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

[JFrank]

I can’t say bushing testing beyond adequate, made a whole lot of difference at short range but it damn sure did at longe range.

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?

You can buy the ones you want then you will have a set.

If you post your chamber neck diameter and the diameter of the neck with a bullet seated, that will help. Check the neck diameter with a quality .0001 micrometer rather than a dial caliper.

Let me know what you're looking for. I've got a bazillion neck bushings here....many duplicates.

Good shootin' -Al

Al,
I have a Tubb fl bushing die. His bushings are quite different in that they include the shoulder and neck in one bushing. He only has .266 and .268 sizes. I need bushings in .270 and .271. Do u know of anyone/ company who can hone these bushings larger? Or who make bushing for these Tubb sizing dies?

 

[AlNyhus]

Bob, Neil Jones dies are similar...not sure on interchangeability with the Tuff stuff, though.

For lapping just a few thou like you need, a barrel lap would do a nice job...assuming the Tubb stuff isn't carbide.

How much neck tension will not allow the bullet to slide back in the case when loaded?

Thats going to vary depending on whether it's lubed, with what, not lubed, brushed or not.

 

[Bob3700]

Al,
I called Neil Jones ( God love him he is 87 years young) and his Bushings are the same size as the Tubb bushings. His bushings have the shoulder machined into them like the Tubb bushings and his are made out of tool steel. He gets $18 each for bushings,
Thanks for the tip on Jones.

Iv been re-reading some of these posts that have been resurrected, and gotta say much has been learned since it started.
As far as learning how much you jam a bullet with out it moving in the case, Iv been having to do some more of this experimenting. Reason being because iv found tune at 25 thousandths in.
My main conclusion is, this. --- Once I got a round ready and done. I got to chamber it and unload it with out it moving. Thats my only sure way of testing weather or not the round is right. The only downside is that it may have more neck tension than a few others. I know I could get a K&M bullet seat pressure tool. Or the other one,
Who else makes a bullet seating pressure tool?

 

[quest450]

AMP bullet seating press is by far most accurate

Measure the b-o before you chamber it. Then chamber it and remove it. Repeat the measurement. And look at how the rifling marks appear compared to when you set it up the find the T.P.

Reading how the Redding bushings can be out of spec has led me to measure my 265 Redding bushing. It is out .0005 from one side to the other. Is this within the acceptable tolerance. I would think it is, but not sure

I grabbed 3 Redding bushing dies and checked the bushing cavity and a .505 pin gage fit nicely.

Al I don't have any pin gages but what is your take on the .0005 . I measured them with a ball mic.

Touch should be constantly changing depending on erosion to the beginning of rifling and how sharp the edges are.

Men that's been some good reading I've went through bout the same thing when I coated my bullets with HBN got a 6 br with a 272 neck shooting 68gr Hill Billy FB loaded they measure 268 so I went with a .264 bushing first 5 shot a .096 the second 5 shot 1.86 the difference the first was Lapua brass 13 th. the second was Peterson brass 11 th. So I'm going up in powder a couple tents on the Peterson hope that works

 

[RRoe]

This is the target with the Lapua brass it has the 13th neck both loads are the same with the coated bullet's

 

[RRoe]

Here's the other target Peterson brass 11th neck and you can tell the difference liked to have drove me crazy and an then it dawned on me measure the neck sorry keep telling me it was to big to post took me a while to figure it out but you can see the difference with everything the same
