Been there. Jim G

Yes!! Much easier. Jim G

While I agree with your statement that .0005" increments allow finer control than ,001" increments, I'm not so sure about the button being inferior to a mandrel for the reason you gave. The Redding button I bought is sized to ensure that the ID of the neck is both (a) concentric with the case...

I have only fired a couple hundred rounds through the rifle since brand new a few weeks ago (258 rounds as of right this moment). I have not ever yet fired more than 50 rounds in one range session. F-Class will ultimately require me to fire 70 rounds before cleaning I believe. I use Wipe-Out to...

That was a completely unwarranted cowardly attempt at a put-down. I've compete plenty in local matches that I was qualified to compete in, and enjoyed the process. But it would be stupid to try to enter an F-Class or PRS match right now because: - I have fired only a grand total of jst over 200...

I do understand. I just like to do TWO htings at once: (1) Find the nodes and (2) get some early indication of group size at that node by firing more than the minimum number of shots. Jim G

That may be true, BUT, the rifles shoots really small groups. I am at a point where the rifle and ammo outshoot ME, so no point, at least yet, in trying to uncover even more accurate loads, since my shooting is not good enough to produce smaller groups if the rifle and ammo can. I need the...

No. First, I tested 10 different powder loads, 0.3 grains apart, 5 shots each, to find those 2 node loads. Then, I loaded 25 each of only those 2 node loads. Jim G

I did. I tried every 0.3g for a total of 8 different powder levels initially. There were 2 clear nodes. Then I tested the 2 nodes against each other. No point in going finer to 0.1g differences around this lower node, at least yet, as the combination of rifle and ammunition currently is more...

There were 2 nodes in the ladder testing. The other one was at a higher velocity, but it was not as accurate when I tested using 25 rounds of each. Jim G

Yes, you are right about the terminology: Redding calls the part that sizes the INside of the neck a "size button", not a mandrel. I'm using a nitride one,a nd it seems to be doing a great job for me on the Lapua cases, in conjunction with the neck sizing bushing. Jim G

Yes, I know that at some regular intervals, I will need to full length size, but as long as the cartridge is properly chamberable, I will neck size only, as that will minimize working of the case AND improve accuracy. My load is VERY moderate (2700 fps for 120g bullet) and I do have the 3-die...

Yeah, I did. :) Jim G

Yes, I guess there is some witchcraft, because I use the Redding .291" sizing bushing, and as the math I showed a few posts earlier shows (.291" minus (.0145"x2 wall thickness) - .2636" Hornady bullet OD), it makes for a "perfect" .0016" neck tension. And that .0016" neck tension is sufficient...

Depends on WHAT you are measuring. For most items being measured, you use the wide part, which on the best calipers, is also a special harder material than the rest of the jaw. But for items that are both curved and concave, you must use the thinner part of the jaws in order to avoid "bridging"...
