Hey MT (little Hijack here),
It might help when you first take it to the range to go with someone from your area familiar with centerfires to work though some of the initial bits. If there is someone at your work, for example, who is familiar with 30 cal centerfires and open sights. I don't know who from the OClub is within going to the range distance of your locale, but if you are ever in the Chicago area I will arrange a shooting day out here. Unfortunately, it tends to be an all day event since the ranges I go to are 1.5 hours away.
Now, this is HARDLY rocket science, but there is a big loud bang and big slap and bad habits can develop early on. Unlike a mouse gun like an AR-15 or a carbine. In fact, it might be a good idea to fire some 22 or low powered "assault weapon" type rounds to get used to the basics.
