First off, congratulations to anyone who can bag the daily limit of 5 squirrels, whether they are foxes or grays (or a mixture of foxes and grays) with a .22 rimfire rifle.

Generally speaking, I tend to agree with DRS that successfully hunting gray squirrels with a .22 rimfire rifle is more difficult than successfully hunting fox squirrels with the same rifle. Grays make for a somewhat smaller target and they tend to be much more actively moving about than fox squirrels. More times than not about the time you have your sights properly aligned the gray squirrel moves!!
