All good points fellas and I appreciate each one.. I have a second Leupold VariX-III 2.5X8 that has set atop of my Rem. 700 in 270 Win. for close to 30 yrs and I have taken woodchucks out to 200 yds with it and three Whitetails, the last this past fall a doe walking by at about 70 yds. Double lung shot. Nice setup but the outfitter suggested a step up to .30 cal. for elk so I bought a left hand Rem. 700 CDL in 30-06.
Once I get the 2.5 - 8 scope mounted, I am waiting for the correct bases to arrive at the gun shop, I will test fire it @ 100yds to see how it shoots, then my task will be to equal or better the accuracy and velocity of the factory loads with my hand loads. I have achieved this for the .270 but have not loaded for the 30-06.
My friend with the local gun shop loaned me his Leupold VariX III 4.5 - 14 last fall while I was attempting, unsuccessfully, to develop consistently accurate loads for my 260Remington Encore rifle, and I liked it very much off the bench. I do not believe that the 2.5 - 8 power scope will be a limiting factor in developing an accurate load for the 30-06, but a 14 power may make aiming precisely easier for these 66yr old eyes.
I may opt for the 4.5 - 14, set it up with the same quick detach rings as are going on the 2.5 -8, and use it for load development and as a spare in case the 2.5 - 8 gets damaged. There will be many more rounds fired in load development and at the woodchucks that I hope to see this spring and summer before the planned hunt. Both the .270 Win. and 30-06 are going on the elk hunt if I get the draw for license.
Thanks again for your thoughts. Rol
