Both loads are using IMR 7828 but do not come from any single loading manual. I used several different sources to get a range of what was possible, started working up from below the max and stopped when I started seeing pressure signs, then backed off around a grain. I think the 140 load was listed at the IMR site but I was seeing pressure signs before I got to the max they listed. It shoots .5" groups on a regular basis. Excellent for most any large game, short of bear, you would want to hunt. A friendshot a large cow elk at 220 yards with it, dropped in its tracks and never moved.

I just checked the IMR site and the load they had 3 years ago when I worked up this load has been changed. I don't recall all the other sources I used back then.
