I'm using an Echo-1 PSR with the following mods and upgrades
AA 430x6.03mm inner barrel
ML lever
ML 70° bucking
Fully sealed cylinder
507fps with .20 bbs
If I understand all the info correctly I should use 0.43g bbs because of my cylinder to barrel ratio, but the joule measure is not the one that I expected.
0.20g - 507fps - 2.38j
0.30g - 418fps - 2.42j
0.40g - 322fps - 1.92j
I don't have access to 0.43g bbs atm, but I've played with 0.30g, 0.32g and 0.40g, the best results so far are with 0.40g bbs, but I was expecting more joules with that bb weight. Should I buy 0.43g bbs and use those or should I stick with 0.40g? It's worth the joule drop from 0.30g to 0.40g or should I use 0.36-0.38g bbs to have more energy?
Is worth mentioning that I can overhop 0.40g bbs with my current setup.
Edit: I measured my BASR fps in the field last Sunday, with little to no time for hop up adjustment and 2-3 shots per bb weight, so the numbers might be off.
