I went out today and shot my 20 SF with standard factory barrel. *I was using underwood 200gr XTP's. I was getting 2" groups at 7-10 yds. off-hand. *When I went out to 25 yds and shot freehand and with a make shift rest, my groups went out to 12-18". I didn't feel as though my grip was off. I'm using advantage tactical sights. *I also have Talon grips on it. *I really want to use this for hunting but am not very happy with the groups. People are shooting out to 50-100 yds and killing deer. I would like to be able to do that too.* So, my question is, what if anything should I change? *Barrel? Ammo? Extended barrel? As always, thanks in advance!
