Hey folks,
I'm new to the Grendel and reloading. I just got my bench set up and was looking at the Speer manual that came with my kit. Thanks goodness I have a friend that has been reloading for many years who gave me 1/2 pound of AR-Comp and a few hundred primers(and lots of advise). The data in the Speer manual for a 120gr golddot has 22.7 min charge and 25.3 max charge. as I was researching on this forum and others I'm finding that 27-28gr for AR-Comp seems to be pretty common. I also noticed that for IMR8203xbr Nosler is calling for 25.0-27.0gr for a 123gr HPBT while Speer calling for 22.9-25.4gr of the same powder for their 120gr GD.
All of that being said... where is a good starting point for AR-Comp powder?
My rifle has a 18" Rainier Arms Match barrel 1:8 rifle length gas--(have about 150 rounds thru it able to get 5/8" groups with 123 black ELD-M red tip)
I have once fired (by my rifle) Hornady brass
I have 250 Nosler 123gr HPBT CC coming next week to load up.
Any info that would help me with a loading plan would be appreciated.
Thank you
