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

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.Last edited by CavityBackBullets; 02-05-2021, 03:43 AM.
