IMR 4320 - Varget replacement?

[<MADDOG>]

I just thought I would share some informal load testing with you gentlemen...

As we all know Varget has been a PITA to get ahold of. A month or two ago, IMR 4320 was available in 1-8LB quantities, and based on my google-fu, I ordered 8LBS based on some opinions of others that it was very similar to Varget. Below are my initial testing results: bash as you may...

Below is a pic of my latest testing today @ 100 yds during the beloved wind and at 65':

Left side: a ladder test of 77 SMK's. 7 shots total. 21.9gr to 23.1 at .2gr increments. No signs of over-pressure of any load. I did pulled the far right round.
Rifle: Savage 12FV(?) with 16x Millet

Right top: two different zero groups with 77 SMK's at 23.0 (I already tested that load over the past month)
Right bottom: British Radway SS109 tested for reference.
Rifle: Maddog AR15 built with 18" DTI barrel and ACOG TA11.

I did not chrono any loads due to my dumbarse failing to bring a good battery, but those will follow. As a note with the Savage; I was targeting a round I put in the paper with my Varget load (24gr @2950 FPS) with a 3 MOA adjustment down (you can't see it from from my shitty photography), and it was spot on. Which leads me to believe the velocities are close...

I also have promising results with .308 with 175 SMK's with my "Maddog built" LR308 during my initial ladder testing, but I did not take pics. Those results will also follow...

Long story short: if you guys like Varget, you may wish to give IMR4320 a try!
