yer my r-10 is amazing would really recommend they are brill also you may want to stay German and go for the hw100
Apparently this gun kills no matter where you hit!!!!
I admit to having no confidence in using 177 after a few runners but it was a fantastic gun. I just get on better with 22 and im pleased for those who get on with 177.
In my experience the smaller calibre means a smaller kill zone. You really have to be bang on, especially difficult if your shots are unsupported. I used 177 for a year but switched back to 22 in January and have had more clean kills already.
