Ive not spent money on scales for that reason--i just use cheap beam & elec scales & double weigh each charge while continually zeroing the scales through a session.
I too constantly get stupid differences in velocities & dont know why...i have no doubt my scales dont help here, but i get the impression neck tension is my biggest enemy..
What is the video Tas...?--the same one you put in the brass thread i posted or a different one...?...(just finished watching that...thanks)...

I am learning every day and still manage to stuff things up, so I am not any sort of guru. To become proficient at every stage you should first try to limit your input into the process. If you are worried that you are bumping the shoulder inconsistently, try not bumping the shoulder at all. If it is hard to apply a large amount of neck tension consistently then try a die where you can adjust the tension. It is easier to apply low amounts of tension than large amounts consistently.
I do not like expander balls in sizing dies, they often increase neck runout.
For Stix, try reloading your Nosler brass without sizing at all. Once fired brass will have enough residual neck tension from spring back, to hold the pill. See if you get better groups from no sizing. If you do the resizing process is costing you accuracy.
SCJ429 wrote:After you have fired the new brass, it will come out of your chamber nice and straight. It should still have enough neck tension, just pop the primer out without sizing the case and reload. This will only work for one or two reloads and the brass will work harden and not have enough spring back to hold the pill.

I fail to see how this will help me...?
Im not being smart...rather, i guess im asking...
Here's how i see it...
To my mind, the very first firing will for sure have different neck tension between cases due to out of round necks...
The subsequent firing will possibly have a more consistant neck tension,, but there after (the following load) it will change again (from having to be sized)...so i wont get any conceivable consistancy until the third firing & after...
Again, im not being diffucult, im just not sure what, & want to know what you're suggesting this will acheive...

Your brass came out of your chamber perfectly straight, no sizing ensure it is still straight when you put the loaded round back in.
The no sizing of the neck ensures very light neck tension, if the tension is different between cases it will only be slightly so. These things gives you the best chance of shooting a decent group. Only the variation of the brass will add to your Standard Deviation.

What size scope are you using on your 204? What bullet are you using? What groups is it producing?

You should get some pretty good results out of 8208, speed should be similar to 2206.
What make is this rifle?
