Ragwd,

The majority of precision shooters prefer a V-Block type concentricity measuring tool. One of the more prefered is the Sinclair tool.

As for "straightening" a round that is beyond limits, you will find again, the majority of precision shooters DO NOT as it plays havoc with neck tension. Instead, back track and find the reason for the lack of concentricity, be it brass thickness problems, press problems, die problems, etc. (an interesting study itself).

Vast Improvement...

This tool came along not too soon. I very often shoot 300~500+yds. at Prairie Dogs & Coyotes .

IMHO allot of factors come into play for consistency at long distance. I bought the Hornady L-N-L Cocentricity Tool & eliminated one more: Bullet Run-out.

"In the old days" I used 2x4 w/hole drilled in it to tweak the loaded round and get a concentric result. This confession may cause some "Bench Rest Shooters" to become "Noxious" my apologies. But it seemed to work.:eek:

One of the first commercial comcentricity devices, which is still readily available and quite popular, was the Forster/Bonanza Co-Ax Indicator. Recent entries in the concentricity gauge market include models by Sinclair International, NECO, and RCBS. Some models, such as the NECO Gauge and RCBS Case Master, are capable of not only measuring bullet run-out, but case neck variation, wall thickness and concentricity as well.

Good Shooting!
