My personal opinion is that while I don't believe my .177 HW77k is INHERENTLY more accurate than my .177 Beeman R9 (basically a HW95 with different trim), I have found that it IS easier for me to shoot accurately. Still....I prefer the convenience of the breakbarrel as opposed to reaching into the HW77 "bear trap while fishing pellets into the loading tap". Even though the "77" is easier to shoot accurately I still use my R9 breakbarrel MUCH more often than the heavier fixed barrel.Originally Posted by waggywinker
Hi again, sorry for all the questions but is there any advantage to a underlever air rifle to a break barrel or is it just a personal preferance, thanks, Waggy,,
One potential disadvantage for the R9 is the fact that changes in the barrel pivot bolt tension will result in point of impact shifts. Also, overly tight pivot bolt tension (or poor lubrication) will cause the barrel shims to wear prematurely and provide an inconsistent lockup which can affect the poi. I do have to mention though that such "tension changes" occur wery slowly and probably won't be noticed as the changes are accomodated with normal sight adjustments. After saying this I do have to mention that the fixed barrel underlever HW77 requires no such pivot tension adjustment so this removes another variable from the mix.
Here are a few (exceptional for me) 50 yard groups that I've shot with various .177 R9s, some of which I've owned, tuned and sold over the years......
All targets shot US hunter class field target style like this.

15 out of 20 CPLs through a 3/4" killzone......

A few groups shot when comparing the accuracy of Beeman FTS pellets with Crosman Premier lights from the 1250 count die lot marked box........

A 10 shot group upstairs in the house with a R9 I called "Franken9" because it was a conglomeration of R9, R10 and home made parts.

Another 50 yard target when comparing different pellets. Notice the CPL group in the upper left corner..

My point of all this is that while my accuracy with a break barrel R9 isn't exactly "PCP class accuracy", I can't shoot any tighter groups with my heavier and more awkward HW77, it's just that the "77" group sizes are a bit more consistent!
