I’ve never shot a deer with a group yet.
Shooting groups with your rifle is great fun, great practice, and educational on the capabilities of your combination of rifle, scope, and ammo. Most of us do it, no drama.
The consequent reporting of the rifles accuracy, brilliant selection of reloading components, and our own ability to shoot, modestly presented of course, delights us in our story telling.
If the reports were true you would wonder why people bothered getting match grade rifles because our hunting rifles are so incredibly accurate.
A lot of the reports are presented without regard to statistical analysis. If you ran a confidence test on the data presented, the test results would fail miserably.
All this fun may result in an over emphasis on group sizes and a lack of practice on the very important skill of putting your bullet cleanly on your intended target.
Accurate alignment of sights and development of basic rifleman's skill will better contribute to achieving the goal of bringing home the quarry.
