Burris has more internal adjustment then the Leupold, except possibly for the Leupold Mark 4. I can not remember what the Mark 4 has for sure. I use the Burris Blk Diamond 6X24 for shooting 1,000 yards with a Rem. 700 in 300 Win Mag. I use Burris Signature rings with inserts and the Rem. LR (20 MOA) base. With 190grn bullet I need near 29 MOA scope dope from 100yrd zero to get to 1,000 yards. Burris has more adjustments to go further, (which I am currently working on). Ballistic Plex will give you even further use of the scope. Optics are great. I used to think Leupold was the only way to go. Quality and price of the Burris has changed my mind. I do like turrets on Leupold better, but maybe that is because I have used them for so many years.
