Not long ago I bought 100 168 Gr match bullets to try. I got far enough along to get to the velocity threshold I was looking for when all the bullets etc disappeared. I only had enough to shoot my first F Class Match with, much less tweak a good load, and I also shot poorly.
Since then a kind member has sold me 300 168 Gr SMKs and I have tested not only the load I shot that day, but a couple more as well. The load I shot that day (Load #7) did not fair well in testing, but Load #8 did. I tweaked Load #8, and Load # 9 shot pretty well at 100 yards. Getting closer. The two low shots are my fault. I think the bottom one was bipod related as I am getting used to shooting with one. The horizontal spread is me ignoring wind changes wanting to see how affected the shots, and also not wanting to wonder afterwards if it was me holding off, or the load.
I changed to a .338 bushing and dropped .2 Grs powder. (RL-15) Oh yea, and changed powder lot #. (New 5Lb Jug) I'll shoot those 15 soon. Yea, I know, I changed three things. *sigh*
Anyway, I have been trying a couple of different things as far as sizing and seating and checking run out as I go.
The setup in the pic is giving me .00025 to .001 run out. Either seater, it doesn't matter. I am using the LNL with the Redding bushing type full length sizer and an arbor press with the Wilson hand die. I also have a Forster bushing bump die, and it does just as well as the Redding FL bushing sizer.
I am sizing first, making sure the shell plate is lined up right and when the case first starts to make contact with the die, backing off the handle a hair and then running the case in the die, just like I would with a single stage. I am doing the same later when dropping powder and seating the bullet. I am not weighing charges yet, and may not, at least not for 300 yards.
I am pretty happy with .00025 to .001 max run out. This is with once fired Lapua brass. caught it on sale at Midway.
