Hi,
I wouldn't be too put off by some of the stories about R10 reliability.
I equally wouldn't be too put off by a polymer action.
I've had more problems with my HW101 than my R10.
Both are as accurate as each other when shot rested, but I get better results with the R10 when shooting off hand. If I could only keep one, it would be the R10.
Cheers,
Mark.
