Thanks! The nose is a tad long, but it looks like Duramag max length (2.310) would put them right around the lands in my tight chamber (I do 123 Scenars with a 0.03 jump at 2.250 OAL) and the base won't go much deeper than the shoulder/body junction.
FWIW, using the 400 yard drop on the back of their ammo box, their velocity of 2850 and sea level density altitude, I back into a G1 of around 0.295
Let's go Brandon!
