I am in the process of gearing up for deer season and loaded some RL-22 and 140 Bergers VLD. I have a Sako with a custom Brux 26 inch pencil thin barrel and made 6 loads in .5 increments from 66.5 to 69 grains as a work up to find accuracy / velocity with some good case fill for consistency. I started close to max as manuals indicate and up to under max pressure as Quickload indicates. At the range I set up my Oehler 35 and settled down to shoot my first string of 3 rounds, mean speed average was 3275 fps with 14 ES and 7 SD. Group was .267 MOA, 2nd group was at mean velocity of 3302 fps with 67 grains with 15 ES and 7 SD but groups opened up slightly to .4 MOA, 3rd group shot a mean of 3323 fps and no pressure signs on bolt or brass. Groups opened even more to .5 MOA. I know that I never have shot a 7mm Magnum with this kind of speed and I decided to stop right there. I chose to go back to 65.5 grains and work up to 66.7 grains and find that sweet spot. Just being wise not to continue to shoot the rest of those loads and pulled out all the bullets.

Any of those would work just fine for 1/2 MOA of.Whitetail

Think I'd stick with that first one.
