I would like to propose the following concept for an article in your mag:
Airsoft science - article 1, BB weight, fps and accuracy
Basically, with proper resource, a testing of multiple brands of BB at different fps (300 325 350 375 400 for example) at various range would be great to compare accuracy.
Would had to be indoor (no wind), with the same AEG, using a device to make it not move, etc...
This would lead to a great article IMO. And lead to a serie of other article related to airsoft science...
