My neighbor took his son, Cody to Roulons place this fall, for a graduation present.
He was going the cheap route to shoot a management bull. basically a 320 or smaller of the guides choice to clean up the genetics.
The story was the whole camp took a shine to the Dave and Cody who couldn't afford a nice bull and were doing this once in a liftime bonding thing, Well about day 3 after no luck on the "little guys" the guide tells him this is a managment bull so go ahead.
The kid used a 270wsm with factory loads out of an x-bolt and a 2x10 viper by vortex.
Resting off his pack at 200 yards put 2 bullets in the boiler room about 2" apart. A camera crew at the ranch on a hunt filmed Cody's hunt.
420" somthing!
