will try if naay time, you based it sa ila ammunition size, like 5.56 and 7.62 are considered small caliber and .50 cal is considered large caliber, and above it is considered cannon...
to categorize the sniper rifle from SemiAuto to BoltAction is based from the rifle operation....
a weapon considered Semi Auto can operate without pulling the bolt to chamber a round or extract a round.. and bolt action is the opposite, you pull the bolt to load and extract a round...
its like this (sample lang):

- Semi Automatic
- SR-25/M110 (7.62)
- M21/M25 (7.62)
- Dragunov (7.62)

- Bolt-Action
- M24/M40/M700 (7.62/.338 )
