Queston, not sure if anyone has measured this, but
how much velocity (and consistency) is lost in a semi auto vs a bolt ?

I hacked up my beloved marlin 60 for my daughter, and was thinking if i get to replace it either another (or savage )

but thought a bolt might be more accurate, also it wouldn't hurt me to work a bolt action more. i recently got a 308 stevens 200. I am new(ish) to bolt cycling. While i have always had a single shot remington, i did all my hunting with a semi-auto 22, and a browning BLR (lever)..

anyway, back to the question, i know i'll loose some utility, but would i gain any accuracy or range ?
