Well I shot both my Gamo 1250 .22cal. and NRA1000 .177cal. Sat. morning to get ready for squirrel season. The 1250 shoots so awesome of groups if I can hold it, it will kill them dead out to 40yds. The 1000 will do the same but I'm still struggling with the ups & downs. I can't find anything wrong. I'm going hunting soon my season opens tomorrow.
