It happens!
Example: I paid $1,500 for two first generation Kimber Montana rifles, 280ai and 7mm WSM. The seller wanted a 7 PRC that he could hang a "can" on and shoot an elk at extended distance. I ran into this gentleman a few weeks ago and asked him how his plan worked out. He said that he missed a "bull of a lifetime" at extended distance with his new 7 PRC. Seems that he took a fall hiking in and bent the "CAN"! Ended up shooting the end of the can off with the first shot!
Example II: I paid $1,000 for a Christensen Ridgeline, 6.5 PRC 24". The gentleman wanted the FFT 20" barrel to shoot with a "can". Four months later I bought the FFT from him as he felt that he needed a chassis rifle that was a bit heavier.
Example III: I paid $800 for a Remington KS Custom Mountain Rifle, 280 Rem. The seller wanted something that he could run a "can" on....
No doubt, the new "long range short barrelled can trend" has made additional rifles available.... and that's "OK" with me!
