muzzle engergy isnt so important, but a heavy projectile will retain its energy longer, more momentum

That's why I said it was a terror, not terrible. They worked well with the high ROF. I also have some lower FPS guns that can't shoot a heavier round well like 0.28,0.30, etc. although hop-up, air seal, and barrel give you BB stability, you need a certain amount of punch to sustain flight. In extreme CQB (50' engagement distances or less), is stick with a 0.25.

I use .20's in my grenades. Other then that I use .25's or occasionally .28's in everything else.

I suppose that could be done. Personally, I recycle mag leftovers, end clipping from used bags and floorfallen BBs for nades and claymore mines. .20g is just what I use for chrono standard.

Nope I like my .30's and higher for both AEG's and Sniper guns

.2s are shit outdoors in my opinion i never use them unless its indoors for CQB since the wind is a serious issue whilst playing outdoors with ,2s

dont forget some BBs below .28g will have bubbles, and those are never centered.
When you get your hop set as flat as it'll go and you see your BBs do that random banana peel out at the end of your range, that's not wind. That's the BB destabilizing and rolling in a random direction. It also means you need to be running heavier ammo to eliminate that peel out :)

shush you! :D

Umm... All BB's have bubbles in them to a lesser or greater degree, that's part of the manufacturing process. One of the prime differences between a well made BB (BB Bastard) and a crap BB (Canadian Tire or Walmart brand) is that in a well made BB the bubble is always centered, and in the crap BB they can, and usually are, off-center, causing the BB to fly in weird flight paths regardless of wind or cover. This isn't really an issue of weight but of quality.
