Question about Neck-Only Resizing

[chuckhammer]

I've been running .30-06 Lapua brass through my Win M70 with neck-sizing only. Some are now at 3 firings. Several of these more "veteran" cases exhibited a pretty stiff bolt lift after the 3rd firing. I guess they're ready to be FL-sized to have the shoulder bumped back.

My question is this:
Is there an accuracy penalty for waiting overly long in between FL-resizing?

None that I've ever noticed....just a PITA dealing with bolt closure. It can suck when your in a hurry.

I went back to FL sizing using a precision mic to bump shoulders .001 back each time....that said it does not seem to matter for me as I just did my best shooting using new brass with no fire forming.

When it becomes a little tough to "lift" or chamber a fired case, I usually bump it .002 to .003. The less the better. I usually do .002 because it will last a couple more firings.

Re: Question about Neck-Only Resizing

I have gone to FL sizing on any field rifle and have pretty much done the same in BR. I have really enjoyed just the Redding bushing type FL and a wilson chamber type seater. I still have body dies and neck sizers but I think it's better to just do it all each time. I have 2 very accomplished shooting friends that each swear on the other routes and have swyayed me at times. But like I said, FL for me as of now. Ha

Re: Question about Neck-Only Resizing

I always run my cases through a RCBS case micrometer* before NO sizing. This separates cases that need a pass through the body die from the cases that can be NO sized.

(*) or any practical means to measure sholder position to 0.001 precision.
