Tikka Tactical 300 Win Mag in a Manners T4 stock. Load development indicates a longer OAL would be beneficial. My goal is whatever that length turns out to be, is capable of feeding from the magazine.
Research indicates this to be a common hurdle, for which I have yet to locate a solution.
Aftermarket bottom metal for the Tikka long action is limited to CDI as far as I can find. While this allows the use of AI mags, it doesn't help with OAL increases beyond the factory Tikka set up due to internal design limitations. No fault of CDI, but perhaps potential to expand on the offering if possible. The challenge as I understand it is, there's not much room to move the magazine back as it will quickly interfere with the trigger.
Users of short actions have been successful in working with longer OALs by modifying the bolt stop to long action specs, thus allowing the bolt to move further rearward and pick up the fresh cartridge. This works because the short action has room to move further rearward.
Has anyone, with greater knowledge than I, explored the potential for a similar modification for long actions? Is there enough room to be gained as to make the effort worthwhile?
A thread on another board indicated Dave Kiff was looking in to developing a DBM that would address exactly this, but that thread has gone silent for almost a year now.
Beyond that, has anyone come up with anything I've missed? I believe this rifle has potential but is being held back by this limitation.
