Neck turning question - Question on Lapua brass

[Varmint Hunter]

Am I going down a rabbit hole here with no returns? I'm not using this ammo in competition but rather in production made rifles for hunting. I do like to have very accurate ammo and will do what I can to make it as accurate as possible. I wasn't considering neck turning because of tight chambers in competition rifles. I was only seeking concentric brass and an equal amount of grab on the bullet all the way around. Was also hoping to reduce run out. I was thinking that the concentric brass would be more true coming out of the sizing dies. Especially if you were using bushing dies.

I wouldn't even consider turning brass for a production rifle. The chamber neck could already be very generous in diameter. Turning your case necks down would only increase the clearance which might not be helpful.

If you decide to turn some necks, only turn down 1/2 of them. This way you can try the same loads in turned and un-turned cases. Report back here with your findings.

It has also been discovered that brass with uneven neck wall thicknesses usually have uneven shoulder or body wall thicknesses, or so I have read. If that's the case, there isn't anything that can be done about those variances.

The easy button is to just buy quality brass. (but testing with a few cases won't hurt)

Good luck either way.

"I wouldn't even consider turning brass for a production rifle. The chamber neck could already be very generous in diameter. Turning your case necks down would only increase the clearance which might not be helpful." Good point.

"If you decide to turn some necks, only turn down 1/2 of them. This way you can try the same loads in turned and un-turned cases. Report back here with your findings." Experiment for myself and find out what happens. Good idea.

" It has also been discovered that brass with uneven neck wall thicknesses usually have uneven shoulder or body wall thicknesses, or so I have read. If that's the case, there isn't anything that can be done about those variances." I've read that too. That's why I have one of these devices and use it.

This all sounds like good advice from someone who knows a thing or two. Thanks.
