Competitive target shooting is where you can hone your skills.
We have leagues here in the CT area for three and four position matches. During the fall and winter it's 22's at 50 ft indoors on Thursday nights.
During warmer weather it's 'big bore' leagues at 200 yds.
This doesn't hurt, but it sure doesn't represent hunting either. I know... I've done what you are doing way past 200 yards for many a year... and was pretty decent at it, but its not offhand hunting practice IMHO.
