RE: target issue
Also forgot to mention... everyone has bad days at the range, do not give up on the rifle, the 710 will shoot.
Another bad shooting ogre that may be rearing its ugly head is flinching. You shoot a few rounds at 50 and they look alright so you start shooting at 100 and by then the recoil and noise is starting to get to you and you flinch. Things you can do to minimize this:
-Wear hearing protection- earplugs at minimum, a pair of muffs over the top even better. Flinching is caused more by sound than recoil.
-practice dry firing- if you can get used to the unnerving ping of the firing pin dropping, this will help immensely.
-Hvae someone else load your rifle at the range one round at a time and hand it to you to fire. Have the person not put a shell in the chamber at random. If you have a flinch, it will become very apparent when you try firing the rifle on an empty chamber.
