What Universal decapping die or combination of pieces works on tiny flash holes

[bluejay75]

Greetings gents,

Im having some problems figuring out what decapping die works best for Lapua Palma 308 brass, Lapua SRP 6.5 Creedmoor Brass and Petersen SRP 6.5 Creedmoor brass for the trifecta.

What size drill bit can i use to drill them all our and just use with my regular dies?

Any tips welcomed.

Mighty Armory makes the one I use.

The Mighty Armory PUA Decapping Die is a universal decapping die for depriming small flash hole cases with small flash holes. Recommended for use on all single stage and turret presses. Toughest in the industry!

Chuck your decapping stem into a drill and use Emory cloth to turn it down to the correct diameter. Done in under 5 minutes

Is the Lee Universal Decapping pin tough enough to hold up after this is done?

Another vote for the Mighty Armory Universal Decapping Die. They make both large and small flash hole pins that are super durable. No issues with my Alpha 260 rem brass, mix of 224 valkyrie brass, and 45-70 brass.

I ran into this issue with my Lee universal decapping die and Lapua SRP 6 CM brass. The pin was too big. I ordered a couple of smaller pins for the Lee from Brownells @ $3.95 each. In the meantime, I just used my Redding Neck sizer as a decapper and left the bushing out. Worked like a champ

Yes. I did it to mine

Sinclair universal has a smaller pin included for small flash holes. I wouldn’t run the die on a progressive press but havnt broken anything yet paying some attention

Mighty Armory!

I have had versions with and without the spring primer "flipper". I prefer the spring. Works effortlessly.

Lapua 6.5 Creedmoor brass uses a small primer pocket with an undersized flash-hole (.059”, 1.5mm – old “Gold Box” and current .062”, 1.58mm – “Blue Box”). Standard small decapping pins are 1/16" needle bearings, or 0.0625”, so smaller flash-holes may yank the decapping pin from the stem.

Hornady - Headed, Stepped, Decapping Pin Small .055" (#396618).
Redding - Undersized Decapping Pins 0.057" PPC (#01059).
RCBS – Extra Small Decapping Pin .057” (#9631).
SAAMI spec. for rifle cases, large primer, flash-hole = 0.078 - 0.082”. Pistol and rifle cases, small primer, flash-hole = .074 - .078,” but some European CIP (European equivalent to SAAMI) brass, such as Sako and Lapua may use 1.6-1.7mm (.059”) flash-holes.

Another vote for Mighty Armoury. They work great and it's really easy to change out pins when you bend one.

Another vote for the drill and sandpaper method. Did it with my Lee and never looked back. I also ordered a spare stem when I originally bought the die because a broken $4 decapping pin is a bummer of a way to lock up your whole bench.

Going to do it right now.

A spare pin(s) is always wise for the inevitable berdan case that makes it into the mix.

Thanks gents!!!

I turned down the pin in my Lee decapper about 15 years ago and it’s been holding up ever since.
