If you want the data, go out and get it. Can't expect everyone to hand everything to you.
Comparing my rifles would only tell you about my rifles and the ammunition I shot in them. There are bolt guns that don't shoot anywhere near as well as they should and some semi's that exceed expectations. I guess its nice to see a sample size of 1 but it won't really tell you anything.
Yes a bolt should be and usually is more accurate than a semi but not always. Depends on so many factors and every rifle is different so even if I can show you my results it doesn't mean you'll see the same thing.
I don't have a nice bolt 22 but I do have a few nice semi's.
If you buy a semi will it shoot like a bolt gun? ... who knows, maybe not
If you buy a bolt gun will it? Probably but who knows.
This style of shooting there are trade offs and only you can decide which is more important. Personally, the way things currently are, I can see how a semi is advantageous if it shoots well enough and I believe some certainly can. Usually it isn't the gun....
Dlask DAR 22 w/12.5" barrel at 50 yards, 10 shot groups on a calm day.
Shoots CCI SV at 1060 ish
Might be more consistent at longer ranges with better ammo but CCI is good enough for me. I can hit a 12" plate at 300 more often than not, wind depending lol.
