Good plan, but can you see about a midweight BB in the meantime? 0.30g tends to be too light, 0.36g tends to be too heavy sometimes, but is largely an inconsistant variance (I recently posted some measurements of various BBs of the sniper variety, here it is, check out how bad they are):

ONLY A REFERENCE. YOUR MEASUREMENT WILL VARY.

first how i checked the size. random 10 bbs out of each box(sgm&tm).
each bb is measured in 8 places using mitutoyo digital (.00005" read-.00001" off one micron) micrometer.

both sgm .29 and tm sg .30g are impressive when it comes to size vary.you can disregard .003mm off(tm)the manufacturer's tolerance. it's only .0001" and it could be human error.

on staight .36g white bbs, not only bb size vary one bb to another bb, a bb itself is out of round quite a bit. on average, there is .052mm(.002") variation in a single bb. how will it shoot? i have no comment.
either something in between 0.30g and 0.36g would be great, or just real nice 0.36g would be popular as well. Too many people complaint about shitty BBs in the heavier weights, and that match grade BBs only come in less than midweight. Seriously, there'd be a good market outside of Canada for GOOD heavy BBs.
