6br

[danny45]

I just F.L.resized a batch of Lapua 6 br once fired cases and now I can easily drop in the bullet without any resistance. What am I missing here?

 

[Jmiverson]

What kind of sizing lube are you using? What dies? Have you checked the expander ball diameter?

 

[Ganderite]

Sounds like you have a body sizing die that does not touch the neck.

This, or a neck sizing die without a bushing, or with a bushing that is way to big.

I am using Redding type s match F.L. die set

 

[Alpheus]

The type S FL dies still need a bushing to size the neck.

never knew that

measure the neck of a loaded cartridge and order a neck bushing 2 or 3 thou less. the titanium nitride coated bushing is worth the extra money. if you're easily dropping a bullet in with no resistance, I think you may want to look into getting some brass with a thicker neck. it will be less stressed when resizing and will last longer as far as accuracy goes.

if that is lapua brass I am willing to bet your going to need a .267 bushing, or you can go .266 since it sounds like you have no way of measuring a loaded round to get an idea of what size your going to need now. I run anything from .265 to .268 on brass that measures .269 loaded, this is brass right out of the blue box, if you neck turned at some point your going to need a different size bushing

 

[danny45]

Most of the resized brass is .270 and most of the loaded Lapua brass is .266 to .268. Would I have this issue with RCBS?

 

[yodave]

not with a set of full length dies, but you have a superior set of dies already, you just need to learn how they work

 

[danny45]

I have set up all my other dies the same way and have never had this issue in the past. Are the Redding dies set up differently?

 

[rl4930]

I think the redding dies are great. Get you're necks consistent and order the proper bushing.

 

[danny45]

I will order the bushing immediately. I want to know is it because it is a 6nr or is it the dies themselves?

 

[rl4930]

All redding neck bushing dies need bushings. That's the beauty of them. You can size the neck the exact amount needed.

yes, you need a bushing in the die body to squeeze the necks back down, no expander ball is required as the necks are only squeezed down to 3 thou under the loaded size so they hold a bullet firmly, please refer to reddings website and or your instructions that came with the die set

 

[danny45]

Will do guys. Thanks for the info. Back to the books

Are digital calipers precise enough to determine neck diameter of a loaded case?

It's more important that you measure consistently than the tool that you use. I have never seen a variance of .002" using a single lot of Lapua brass. My loaded rounds pretty much all measure between .268" and .269".

Most of the resized brass is .270 and most of the loaded Lapua brass is .266 to .268

The fact that your sized brass measures larger than your loaded rounds makes it obvious that you have an issue.
