I know it would be potenially harmful to mount a scope and have the objective resting on the barrel of the rifle.

I have a 50mm Loopy on a 300 WSM and there is very little clearance between the objective and the barrel.  A friend was telling me that the barrel wipe might damage my scope.  I haven't been able to find alot of information on this so I'm searching for some opinions, like i said i'm no expert so any and all information would be welcomed.

Barrel wipe? I do not understand, can you elaborate on your concern? If your scope touches your barrel you are in trouble. If there is clearance you are good. Exactly how much clearance do you have?

Friend made it sound like the barrel, under the pressure of the shot bounces/jumps/raises(not sure how to explain it).  So if the scope was to close to the barrel your scope would be in trouble.  Which I have never heard about before but after spending $400 on a scope I didn't want to risk anything. 

The concern would be that when the barrel jumps/bounces/raises, if it does, that the scope would be damaged or messed up.  Like I stated, I'm not sure if there is such a thing but I would like to be sure.

Right now you could maybe fit a piece of paper between the barrel and objective.  Would post some picks but the rifle is back home (long story), so i'm just trying to get all the information gathered before i go home and shoot it.

What I usually do in a case like that is raise the scoped rifle up to a light and if you can see light between the objective of the scope and the barrel of your rifle you should be okay.  Remember, when you get that close of a tolerance, you may have to shave your scope covers to get them to fit between the objective and the barrel or go up a height size in your rings.

I don't think barrel whip would be an issue;  would be more concerned about flex in the scope under recoil causing a problem if you clearance is only a few thou.  Someone had posted a clip early of the extreme flex of a scope mounted on a 50 cal.  Don't know if your 300 WSM would recoil enough to be a problem, try what gozarian has suggested.

+1, this is good advice, also double check frequently making shure your mounts are rock solid.

Heitmann13, I have a setup where the clearance between scope bell and barrel is maybe 0.010" and this never posed a problem.  As long as you have some clearance, you really should be o.k.

A simple way to check for flex in your scope and whip that may cause contact with your barrel, which occurs with most higher power caliber, escpecially with longer scopes, is to simply mark either the bottom of the scope, or top of the barrel with a removable marker and on the other side tape a piece of white paper tightly.  The trick is to do it without marking up the paper before shooting the rifle.  You can find some very slim line markers in dark blue or black that will fit the space, or saturate a piece of paper and carefully rub it on the spot.  After carefully attaching the piece of paper, fire the rifle and see if there is any contact.  If there is contact, check the area of contact.  Minor contact may not mean anything, but is still concerning.  The more contact there is, the more I would be concerned.

wipe...whip, honestly I'm an idiot.  I do know the difference between the two, simple error.

Thanks for the info.  It's like i said, it's not an issure right now, but when I get the chance I don't want to have to think about it then.
