It is best to zero your rifle from a bench or small table for a rest, but you will notice alot more recoil at this time as there is less "give" compared to the stand position. This bothers some people. If it does, you can put extra padding between the buttstock and your shoulder.... firm padding, though! Be careful how close the scope is to your eye. It will bruise or cut you if too close!

I don't know about Olympic bulk ammo. Hopefully some other board member will report in on it. FMJ means full metal jacket; sp means soft point; hp means hollow point. Also, ammo makers may have their own special mix of abbreviations but they should have something saying what they are. Other than tracers, any bullet build should be ok for target work. But I would start with lighter weight bullets (150 -168 grain) while you are getting used to the rifle.

Remember to keep your muzzle pointed safely. And a buddy who points his muzzle at you is not your buddy. Anyone.... but anyone.... can make a mistake and leave a round chambered.
