You called, citizen?
Anyway... :yup:
It all depends on the perfectness of the bore. According to the math, if the spin is not jerky at all, a perfectly flat plane is the best 'barrel'. However, this is not always the case. Therefore, depending on your hop system, different barrel sizes are appropriate. In a normal hop system, 6.03s are good because they guide the bb, but still provide a wide enough bore so that the bb bounces less. In theory, with an ER-hop, a larger bore, like 6.05 would be better. This doesn't always pan out, mostly because 6.05-6.08 have kinda crappy bore quality (in general) for some reason. There are exceptions, but they are stainless steel and a royal PITA to machine. :shrug:
Basically, the best bore (most consistent) is in barrels of diameter 6.01 and 6.03 (I guess because of tolerances?), but a 6.01 is too tight, so a 6.03 is best (realistically, not theoretically).
I use 6.03 madbull black python and prometheus (those are really the only two barrels I ever use) and I just got my M24 shooting 7 inch groups at 121 meters (prometheus barrel, stock length). Not to worry, it is at about 600 fps and I am using steel bbs, so no skirmishing with it, I am afraid. Not to mention trigger pull is a bitch...
I just noticed - 1500th post! Woot!
