Could i just change out the barrel? it seems like that's about the only difference. the bolt isn't going to matter that much it just pushes the pellet in. I could get .30 mags for a different gun but it would be the same size on the outside.
You may or may not run into several problems potentially. The pellet probe usually is sized to fit the lead in of the specific caliber barrel and assuming a PCP it's generally going to have either an oring/seal on the probe itself or just inside the breech of the barrel which mates to the probe to seal air from escaping out the breach. Generally speaking most air rifles also have different air porting setups as well between calibers, not always but if there is you would see a very noticeable loss or lack in power going up without enlarging said ports. You may also end up needing to rework hammer and hammer springs and/or poppets. Just some things to check into.
@awilde I know they make a .30 bullpup blitz so similar parts have to exist somewhere. It's not available in America but it may be possible to get the part from a regular Blitz and as long as i have all the trigger linkage for my Bullmaster to make it work. i need to search for a gunsmith that works on PCP airguns I guess.
