Today I strapped a new style HW mod onto my HW80k and gave it a little short range workout. I have mainly been using the 99's and 95 this year, but the extra heft of the 80 was comfortable and reassuring. I put this up to 19 ft/lb last week and it shoots every bit as nicely as the 95 at 15 and the 99's at 11. I think it's just a case of running each gun at the power it naturally wants to do
This is my only air rifle without a custom stock. I think I'll have to fix that now
