Would you take the extra power and pop of the .22 Magnum over the more price-effective .22 LR? Here's one man's opinion.
.22 Magnum vs .22 Long Rifle
.22 Magnum vs .22 Long Rifle
According to a MN DNR officer I know, .22WMR is the most common cartridge used for poaching deer around here.I own matching Ruger 77/22 and 77/22WRM All Weather Boat Tails, both scoped. I hunt with both and we practice with both on the range.
Each one has its own place. The WRM has taken lots of coyotes, raccoons, and even a cougar years ago. The LR has taken lots of squirrels and several opossum* as well as uncounted number of rats and pigeons and rabbits.
If I could only have one gun, it would be the WRM and I would headshoot the food.
The test should have included Yellow Jackets and Vipers in the .22LR ammo. The results would have been closer. The ammo shortage being what it is may have made that impossible however. If one wanted to get exotic, the now no longer manufactured .22LR Devastators would have really moved the bubble at closer ranges in terms of "stopping power" but would have eliminated the meat.
* If I had the WRM readily available it would have been a much better choice. It took four rounds of .22LR on both of them to get the job done.
