Checking bullet run-out (short video)

7 posts in this topic

I have 10 rounds of once fired WW brass for my 7 WSM from my last trip to the range. I'm still in a load development stage for this cartridge. Besides, I want to check the consistency of the Winchester brass, so I decided to re-load all 10. I did the usual brass prep by running the brass through RCBS full length sizer die, trimmed the brass, turned neck to removed high spot, primed and charged the case with powder. I seated the bullet using Wilson die and my K&M Arbor press. I measured the first two round using my Holland concentricity gauge. The third round were from a batch of virgin brass to be fire-formed. I inserted it just for comparison sake. Most of these virgin brass load measured between .003-.005. The fourth one, although measured around .003, was the worst of the 10. The rest measured between .001 - .002. Sorry for the camera movement, it was hard to hold the camera while turning the round at the same time. Enjoy!http://www.youtube.com/watch?v=W5rVxBEmRSEDSC01577.jpg

The only thing I saw was 2 minutes of looking at a gauge. I would have liked to see what you were doing.

This more like a trial run. I'll do better job on the next one.

Here's how the cartridge is position. You rotate the cartridge one complete revolution and watch the dial movement.DSC01578.jpg

This is much better than the last one with a little narrative.
