Hey guys, I recently upgraded my Well MB4410 and now it pushes a little past 500 with .25s. I've been using .36 bios from Valken but I'm done with them. Their .28s are actually decent because that's what I use in my aeg's but I can't use their heavier stuff, it's awful. I know it's not the sniper that's shitty because I can use the .28s and it's pretty accurate and rarely ever any flyers, I just don't want to hurt somebody with it shooting that fast. My field is bio only, Power Ops Airsoft in Atlanta, and they sell the HPA brand there. Does anybody have anything good to say about them? Trying to use .40s or .43s and if you have suggestions for any other brands then please let me know.
