I'm not trying to come the old acid here mate, but why have you chosen HMR? What do you plan to shoot with it? Why not .22lr? The point is, at your interview the FEO will ask these and more questions. If you have sensible answers there should be no problem, but if the FEO decides you haven't looked into the matter properly he is likely to refuse your ticket until you learn more.
Like I say, no offence intended, and if you are on the case already go for it.
