Good stuff, LH.
Not only are you getting get practice with your scope, trigger control, breathing, ballistic programs, etc,
you are doing it for a fraction of the cost of centerfire.
Not to mention the usefulness in being able to regularly plant a .22 LR in some "animal's" ear at
100+ yards, especially if suppressed, is not a skill to be trifled with under expedient circumstances
whether it be for food or another reason. Sometimes discretion is vital.
I'd be interested to know what a rifle like that does with the .32 grain high velocity rounds .
The trades offs between velocity and wind drift with the lighter bullet, and, as you said,
transitioning from super to subsonic could make for some interesting log entries...
