So I've just recently got into reloading for my 7mm-08 Winchester Model 70 and being a total perfectionist, I'm always looking for ways to improve. My latest question concerns neck turning.
I did some looking here on this subject and managed to find a thread from 2011 where deadshot2 said he neck turned all his once fired brass to get consistent neck thickness by simply taking off the high spots. He said he had great results keeping his groups consistently under 0.25" at 100 yards with similar results out to 300 yards from his factory gun.
This is definitely what I'm aiming for, so I'm pretty interested in giving neck turning a go. But I'm not sure what variation he was seeing in his unturned brass to begin with that drove him to start turning his necks.
To minimize case prep, I decided to purchase brand new Lapua brass since it seems to be the overwhelming favorite for quality and consistency. However, I have noticed a variation in neck thickness of up to 0.0015" on a fairly significant number of cases in the lot I purchased.
One of the things I read is that consistency in neck thickness is crucial for making sure the bullet leaves the case mouth evenly as it starts it's short journey to the rifling. That way, it enters the bore perfectly straight and even.
Many of the top shooters out there will say you should have less than a 0.001" variation in neck thickness and some even say less than 0.0005". Clearly, my new Lapua brass is exceeding these tolerances. But most of these folks are shooting custom precision rifles out to 1000 yards and require those very tight tolerances.
It's pretty clear deadshot2 decided it's worth it to neck turn his once fired brass, but I'm not sure what variation in neck thickness he's getting after neck turning. Perhaps I'm already within acceptable tolerance with a variance of 0.0015" in my Lapua brass for my factory rifle in the 100 to 300 yard range.
I'm curious what others think about this. Hopefully, deadshot2 will see this thread and chime in as well.
Thanks in advance for the feedback everyone.
