I'm posting this in the general airgun section because the Stormrider magazines are also compatible with the Chaser, the Bandit, and the Seneca Dragonfly.
First of all, an apology on behalf of DIANA Airguns.
We should have read our own owner's handbook and corrected what was, clearly, an ill-designed method.
After trying the loading method in the handbook ONCE, I knew we had inflicted on the users a PIN.
So, apologies.
In any case, we designed a slightly different method that we feel improves on the original one and makes the magazines easier to fill, as you are not fighting the return spring tension for every pellet inserted.
The method is posted here:
And it really is harder to explain than to do.
Give it a try and let me know.
Thanks for reading!
