6mm Creed Load Dev

[HUNT JR]

Working on gathering load data before I start development. I’ll be using CCI 450 SRP and Lapua brass with 108 Berger elite hunters. I can find good data for N-555 but am struggling to find good data for that combo with H4350. Anybody out there using that combo that can give me some insight on what they did?

Gun is a 20 inch Seekins PH3 and will have an OG65 when I do load dev.

I would just extrapolate the data from another 108 grain bullet’s load data. Start low and work up

 

[43.6N]

Here’s the Hodgedon 2025 page for heavy 6mm creed loadings.

Specifically for H4350. The max charge for the 115 Berger is at 40.5. That would seem like a great place to start.
The max charge for the 108eld and H4350 is at 41.6. That’s probably where you’ll end up with your Berger bullet too.

So somewhere between 40.5 and 41.6 there probably is a safe accurate load for your bullet. At least that’s how I read it.
Hope this helps your search

I used that exact combo and started at 39.8 h4350. Landed on 41.6 which was just under Hornady max load of 41.7 and shot excellent.


See below from Berger

This is where I ended up with every bullet I have tried in my 6CM - typically towards the 41gr and up range with h4350.

What velocities are you all getting with the 108s and H4350.
The 6CM is high on my list for the next rifle

41-41.5 gr h4350.

I am averaging 2930 in my 18” with suppressor. Haven’t checked without but wouldn’t expect a big drop.

I'm at 41.0 grains of H4350, Peterson LRP brass and 108 ELDms. MV is right at 2900-2915 fps in a 19" tube.

I'm at 45.4 grains of RL-26, Lapua SRP brass and 108's at 3,000-3,015 fps in the same gun. Its damn hard to find, but RL-26 works great with the heavy bullets.

My load is 40.0gr H4350 with all other components the same. I think I tested up to 41.5 before pressure was evident. In my 7.7" Bart, 10 shots is .2-.3"

2940 but I'm using a 26" tube.

Im at 41 gr H4350 at 3040 24 inch barrel CCi 450 alpha Brass.
I used this data to get started
