Stocks, like everything are a series of compromises. In general a stock specifically optimized for offhand shooting will be compromised for prone in some way. Same in reverse. So there is a balance that has to be achieved. For field shooting (western hunting) recoil control/muzzle control from prone/sitting/kneeling/standing are all important, with them listed in about the order of importance. So too is comfort carrying in hand, flexibility in compromised positions and rests, weight, etc.
There are multitudes of stocks available with flat foreneds, Arca/pic rails, adjustable cheek pieces, etc. There are no stocks for Tikka’s that take a normal sporting stock and optimizes the geometry and design for correct shooting and control.
