6BR & neck tension

[Dave M.]

I’m now running a .265 bushing on a .268 neck.

I’m running a .265 Redding bushing on one of dashers with a .2685 loaded neck. And the other is using a .266 SAC bushing on a .2695 loaded neck. Both rifles have a .272 no turn neck chamber.

 

[Dave M.]

I don’t anneal brass either.
Here’s some once fired bass i sized probably two weeks ago with a .261 bushing, what I’m suggesting is that of all the 99 other things we stress about spring back would number 98 on the list.

Don’t trust the sizes labeled on the bushings. Get some pin gages and measure them.

Some will not be as labeled.

Short Action Customs (SAC) neck bushings and Bullet Central Micron neck bushings are the best I have ever used. The induce almost no runout and are very true to size.

 

[Dave M.]

Well, I always varify the ID but when they are stamped .261 and size .261, what’s the need for pin gauges ?
I’m not trying to be argumentative, I’m just saying IMO there are bigger knobs to turn when looking for performance.

True true. I was merely saying that unless you truly measure the bushing with pin gages, you could very well have a bushing that measures .2605 and then it is springing back to .261

I can’t speak to the BC micron ones, but the SAC bushings are the best I’ve ever used.

100% TRUE SIR
