HOLLiS - lksteve covered the bases better than I did. Guess I'm too literal (nice) with my responses. I tried to give you a complete answer the first time. Try what he suggested - shoot a right handed rifle left handed and manipulate the bolt with your right (non-firing hand). Use sandbags and a support for the butt. You will quickly realize why none of us support your friend's comment/advice/or whatever he was doing. And I didn't even think to comment on getting your face out of the way while you manipulate the bolt. I'm completely in agreement with TR and lksteve - no sniper/shooter I've ever associated with would even consider doing what you ask about. Because of the skill sets and the differences in technique, none of the guys I know would even consider your question seriously - nor would they give credence to the supposed "problem" it is intended to fix.
Next point - your question was about bolt action receivers. All military/police (standard) bolt actions I'm aware of are right handed. You're comment about G-3s and FALs is somewhat correct; their bolts are manipulated by the left hand. They do not (technically) charge from the left (charge is Euro talk for load). They are also not bolt guns. Neither one of them are precision long range guns either. Personally, I'm not overly impressed with G-3s (or most HKs period) and the charging handle on the FAL can be manipulated with the right hand by rotating the rifle to the right and reaching across the top of the receiver - the same way lefties manipulate a right-handed bolt gun.
lksteve - I feel your pain. To add to it, I'm cross-eye dominant. I started shooting competitively in JROTC with right handed rifles. Since I was the only lefty, and all the equipment belonged to the school, I shot with what was available. I tried doing it lefty, but the ergonomics weren't working and I went back to shooting right handed. I keep the pistol left handed despite the eye issue because I'm a klutz with my right hand. As I get older it takes more concentration not to cross eye the sights. In fact, the older I get, the more I like shotguns (Rooster Cogburn).
