I have both. When I really want to work on my accuracy skills I use bolt. It requires more time and concentration. Those same skills transfer over to my very accurate semi. I also reload my ammo to (best I can) comparable to match grade or better ammo. The bolt guns also range time from minutes to hours. With my semis I never get to the fatigued state that affects my shooting. With the bolt guns I get much more of a workout. With a box of 50 reloads the bolt gun can manage a couple of hours at the range. The semis can burn that amount in half the time or less. My greatest skill advances come from the bolt guns, not the semis. That skill transfers to the semis though. I showed this once with my Ar hitting 10 head shots in a row at 500 yards with what I call slow rapid fire. I find it harder to advance my skills on a semi than transfer them to the semi from the bolt.
