Migrant, just to add a little bit further
I have several load tuning articles on my site and I want to find time to put up more info....
Keep good notes. Look for patterns and make sure you can tell where each bullet landed on target...
...the point is to build brass with consistent neck tension. Like consistent powder charge, it is part of creating the same "bang" with each firing.

Has worked for us very well, especially the concept of repeatable neck tension.
Check out the tools by 21st century if you're needing new things. A little more money, but VERY nice. Available in Canada from extreme shooting in Winnipeg.
GGG
GGG has good taste in equipment...he's understands the value of it. (He's likely got deeper pockets

and for higher volume requirements of precision setups this makes sense

) For myself just putting one foot in the rabbit hole I purchased KM turning equipment from Mystic as a cost effective alternative to see if neck turning had any dividends for the smaller volumes of brass in our case. I've been satisfied with the tooling and would purchase more. If you go this route and don't continue I'll take the KM stuff off your hands.
I believe GGG and I were going through the neck turning thing at the same time. I share the same comments with regards to support. Mystic's been great for product and support, I wouldn't hesitate to purchase.
If you do decide to neck turn I am willing to share what's worked and what's failed in our situations to maybe help you avoid any pitfalls that may be discouraging...again when you are ready.
the LEE collet die used with a redding body die when needed
Works here.
...I know the accustock isn't the same as a custom pillar and glass job, but it should be serviceable.
My son's got the accustock on his stainless unit and that turkey's got better groups than me right now...but that will change.
Lots of good posts here. C-fmbi has got some good points regarding whether the rifle is a good shooter to begin with, but in my case the factory stuff was just all over the place, and that's not the situation now. This may just get you better results and there's cost effective options for tooling to try.
