As a side note. I ordered the same stock as my first build to include color and model. Ordered directly from HS Precision. Check out the difference in color. Both ordered as Gray with Black Webbing.

It's been great to see your project come about. I like your stock and scope choices. I'm currently waiting for my 338LM so this has given me some needed distraction. You have an awesome rifle and scope. I'm interested to see how your load development goes. The best to you.

Thank You! Load development will be starting soon as time permits! I'll continue to post my progress.

Such a cool build. Awesome how you have taken the time to post up every last detail, links to the components, as well as your experience with CPG.

very interested to see how it shoots!

I got the opportunity to shot this rifle for the first time tonight. Although I only shot three rounds, Freaking Awesome!

For my Break-In and load development, I will be shooting:
300 Grain Berger Elite Hunters
H1000
215M Primers
Lapua Brass
@150 Yards

I received the rifle with 10 rounds fired, shoot clean, shoot clean method. Everyone has their own method of barrel break in and this is mine. I will be shooting 3 rounds a night followed by a cleaning. I'll do this for 15 rounds (5 sets of 3). Then do 6 rounds (1 Fouler + 5 Shot Group) strings working up in powder chargers!

Started at 88 grains @ Magazine Length (3.825).
