A good start.
For the reload, a speedloader would indeed help. Just asking, did you load 6 + 4, one i chamber + 5 in magazine + 4 realod?
Pratice will help, as common here to manage 11-12 rounds in 25 sek with a bolt rifle and magazine change. In theory, you then got 35 seconds for reloading ;). Keep up the good work!
