I loaded my first batch of .308 rounds tonight to try and find a load that my new rifle likes.
First off I used the Hornady COAL and bullet comparator kits to measure my chamber and I discovered that unless I'm going to be using some 200gn+ projectiles i won't be getting anywhere near the lands.
The COAL to the ogive on the 150gn Sierra gamekings in the chamber was 2.365, and that was with the projectile just seated past the boat tail of the pill and I have a limit of 2.244 due to the magazine (that's just shy of 2.800 base to tip.)
So any way I worked out my lengths and then proceeded to weigh my powder.
I'm using AR2206H, min load is 43gn and max is 45.5gn, I've load 3 of each weight at .5gn intervals.
One thing though, the below pic is 45.5gn and it was slightly compressed when I seated the projectile.
Is that normal?

I'm hoping to get out in the next day or 2 to test them.
This was the 2 best groups I had with the Remington 150gn factory ammo.
