The hw100 are great rifles 110 shots in .177, 120 in .22 you would get less shots in the carbine version which has a shorter barrel and cylinder. They have a 2 stage rekord trigger, you get two 14 shot mags and it does not double load avoiding pellet jam in the barrel. I chose the .177 hw100t and I am well impressed, it is a brilliant peace of kit. They are very accurate in the right hands you could drop a rabbit at 50 yards, you only need 3-4 ftp on impact head shots only.
Cheers ramcam thats good. what scope is that on your hw100.
