Thought I'd share this session.
I was tinkering with TAC and I had a little Varget on hand to compare with it. I remember somewhere MarkM suggesting Varget, so I gave it a whirl.
Here is a .223 load with Varget:
Lake City 55 gr projectile (from Wideners)
CCI #41 Primer
Brass: various, including LC
Varget, 27.2 grains ... this is listed by Sierra as a max load. Please work up to this.
Case prep: standard Redding resizing die, trimmed to 1.75 inches (Giraud).
Seating: COAL = 2.25 inches.
Crimp: None.
Range: 100 yards.
Temperature: Approximately 60 degrees F (Kestrel battery died).
Humid? Yes, > 50%.
Velocity: Chrony battery died, but approximately 3,000 fps out of a 20 inch bbl per Sierra book data.
Upper: BCM 16 inch M4 carbine upper
Optic: Aimpoint T-1 w/ LaRue Po Boy 2.5x magnifier.
Position: prone with magazine touching ground.
Here is my reference with M193: (5 shots)
(Don't laugh too hard)
Here is the Varget load - really, for a training round, not bad. Worth additional exploration.
I could use your eyeballs on this - just to double check for pressure signs. No splits on necks or case head separation, so here are the primers:
I'm liking this load a lot - Varget is cheap and readily available, will get me minute of bad guy performance at 100 yards.
