Considering purchasing the above as I’ve never owned one but any particular characteristics of the two calibres (.177 & .22) I should be aware of ?
It will be used for bench rested indoor shooting out to a maximum distance of 40 metres, predominantly indoor with a possibility of outdoor HFT and that’s all, no hunting.
On the face of it, .177 appears to be the natural choice but there maybe other factors to consider ?

Thanks.
