It’s like anything else, if a fella buys a rifle puts cheap glass on it the grabs a box of Remington corelocks and expects to go out and be successful he’s fooling himself. These are also the folks that boresite the rifle and only shoot it maybe once a year and at an animal resulting in a wounded/lost animal or a miss then blame the rifle. Truth is to be proficient with any rifle, regardless of caliber, it takes acceptable quality accessories, good ammo, and a ton of sweat equity via practice.
Another issue is using calibers with either poor bullet pairing for game sought or just flat out pushing the caliber beyond its intended threshold.
Unfortunately the above examples are waaaay to common. The average North American hunter is unfortunately part of a group of people that, as a whole, love everything about guns except shooting them. Additionally, the average hunter thinks he knows a whole lot more than he really does.
Don’t get me wrong, there are some super squared away men and women out there and a hellava lot of them on this great site which makes hunting with them a true joy. But..... wow have I seen some fellas that really need to be honest with themself and put forth the effort.
