What BB weight do you run and why?

.32. I found it's a pretty good mid-point for performance

I've been using a bunch of different weights recently and getting a little fed up of forgetting what weights are in my speed loaders. Thinking of standardising and running .25g Mainly because thats the upper limit on some cqb sites we play at

.30g is the GOAT! lol

0.25g used them since i started and just kept using as they are cheap and do me well enough for the site I'm at

And also I use the same weight on my pistol and gbbr and never had an issue

With a GBB, the minimum recommended BB weight is 0.30. Modern GBBR prefers heavier weights.
