Hello I have an m3 currently with 600mm 25 cal barrel. I am currently shooting 25.39 and hades pellets with a second reg pressure of 82 bar. The 25.39 are 890-895 and hades 875-880. Thinking of getting a 30 cal 600 mm barrel and looking for a good reg pressure to begin a 44.75 pellet tune ? Only really interested in ever shooting 44.75 out of it. Looking for 875-900 for speed. If anyone can share a 44.75 tune that would be great. I have a non power block stock internal gun. Thank you.
