it's not that I myself "prefer" bolts (like pretty much all flavors), but do appreciate any well made bolt action
some invented "devices" are just inherently better re; fitness-for-function than others.. it's just that simple
if/when wanting or needing to throw a whole bunch downrange real fast at something or at somebody-trying-to-hurt-you-real-bad, the bolt action is obviously not "best by design"
but a great many riflemen place a premium on accuracy,
(after all, why would we/they NOT ???)
as fitness for function goes, and inherent design advantages for achieving best accuracy, no other action type can compete, absent must-go-fast criteria
a bolt action is about as simple as it gets, KISS, and there are strong arguments in favor of that simplicity even vs. the various flavor of single shots
"one piece" receiver/chamber/barrel made fron one piece of good (old fashioned) steel
fewer parts moving when fired than anything but a single shot "other", and no hinges, no variable alignment issues, faster lock time than any external hammer, easier to get close tolerances on head spacing than most anything else
if put the same "effort" into making one well as something "other", fewer variables too get just right, dollar for dollar, hour for hour
any/every action type can be made super accurate with enough time, attention, and money...
but it's just easier & cheaper to do with a bolt gun
and if done "as well as it can be done, as well as anybody knows how to do", no matter how rightly praised other actions are, those other designs are just not as easy to manufacture to pert-near-perfect as a bolt action
strength ?
say whatever you will about action type X, Y, or Z
if looking for strength, nothing else offers the inherent design advantage of the bolt action, can do
50 BMG
Olympic match grade rimfire or BR50 competition
50 yard, 100 yard, 300 yard, 1000 yard, or a mile, any caliber you want at range for caliber
loud or quiet, light or heavy, muzzle flash or "no" flash
you can have it in bolt actions, and have same performance for fewer dollars, or better performance for same dollars
inherent KISS design advantage, simplicity, fitness for function
absent need-for-speed, what's not to love ??
wrong color ?
(you can get 'em in black, too, you know)
