Well, you guys, you have been truly generous with your advice for Emma's friend. I'm sure he's not the only one who will benefit. However, there are a few aspects you have failed to cover.
Outdoor shooting, for a start. I have done very little shooting outdoors, as I discovered that while it can be a joy in summer, it is far too cold in winter.
Windy conditions are best avoided; wind is very unpredictable and, consequently, are your scores as a result.
I would urge more shooters not to hurry their preparations at the firing point, and once settled down, to use all their alloted time. Rushing the details will only produce unsatisfactory results.
It is bad manners to leave the firing point in the middle of a detail, as is taking a mobile phone down with you. I have heard of someone answering a mobile in the middle of a detail, why he wasn't diqualified I'll never know!
I know some people like to go night shooting. Usually in the back of Land Rover, in order to collect a meal. I hear all the jolting in rough fields has caused more than one bad back!
