dependant on what velocity you are running you will then run a heavier bb and itll sort of even itself out. If you are runing 450fps or less on a .20 .36 or lighter.
Is this under the assumption that the shooter is utilizing a 6.03 tightbore barrel? I would like my rifle to be shooting around the 450FPS mark, but I want to invest in a PDI 6.05 430mm tightbore barrel, so would it be optimal to use slightly heavier BBs (like 0.40g) to better balance the ratio (since the bore tightness would be a modicum bigger)?

Speaking from experience, i used a 430mm laylax 6.03 with .30s on a pdi cylinder set and it was dead silent without an air brake.
Would it be obsolete to add an air brake (or to fill the stock with foam for that matter) if you've matched the volume ratios between these two components? I want the quietest sniper rifle possible, but I don't want to do more work than is necessary to achieve this goal.

Thank you,
EJ
