Please work up from 10% low on all loads. use .2 grain increments when working up last 1 grain to max. We found ARcomp to hit pressure quickly.
The 105 MKZ has been adjusted to 1500 fps - Its been on the site for a little while now
At 2800 fps from a 22in barrel the 105 opens to 700 yards
Many customer report it is bad medicine for whitetails
8208 max load 30.4
CFE223 max load 33.3
Load data from customer - please work up YMMV

Found sub MOA loads with all powders

Both projectiles have seen sub MOA performance to 1000 yards from customer reports.

We did a lot of work on these projectiles for the Grendel.
We have recently filled a good supply of both projectiles.

I had trouble getting consistent seating...and groups with the 118's. ARC load was 28 grains with Hornady Brass and CC1 450's. One group 1/2" next one 2". I was getting 2500+/- out of my 16" ARP.
