I never stop learning----This weeks lesson herein

Thanks for sharing, Ive had my finger on the trigger to order a gauge for a while but just can't seem to pull it.

Well, I believe that the bullet is being forced back toward the center a bit. But I appreciate your opinion.

I'm also thinking that large amounts of runout could be the equivalent of a chamber ream not being concentric woth the bore, which I do believe woukd be near the top of.the list of potential accuracy problems. I'm no expert, just talking here. The results on target will ultimately determine how much I care and how much effort I will put toward fixing any runout issues.

When I got my concentricity gauge I measured some .300 win mag loads that I just finished. The worst one was .002" runout while most were less. I thought that I wasted money on the gauge or it did not work. For the next hour or more I was digging out boxes of reloads and some old factory loads from 20 years ago. The gauge worked just fine. I found that rotating the shell three times while seating the bullet helped. I also found one set of .308 dies just needed to be replaced.

Which gauge did you get and are you happy with it?

 

[Bang4theBuck]

The gauge I got is a Redding. I like it....its simple. The hornady model is set up to 'adjust concentricity' as much as it is to measure it. I woukd not personally want one of those. Just my two cents.

I got the RCBS. If I were to buy it again, I would probably get the Sinclair. That's just due to it having rollers bearings instead of a V slot to roll the round in.

I'm definitely "NOT" going down that "rabbit hole"……I have too many mental issues!

I have a method…..approved by the SWAG system of hand loading. I go through the usual loading steps, minus a few that you guys use, however when seating the bullet……I fully seat, rotate the loaded/seated cartridge 180 degrees, then seat again.

I can't attest to this as helping minimize runout or just screw things up twice! But, I get groups about as good as possible considering……the shooter, the cartridge, the load, the rifle/scope combination, and felt recoil which may fall into the shooter category. I constantly get one hole @ .375"…..until I fire the second shot! memtb

Thanks for that, it made me belly laugh.....we need to remember what the weakest link in the chain usually is, don't we!

I 100% applaud your effort to find out for yourself!! ......If more folks took that approach there would be less useless old wives tales floating around.

I have the Hornady concentricity gauge and have straightened many bullets with it.
I really like memtb's idea of turning the seated bullet 180 and seat again,sounds like it work well!

As I am seating the bullet I rotate it three times. I don't really know if it helps, but it doesn't hurt.
