I was messing arround with Gordans Reloading Tool today while I’m waiting for my ADG brass…..
Had a few interesting findings comparing H1000, RL26 and N565. Near max Pressure with a 180 hybrid and an OAL of 3.010 and 22” barrel:

RL 26 is 96.8% fill and 100% burn
H1000 is 107.9% fill and only 98.3% burn
N565 is 101% fill and 100% burn

All 3 where within 10fps of 2860fps projected

Curious what RL23 and 560 showed
Both are showing complete burn but lower velocities than H1000, RL26 and N656.
Thinking RL23 and N560 mite be paired perfectly for the 168vld and 162eld

RL23: 97% fill 100% burn 2782fps
N560: 98% fill 100% burn 2817fps

That’s nuts cause I found higher velocity in 3 different rifles using N560 over N565. RL 26 is the highest velocity I’ve found

Anyone running a real short 16-18 inch 7 saum, and are pushing the 190 class bullets like the atips?
Curious if you can get them moving fast enough with rl26 to run that heavy of a bullet on such a short barrel.
With rl26 my 300wsm pushed the 180gr at 2950-3000 fps
