Redding 'S' Full length bushing dies-bushing size for .223?

--------------------------------------------------------------------------------

Title says it all...

Following the instructions in the Sinclair catalog...

" .002in smaller than the average neck diameter of loaded cartridges.

My .223 reloads average 0.252 inches neck diameter.

Therefore, 0.250in bushings are the size.


Anyone disagree?

Suggestions?

I'm replacing the Dillon sizing die on my 550 -

Decapping pin with expander ball pulls apart at the stem connection.
I believe the thread is shot.

I love the Redding Competition die - consistent and exact!

Should have bought the set.....

TIA

Just for reference, my bushing is 0.245" diameter. I measured 0.248" overall diameter of my loaded rounds using commercial Winchester brass.

0.245" case neck
0.224" bullet

0.024" neck wall thickness (2 walls)

I hope this helps in some way.

You need to measure your loaded rounds with each brass mfg you use.

Each is different, and hence you will be in need of several bushings...

Hmmm...I think I may reconsider and test Dillon's "no BS" warranty!

The neck tension on my Dillon sizing die never posed a problem...

until the stem threads failed!

thanks

Dillon pulls thru again!

Discussed my take on the problem with customer support....

They suggested I blue locktight the decapper pin to the threaded stem.

I let it cure for about 2 hours.

Ran thru VERY well lubed cases - Pin pulled out on the 5th case!!

Spoke to the same support guy...

Decapping pin with expander ball AND a new stem is in the mail!!!


Dillon's support with their "NO BS" warranty - the best in the business!

+1 for these dimensions are more consistently found for commercial and much LC brass.

I remember taking quite a while to decide which bushing to use. I use the 0.246" size bushing and do not do any neck expanding or crimping. I have had great results at 460 yards using this setup (with the competition seating die) on about 1k rounds through my 24" Bushmaster. It loves 55gr and 60gr Hornady V-Max bullets. I might try a larger bushing down the road to see what happens, but I'll bet I would experience insufficient neck tension if I were to use the 0.250".

The thickest commercial brass I have ever encountered gave me a .248-249" reading. I used a .247" bushing. It had plenty of tension.
