I tested the 185 Juggernaut/Varget, 175 TMK/Varget, and 155 SMK Palma/8208 loads, respectively, in a 500 yard club match at Phoenix Rod and Gun Club (PRGC) today.
The Juggs shot VERY well. Conditions were calm for most of the 20 round string, with the wind picking up right at the end (which accounts for the 8 on the last shot). After shooting it, I have a lot of confidence in this load and will be taking it to the 1000 yard line at Ben Avery next week.
The 175 TMK shows potential, but needs more work. The wind began to pick up during this relay. My struggle to find the ten ring can clearly be seen in the first half of the string. By the second half of the string, the wind condition stabilized and I was able to adjust for it, with very good results.
This load sits on a node that is just below max and was developed in 100* weather without issues. Today, though, I was getting ejector marks on nearly every shot. I loaded this ammo with a new can of Varget and strongly suspect that the notorious lot-to-lot variation of Varget is the culprit. At my next opportunity, I will put some of the rounds I had loaded across the chrono to take a look at what is happening. Once I have things sorted out, I will take this load to 1000. For now, though, it is not quite ready for prime time.
I was very happy with the 155/8208 load. The wind continued to pick up in the third relay and gave me a lot of trouble. Still, when I had it doped right, I was easily scoring 10's and X's. This load showed very little vertical, pretty much shooting a lateral waterline that moved across the target with changes in wind velocity. I like this load a lot and am confident enough in it to take it to the 1000 yard line.
