What Bushing sizes for Redding Dies 308 Lapua Cases

I need some help with selecting sizing dies bushes for my 308 dies.

I have ordered Redding Competition Dies but need to order some bushings for it.

I will be using Lapua brass in 308 Winchester

My issue is that I can’t resize until i get my bushings and I can't work out what size bushings until I have reloaded a cartridge to measure it.

Could some one suggest a starting size bush for the 308 Winchester with Lapua brass. I won’t be turning the necks.

Hi,

For Lapua brass purchase two bushings.

Size 0.336" for new brass, and as the brass gets used and the necks thin down use a 0.335" or 0.334"

Get the ti-nite coated ones as you don't need to lube the necks. They are more expensive than the plain hardened steel but less of a hassle.

Thanks Barry,

I have ordered the .336 and .335 nitride bushes

I just went with .334 TiN, and all seems to be good. Gives consistent neck tension, as each projectile when seated, goes in smoothly!

PS: Anyone looking for some well used Hornady reloading dies :-)

I finally replaced mine with a Redding set after 20 years! And I'm not going back!!!

I have a selection of ten different sized Redding Tin bushings to use for resizing my 308 brass.

This came about partly because I changed from Winchester to Lapua brass.

Also, because I have found that if you go from ( for example ) a 335 to a 334 bushing, you don't necessarily make the neck 1 thou smaller.

I keep using different sized bushings untill I get the sized neck I want.

Whether this is because the Redding Tin bushings are incorrectly labelled, or there is some other factor, I don't know.

Just my experiance.

Very likely the hardness of the brass. The newer ones will size as usual, but as you fire them and reload, they get harder and spring back more. Eventually, the case hard enough that it doesnt really move much.
