I have the opportunity to purchase a Leupold VX-3LR. However I can not decided which model to buy. I have narrowed it down to the 4.5-14 and the 6.5-20. I will be buying the fine duplex model and I have the mark 4 rings and bases to mount it in. I am shooting a .300 wsm and have been handloading for about 5 years. It will be used primarly as a hunting optic but I do shoot from a benchrest at gongs out to a thousand yards as well. Price isn't an issue because of my supplier, it is only a $50. difference between the two. Please give me suggestions and your experience. Thank you.
