I am having trouble with the decapping pins from a type s die sticking in my Lapua brass flash holes when resizing. I have tried tightening
the expander ball with pliers and using JB weld to hold it in, and nothing is working. Do I need to ream out the flash holes?

What size primer pocket. The small primer pockets use a smaller pin than the large pockets in Lapua brass at least in some calibers. You may be able to just switch to the small diameter pin .

For the small flash holes in Lapua brass. I may need to find a Sinclair .625 flash hole reamer or another kind of some equivalent make. Sinclair is out of them. Any recommendations?

If you're brass is 6 mmBR then I would recommend getting a Sinclair decapping die and leaving the flash hole alone. Again, if you are talking about the 6 br then your Redding die should have come with the smaller pin, but mistakes have happened.

You may not have the correct pin size in your die. Which cartridge? What's the size of the flash hole, that comes from Lapua, without opening it up?

"Gosh darn it" Abe, learn to read the whole thread. Or maybe we're all on your ignore list?

Some Lapua Small Rilfe primer cases come with about .060 flash holes -- sometimes .059, they're metric. The small decapping pins with Redding assume a .0625 flash hole. That's why Eric Sinclair came up with the reamer, the "Possum Hollow" brand, which removes only a whisker of brass.

Usually.

It's that "usually" that makes it another good idea, after reaming about .0025, they're all the same size. No one is talking about taking the flash holes up to .080, the typical "American" size.

If Sinclair is out, try

Or, another brand,

If everybody's out, I suppose you could get the RCBS PPC primer deburring tool. I don't know what size it cuts the flash holes to, in fact, it may be too small to clean them up, since it's primary purpose is to deburr the flash hole inside the case.

Some folks, depending on the caliber of their cartridge and the quality of the brass used, may want to leave the flash hole as is.

If I recall correctly, Jack Neary is an advocate of leaving the Lapua .220 Rusian brass flash hole at the original .059" without the need for uniforming because it's manufactured to a higher standard, and apparently others feel the same way too [See Below].

However, if you feel the need to ream, here is another tool: K&M BR Inside Flash-Hole Uniformer Price:$11.00
Source: http://www.6mmbr.com/catalog/item/1433308/900728.htm

This is a great tool, very easy to use. It gives repeatable results each time and, at $11, it costs about half what some other (less effective) deburring tools cost. Moreover, it is self-adjusting, and you can switch the cutting tip between small (for 6PPC/6BR) and regular (for standard diameter flash-holes). The deluxe "professional" version with a metal handle is available for $15.

Note: This tool is primarily recommended for those people using Remington brand 6BR brass, 6XC brass, or other calibers like 22-250. We recommend that you leave the Flash-Holes alone with Lapua 6BR and 220 Russian brass (used for 6PPC). The Lapua 6BR cases come with a .059" Flash-Hole, and the K&M tool will ream the holes to approximately .064-.069" depending on tolerances. This can be useful if you must use a 1/16" (.0625") standard decapping rod. However, the best thing for Lapua 6BR brass is to use a die with a .057" decapping rod, such as the Redding, Wilson, or Harrell's.

Using the tool is simplicity itself. Just feed the cutter into the case until the tip exits the flashhole and the cutter depth-stop contacts the inside base of the case. Then, holding the sliding cone against the case mouth with your first two fingers, give the knob a twist or two. It's fast, precise, and pretty much fool-proof. You can't ream too deep because a ring around the cutter tip bottoms on the case interior before you go too far.

With that quick turn or two you simultaneously "ream", "de-burr", and "chamfer" the inside of the flash hole. One great feature of the K&M tool is the "pre-set" depth stop surrounding the steel cutter. Because cutting depth is set off the inside of the case, not the case mouth, you can deburr cases of any length--they do NOT have to be trimmed to length first. And with the handy sliding centering cone, you don't have to fiddle with set-screws on cutter depth stops or buy different pilots for different calibers. The simple two-way sliding metal cone keeps the case aligned and centered as you deburr and slightly chamber the inside lip of the flash-hole.

You can order the tool from Precision Reloading, or order direct from K&M Services, (717) 292-3175.

And, it appears the Palma Team has evidence that the .308 performs better when that caliber brass uses a .059" flash hole that it is now being produced: http://bulletin.accurateshooter.com/2009/12/308-lapua-palma-lapua-to-introduce-a-small-primer-308-variant/

Note from Lapua [ http://www.lapua.com/upload/downloads/brochures/lapua308winpalmacase2010.pdf ]: To achieve their ultimate in accuracy potential, Lapua’s .308 Winchester Palma cases utilize the same small diameter flash hole found in our .220 Russian and 6mm BR match cases. For proper depriming, the decapping pins in many makes of reloading dies should be replaced with the smaller diameter pins intended for the .220 Russian/PPC or Lapua 6mm BR cases. Failure to do so may result in sticking the decapping pins or damaging the flash holes.

So, with some cases, running off and reaming, isn't necessarily required; it depends on the quality of the brass. I use Lapua 220 Russian and 6mmBR cases for my 6PPC and 30BR. For me, it has eliminated another chore. :)

I use a Lee depriming die set up in this press for all my depriming, http://leeprecision.com/reloader-press.html , so when I was faced with the tighter flash holes, I just took the rod out of the die, chucked it in my bench drill & polished off a few thou from the pin with a safe edge file, finishing off with emery paper. Works a treat & all the grit stays away from my expensive presses & dies.

If Redding doesn't make them (I think they do), get some Forster pins. They are .062 at the top to be held in the assembly, and .055 on the business end.

If everybody's out, ....

A few years ago Lapua 220 Russian brass had a 1.5MM flash hole. 1.5MM is 0.0590". About 2006-2008 Lapua started making their flash holes 1/16" (0.0625"). In a pinch you can go to your local mill/tool/hardware/Travers Tool/MSC/etc, and get a #52 drill (0.0635") and drill them out, carefully and use the normal 1/16" decapping pin.

Somewhere on an old computer I still have the email from Nina Ideimola at Nammo Fl verifying the change. (At that time Nammo in Finland was the parent company of Lapua.) Now Nammo Lapua/Vihtavori is owned by a French company who doesn't have a clue!! The VP over that group recently told me "yes, we now own it but I don't know what our future plans for it is"!!
