I get a lot of questions about power and shot string info on my guns, so I thought I would continue posting that information from my various rifles here in the blog. I usually respond with the info in an e-mail, but I think putting the info here makes more sense. That way I can just refer folks to the appropriate blog entry. This time I'll cover my .22 cal, AA 410CRBSL carbine. When I have a chance, I'll follow this with the data from my AA 410ERBSL rifle.
The CRBSL is one of my favorite tree squirrel rifles. It is very accurate with the 16 grain JSB's, it's light enough to carry all day, and the shot count of 20 is more than ample for tree squirrel hunting. Especially considering the daily limit is five.
It's been awhile since I've run her over the chronograph, so I ran a couple of strings to see how she's doing. Here's how a typical 20 shot string looks.

The sequential shot to shot consistency is very good. It's one of the reasons that this gun is so accurate. Below is the target from when I originally sighted her in. I wasn't shooting over my wind flags, so I know she can do even better.
To get her sighted in, I set up my portable shooting stand and put a "prairie chuck" target out at 25 yards. It was a bit breezy but not too bad. The first 5 shots are on the black dot at 3 o'clock. I was shooting the 14.3 grain JSB Express pellets. I made a small scope adjustment and fired five more on the black dot on the left at 9 o'clock. Next I moved the target frame out to 50 yards and fired 10 shots on the head. Not bad, but I felt it could be better, so I switched to the 16 grain JSB Exact Jumbos and fired 10 shots on the center bull. Now we're talking. I made another small scope adjustment and fired 5 more shots on the bull at 12 o'clock. Next I moved the target frame back into 25 yards and fired 5 more at the bottom bull. This gun really likes the 16 grain JSB's.

I also used it one time, to hunt prairie dogs with. It's really a bit light for that application. The ever present wind in the dog towns, makes it very difficult to hold a light gun on target. I've switched to my heavier, and much more powerful, .25 caliber Marauder for serious prairie dog hunting.
