If your linking procedure is non-standard, ensure everyone in the foursome knows what the correct procedure is before dismounting and attempting it on the field. If you must rotate the cylinder manually, something s wrong with the mechanism. Know if the revolver cylinder rotates properly before making a pass at the heads. Landing on it is uncomfortable, the cantle makes a decent fulcrum, and the gun can lever you right out of the saddle. All in all, an immediately self-critiquing maneuver.
New horses can make even the most seasoned trooper feel and look like a tenderfoot.
It's much harder critiquing the performance of others when you're having trouble keeping your own act together. Leaving wet canvas water buckets in the dim recesses of your trailer causes mildew and rot, resulting in holes. Hang them to air and dry out at first opportunity. Water, rest your horse, and check his feet regularly. Without him, you re infantry.
