Soft jam and neck tension, how do they relate, and how much neck tension before your starting to go further in

[jimmymac]

I've been using the split neck for 25 years. It works better than anything I've ever tried including the "Wheeler method" . It's not monkey motion.

Maybe give this a go and it may change your mind. I've tried them all and this is as fast and accurate as it gets. I shoot a half dozen different bullets and this simple device is the cats meow. I can run through them all in a few minutes and record the measurements for reference. Math doesn't lie.

The split neck method would be third on my list as compared to the @gunsandgunsmithing tool and the Wheeler method.

If you have access to pin gages, it's well worth the time to 'qualify' the bushings...make sure the marked dimension is what they really are. -Al

Iv often wondered about the accuracy of the bushing's Iv used. That's a good point. I have two bushings that are marked .266 I use quite often and I swear one's tighter than the other.
These pin bushings,? I'll look into these things.
Thanks!!!!

There are some very knowledgeable fellas chiming in on this thread, It’s also gone from what’s it take to hold a bullet while jamming to something else. My question to @Bra/shooter is what are you shooting and what distance are you shooting?

In door match trying to up my x count. Shooting a 6bra 12 twist urban rifleman bbl against a bunch of ppc shooters. This bbl I got now is by far the best one Iv had thus far. I think it's just broke in now. Iv gotten a great bunch of advice here, (you are correct) And I acknowledge that the information Iv gained here is (being a member of the forum) has saved me tremendous time and hard ack learning to shoot bench. I'm by no means good , I just like to shoot targets for the sheer fun of it, and go to a match once a month. It's pure addiction.
But, yeah . I thank y'all for all the advice.
My initial post, I was wondering about what neck tension would start jamming 68 grainers in the lands. I thought ther may had been a general consensus on what neck tension starts to jam and not let the bullet slide in the case. Iv got limited number of bushings and I think my set up I would benefit from doing a genuine neck tension test. I got my powder charge down, I got my brass prep down, my bullet sorting up to speed, and my seating dept pretty much right at Jam. Since I haven't got into neck turning, I may be limited a little, so the only thing I could think of to do next is get a grasp of how much neck tension I'm running, understand it a little better and apply what Iv learned. Just trying to take one variable I may have a little bit of control of and make it work in my favor.
So, I'm gonna find a few more bushings, that are marked real good. Try maybe get something that could verify their measurement, and clean some brass in my load bench!!!!

Edit: 100'yard indoor. And (300 meter score and group)

Another question; To get ahold of how your seating bullets precisely, Iv been using a Wilson inline seater. With a arbor press. What are these gauges I see on some people's loading presses? Are these gauges to see how much down force is applied to seat the bullet to the desired depth?
Please excuse the ignorance,

You guessed it right.

Jim, Mike's tool really is slick isn't it? Like all of Mike's stuff, it's well thought out, well made and just simply works. There's multiple barrels rollin' around on the work bench right now for a couple upcoming projects. They'll all get checked with any of the bullets likely to be used.

Just recently, the seater stem in one of my Wilson 30BR dies needed to be replaced. Mike's gizmo made the process of verifying the 'T.P.' stupid simple. Back to backing those figures with the stripped-bolt (aka Wheeler Method) resulted in identical stem lengths for the 'T.P.'

I modify quite a few fired cases for use with the Hornady checking tool. One need only use that tool (or the split neck method) and compare results to the other two methods to comebto a conclusion. Seating depth is the #1 thing that people don't get right.... connecting those dots is pretty easy.

Good shootin' buddy. -Al

Mike’s tool is really good and intuitive. I’ve also regularly been within .001 of the Wheeler method using this tool.

The spring tension on the indicator is very light and provides precise measurements. The instant the bullet contacts the lands and bottoms out the plunger there is your reference number to do the math. It’s also easy to share and is quite repeatable. Very well thought out. It also makes it super easy to set up my Wilson Sinclair micrometer seaters without having to guess. This tool plays nice with my seaters.

Thanks for the clarification, I’m not a short range shooter, i shoot long range.
Some of the best SR guys in the country are on this thread, I would listen very carefully to their advices.

I trust the LE Wilson bushings but I've never trusted the Redding.

@jimmymac is a prime example. Jim established a new UBR record this season...on Father's Day weekend, no less!

Regardless of brand, we can trust or we can verify and know. One way sorta' works. The other absolutely does.

Oh I agree. I have definitely had mismarked bushings

I've heard this from multiple people.

Also have had excellent accuracy with all Wilson products.

And while you're at it, check them for concentricity too (if you have the capability). I have a box with 5 or 6 of them that the hole isn't straight in the bushing.

As long as I can get Wilson bushings I will not buy the Redding. Had several that were not the correct size as labeled.

Does Wilson make a bushing set?
A set you can buy that has 5 or six or more in them, or do you need to buy them individually?

Bruno’s always had the best prices on Wilson dies and bushings.

I have trued up bushings in the lathe. Most are out of round and not square. Cant say I shot better though.

I'm glad you mentioned that about "out of round"
Iv starred, and starred at two of these .266 bushing's Iv been using the last two years just thinking they look messed up. I mean they do the job, but I can turn one , one way, one the other and see the out of round with my eyes.
I'm not the only one then.

Interesting. I have a SAC bushing that induces more runout than it’s Wilson counterpart of the same size yet I’ve had better results on target with the SAC.
