Ya Harv, LOVE those R-11's!
I spent last Summer learning how to "drive" the pellet hole around the paper at 20-50 yards. It's almost Scientific how you move it back and forth! Mine prefers the 4.53 AofA Field Target Pellet. Using either the Target Knobs or the Magnification or in a very minor movement,the Focus I can vary the POI of the pellet all over the paper.
Now this proves that you MUST sight-in centered and focused at your desired range to get pinpoint accuracy, but it also shows just how repetive the HW Powerplant of the R-11 is once you get her broken-in... Variatable Scopes are almost a curse because one wants to use all the settings but for the sake of accuracy at the ranges we shoot you can't. I know they're NOT supposed to move but they do...
I haven't Chronied my R-11 but feel that it's near the advertized 900 fps mark with the AofA (JSB) by the pellet drop. This would make it a formidable Hunter (Kinda heavyto pack all day). I usually shoot off the bench but I've considered having the BBL Weight removed by Beeman's (It requires Heat to break the Epoxy loose) to lighten the gun up for offhand use. Probablly won't tho, cause the Bluing on the Sleeve is so BEAUTIFULL!
Have fun Harv!
