I heard a "story" the other day at the sporting goods store, opposed to everything I have heard as true in the past, and I wanted some input from you'all on it before I point-and-giggle. I was looking at Leupold scopes and made the commented about the VX-L scopes not having a 30mm tube (for light). I was told the the only reason American companies use a 30mm was to give more room for internal adjustment, it doesn't help light transition at all due to the fact that the light beam it so small going through that part of the scope already. I had always heard that the 30mm tube transmits more light than the 1 inch tube. What's the real story here? One more question for you all...I am having a 300RUM made (w/muzzle brake). I already have a Redfield style one-piece base and rings for the action. Is there anything wrong with using this or should I buy something better. I don't mind spending money if there is a real performance difference, but not just to buy a name, style or brand. Thanks in advance for any and all inputs, they are always welcome.
