So, I just started load development for my 25 Creedmoor. Barrel already has 200 rounds through it. Found a decent load with 121 Hammers to get me through this passed hunting season. I then bought some 115 Tipped Hammers to try out. I loaded a 10 shot ladder from 36gr - 40.5gr of H4350. Here is the 10 shot group.

I figured if 10 shots grouped like that over 4.5 grains, I could pick any charge weight and it would probably group pretty good. So I picked 40.2gr to get the most velo without hitting pressure. As 40.5 is pretty close. Here were the results a couple of days later.

Then I loaded 5 more and shot this group a few days later.

That round shot 2966fps and it still grouped with the others. I never messed with seating depth. I stayed at 20 off the lands. Im just just 20 total rounds in for this load. Since this rifle is for hunting, I was happy with the results and stopped there. This was at 100yds as I don't have access to shoot further. Sorry for the long post, just wanted to share my experience.
