Hi all , new to the forum ,l have had a hw110 .177 for a while now and I love it ,but have just acquired a hw100kt adjustable laminate in .20 so am really looking forward to see how it performs in the field ! I purchased it as a bundle with a lot of kit that I have already have so will be selling some on soon. I've always considered a.20 over the years and this came up so I grabbed it ,eight months old and unused as is all the kit with it .Who else has this controversial calibre and what do they think of it ? I have zeroed it in the garden at twenty yrds and it's spot on with H&M ftt at 680fps .I had a bit of a moment when after the third shot the pressure dropped and even more so with the next and the a pellet being stuck in the barrel because of lack of pressure ,but after looking on a few forums found it was just the cylinder needed tightening and all is now as it should be ,am hoping all will be good from now on .
