FIERCE CARBON FURY 6.5 PRC best ammo?

[Haydar]

Hi there

Hoping someone out there has some helpful info

I just bought this rifle, shot 220 rounds and cant get a consistent tight group. I am in contact with Fierce and they are willing to have me ship my gun to them or their gunsmith rep in Canada, but hoping to try some more before doing that

I hand load, factory loads did not work for me either

What I have available

Reload 22
H4831
H4831SC
IMR 4198

Hornady 147 and 140g eld

Tried mixing a bunch cant get anything solid And consistent. I also tried playing with OAL


Anyone have and recipes I can try?


Thanks !

Somewhere around 54 gr with the 140 and h4831sc
Put 140 at 2.950 oal if it isn't jammed, which it shouldn't be

If it was me I would try 53.3, 53.6, 53.9, 54.2, 54.5 and 54.8 H5831sc
Shoot 3 shot groups round Robin meaning…
6 different targets, one for each load.
Start at 53.3 and shoot one round at the first target then shoot 53.6 at the second target then 53.9 at the third target and so on until you have one shot of each charge on each target then do it two more times.
When you are done you will see what the best load is.
I usually shoot one every 3-5 minutes depending on how hot it is.
I try to shoot at sunrise so it's cooler and mirage is minimal.

If you get pressure signs on the higher loads don't shoot anymore if those.

You can do the same with the 147 but start 1.0 grains lower.

Once you determine what looks like the best, load 10 of them and shoot those 10 at one target. If it's a good load you will be 1" or less for those 10 rounds.

If that doesn't work either something is loose, extremely fouled or you need to send it back.
