6.5x284 Norma neck tension

[Mcarso1]

So I am still wanting to tinker with accuracy on my CA ridgeline in above caliber and am somewhat new to reloading. I am currently using Hornady competition full length die set but thinking about upgrading dies so that I can work on neck tension. Where do you start with all the different size bushings offered for neck tension? Is there a standard starting point ? Thanks for help and advice!

Using Lapua brass and Redding S dyes, my last four 6.5x284 barrels produced the best accuracy and ES using a .292" Redding bushing with .264" expander, as supplied with the Redding S Dyes. This produces .0015-.002" of neck tension, neck run-outs <.001", and bullet run outs <.002". Neck wall thickness of Lapua brass is very consistent, running .0145-015".

I ran the same as Grey fox and actually he helped me with my 6.5 284 data gun turned out to be less than 1/2 min out to 1000. 4831sc fed 210m primers 140 vld.

He has helped me a bunch to, great to have a place like this to be able to learn from more experienced guys.

You guys using the Redding full die or neck die?

I generally use a FL dye with the shoulder pushed back .0015-.002" under fireformed brass. I have also neck sized, for the first 2-3 shots fired from new Lapua with comparable results. The brass then needs to be FL sized on subsequent reloads.

Ok so I will order up Redding type s full length resizing die part# 77415, I don't see bushings on midway site? They have to be bought direct from Redding ?

They have them: I prefer the stainless...make sure the necks are lubed along with the case when FL sizing

Thanks for the info, any other tips I need to take into consideration?

Morning fellas. So I ordered the die and bushing last night and should be here next week. Got on YouTube last night and was watching videos on set up etc and started seeing where guys where doing a lot of concentricity measuring and turning necks to remove material as needed . You guys doing that or is that more of a bench rest shooter verses hunter/plinker? It seemed interesting but being a rookie not real sure how much gain it is? Your thoughts?

 

[Greyfox]

While I will measure neck and bullet turnouts, I have had no need to turn Lapua necks. They are consistent enough(within .0005") for precision groups, and low ES out to 1000+ yards on .5-1MOA sized targets.

That's really impressive. How much powder are you using and what velocities are you getting?
