I guess my answer to that is, "To each their own." I use both factory and hand loaded ammo for both target shooting and hunting, whichever is shooting the best at the time. To those who say you can never duplicate factory ammo, mostly who would want to? In most cases, hand loads will outperform factory 90% of the time.
As for the comment about the guy in the heated tower, as some of us age, continuing to climb up and down the hill and valleys and cross the ridge lines becomes more and more difficult. The choice is to either give up hunting or settle into one of those blinds or tower you mention with some disdain. I am currently 77 years old. I have gone deer hunting every year for the past 55 years and have brought home at least one deer per year, in most years as tags would permit, two or more. I donate the meat beyond what I can personally use to local food banks. For the last 8 years I have limited myself to a permanent ground blind. As for limited shooting distances, mine vary between 50 yards and 300+ yards. I limit my shooting at deer to 200 yards although have taken a nice buck at 240 according to my Vortex range finder. My food plot is just a harvested corn field or bean field, crops change from year to year. My blind, which is actually out in the open is a 6' x 6' Redneck and of course it's heated. I may be old but not stupid.
Below you see my hunting stand, the longest shot that I have and a sample target, this one shot with my Tikka T3x 270. Almost all of my shots result in one shot one deer dead in place. By the way, the shot to the left, that many of you like to call fliers is simply exactly where the cross hairs were when the rifle went off, not an issue with ammo or the rifle. It was all my fault. All in all, still a dead deer
