Speed loader ejects all bbs - help out noob

[Booda]

Bought my first gun - g&g raider 2.0e (long).

Anyhow I loaded up my high cap I got with my gun no problem but mid caps I goto release from speed loader and it spits all bbs out of magazine.

Unsuccessful so far getting extra midcaps (cyma) loaded.

Here is link for speed loader using...recommend using only high caps or different mid caps

Any help would be greatly appreciated

Got it figured out. Tried another mid cap - turns out got 1 defective mid cap as other ones tried loaded no problem.

At least it wasn't me doing something wrong.
