I don't think this is accurate sir from my experience,
If that were the case, you would see all the right handed shooters shooting left handed rifles(because its more efficient right), and that is just not the case
I shot right handed rifles for 2 years in matches and long range shooting because I could not afford the left handed rifle I wanted,
After I finally acquired my left handed rifle, I noticed it is substantially faster for me to shoot a left handed rifle from the left side. At least in field shooting, off a rock, prone, off a log, tires, stairs, barricades, and for sure while you are slung up
On the range, when your all nestled up in sand bags and rests, it might be, because the rifle will not move anyway in between shots because it might be locked in, but not in field shooting.
The hardest thing for me when I had to work the bolt with my right hand, was taking it off of my rear bag, losing my target, cycling the bolt, then putting my right hand back on the rear bag, then finding my target. Then pulling the trigger. Yes, my trigger finger has never moved, but it cant do its job because my gun in not pointed at my intended target.
Or a lefty shooting a left handed right, or righty shooting a right handed rifle, pulls the trigger, uses the same hand to cycle the bolt, while the reticle is still on the target, then pulls the trigger again. much more efficient and way quicker.
All this is from my opinion and experience. Nothing else.
Left handed shooters using a right hand bolt rifle will always be just as quick, if not quicker than their right handed counterparts. Lefty's using a right handed rifle should maintain fire control with the left hand, and manipulate the bolt with the right hand. In doing this the firing hand never leaves the shooting grip, hence quicker follow-ups, given your bolt manipulation technique is squared away. In my opinion left handed shooters should always use a right handed rifle. Makes more sense for efficiency in movement. And the Saving Private Ryan clip is an example of what not to do... Fail...
