Mike,
I am booked out to Aug right now, and a rifle I get in Aug may not be ready until the end of Sep. That said, I'll help you anyway I can.
Here is the link to the load development request: https://www.unknownmunitions.com/services/load-development/
I too am a competition BR shooter. I shoot 1000 yd BR. There is simply no shortcut to thorough tuning. If I do not make the extra effort and obsess over things like repeatability and ES when doing my initial tuning at short range (200 or 300 yds), then I won't be able to successfully tweak...
I am not showing good, bad, and ugly; I am showing a normal load development process that has resulted in good loads. Every barrel out there will shoot bigger and smaller based on powder charge, seating depth, type of powder, type of bullet, type of brass, type of primer, and so on.
We are...
Sorry for the late reply. I just saw this. I thought I was watching this thread.
The production load achieved 2875 FPS out of a 26" barrel using ADG brass, 42 grains of H4350, and the Hornady 143 ELD-X.
With Peterson brass in a 24" barrel, I got a load to tune with 140 Beger Elite Hunters...
When the magazine limits the length of the cartridge, then COAL is what determines the max seating depth. I then find a BTO that allows for variations in bullet tip lengths so that the longest bullet still has clearance in the magazine. The data I provide the ammo loaders shows both COAL and...
The powders and seating depths are listed on the targets. If you can't make it out: N570 for the 300 Norma, H4350 for the 22 Creed, IMR 8208 for the Valkyrie. I have some more loads to post after I finish putting the customer's folder together.
In this thread I will post the good loads I have found when developing customer's rifles. The usual disclaimer. These loads were safe in the rifles I worked them up in. If you try one of these loads in your rifle, start low and work up, stopping and backing down at the first sign of...
EDIT: I have my process pretty well ironed out and I am ready for more rifles.

I have just started this position and am still getting organized. I can't take in any more rifles right now. I hate having to tell people that.
I...
