We got to the knoll with a minimum of complaints and just as our script predicted, deer started trotting by our lookout, looking over their shoulders at the hunters who bumped them. Most were does and fawns, but soon a young buck, maybe 22 inches wide but willowy, came over a rise. I whispered to Merlin that a bigger buck might be next, and I worked the bolt of the rifle to slide a shell into the chamber. The bolt face picked up the shell, but wouldn’t finish the job by pushing it into the chamber. I opened the bolt to see if some obstruction was halting the advance, but the chamber was clear. Finally, I inspected a shell. It was heavy, with a telltale belt at its head. A 7mm Rem. Mag.
