7prc Starter Load

Doing load development now for 7prc. Rifle is Savage Ultralite with 22" carbon fiber Proof barrel. Using both Hornady 175 ELDX and Berger 175 elite hunter. Powders are Retumbo, RE22, RE25, RE26, H4831SC, H1000, N568. 100 yds for load testing. Velocities ranged from 2800+ to 3078 - and tracked using the new Garmin Xero c1 chronograph.

Didn't have good luck with group sizes for Retumbo or RE22. Best group size with Hornady 175 ELDX was with RE26, 68.0 gr, 2992 fps. Covered group with a dime.
I think my rifle liked the Berger 175 elite hunter bullet better than the ELDX. Very good results using Berger bullet with powders RE25 - 2892fps, H4831SC - 2867fps, N568 - 2883fps. Highest velocity with this bullet with H1000 - 3063fps.
 
Was using load data from Berger on their bullet for 7prc. 70.6gr of H1000, Hornady brass, Fed GM215M primers. Highest velocity for the 3 loads I put together for this powder was 3078.
I'm still working with my 7PRC. I'm running about 2,900fps in a 26" bbl. Looks like there is still some room on the table. Thanks for the feedback.
 
Hello everyone!
While waiting for the gunsmith to change the barrel on my rifle and put a barrel that comes from Brux, 7mm PRC, barrel 28", I am making preparations and gathering materials to make my own ammunition.
That's why good advice would be precious to me, and in order to get good advice, I'll list everything I have at the moment in the hope that one of you will notice what I'm missing or what it would be wise to have in order to make ammunition successfully.
So, I have dies for 7mm PRC.
Primers: RWS LR Magnum Nr 5333
CCI No 250 and No 200
Sellier & Bellot LR Magnum
Gunpowder: H 1000
Reload Swiss RS 70 and RS 76
Vihtavuori N 560
Bofors RP5/NP (identical to Aliant Reloder 22)
Bullet: Berger 180 gr. VLD Hunting

If you were in my position, which primers and gunpowder would you choose to start with? Also, what weight of gunpowder would you start with and at what weight would you stop to avoid entering a dangerous area.
My goal is to achieve a bullet speed of 2950 fts to a maximum of 3000 fts and at the same time be sure that nothing bad will happen to me, neither to me nor to the people around me.
Now, if anyone has a good idea and advice, I'm looking forward to it.
