Just re read your post, 20 yards is a very long way for a co2 pistol, I only ever shoot a 20 yd comp with a fully charged pcp cylinder in my lp10

The LP10 is regulated, so as long as it's in the green zone you should get the same power wherever the needle sits. I was knocking stuff down at 20 + yards the other day with mine, with the needle dropping well into the yellow.

My Rohm's love the R10, with very good results, I have a Top and a Sport, both of which the power has been changed and both running about 5ft/lb and out to 20 or even 30 yards they do very well. I also have the trainer, which is CO2, would not bother beyond 10 yards with this....

But the R10 are, for me anyway, I think about the best out there...
