6mm BR Case Sticking in Wilson Seater Die

[foxguy]

Ok I have a 6MM BR, Laupa Brass, 80 Gr Bullet
Brass has been sized pushing the shoulder back .002 (Harrell's sizing die 6MM BR).

Wilson Micrometer Seater Die 6MM B-R.

When seating bullets, the case (loaded round) gets stuck in the bullet seating die.
Sometimes I can pull it out with my fingers, other times.
I can pry it out with a popsicle stick and other times I have to use a small screwdriver to lever it out of the seating die.

The bottom of the seating die is starting to get a little nicked up from using the small screwdriver to remove the Case .

I plan on using a black felt marker to mark the case the next time I seat bullets to see if I can see anything on the Laupa 6MM BR Case.

I find this to be a little frustrating. I use a Harrel's sizing die pushing the shoulders back .002 thousands.
Possibly, I should anneal all of these cases before sizing next time to see if it helps this seating stuck case issue??

Has anyone else had this problem and what did you find to be the cause..


I will be shooting this 6MM BR this weekend, so I can investigate further next week.

Thanks for any other Ideas to check on this further.

Maybe the case neck is too thick?

I had this problem with some lapua 22-250ai brass..it was the area at the web that was sticking. Was also starting to get clickers with this brass.

Wilson will hone the seater for you for a better fit. You can easily do it yourself, too.

I've had that happen in the past with other cartridges, & generally it's the web that's snug.

Easiest fix is to take an appropriately sized wooden dowel, cut a cross slot in it with a hack saw, and slide a piece of emery cloth in the slot. Chuck it in a hand drill, and polish out the web area of the die.

I do a little at a time, hose it out with Brakleen, and check fitment, rinse & repeat.

As a finisher, I use a large brass brush wrapped with steel wool and covered in Flitz to final polish the inside.

Your shoulder bump should be fine. I would check to see if you’re getting enough sizing at the .200 line. If you’re not getting enough sizing in the web area mentioned above will be the cause of the case sticking. Honing the seating die, or a sizing die that provides more sizing at the .200 line I suspect will solve this problem.

Mine does that but lets go when I pull the seater stem out

I have had this trouble. Even though you bump the shoulder, are you sizing the full length of the neck?

I use Wilson bushing neck sizing dies. They don't squeeze down the neck all the way to the shoulder. Instead they go about halfway down the neck. After a number of firings, I full length size without bumping the shoulder excessively. This squeezes down the neck and cases don't stick.

+1 -> same for me. Almost like there's a slight vacuum created and pulling the seater stem out a wee bit breaks that vacuum...and the case just slides out on its own...

Glad to know I’m not the only one. But I can normally pop it with finger nail

^^^^^^^^
That's what I do.

I don’t know when they started, but newer Wilson seating stems are center-drilled to avoid this trouble.

I’ve had this in the past, chuck the stem in a drill and polish the inside of stem with 0000 steel wool, if that’s not enough chuck the bullet your having the trouble with in a drill and use some light lapping compound and polish inside the stem with that.

The seater contour doesn't match the bullet shape causing the bullet to stick in the seater rod??? My seater caused a contact mark all the way around the bullet ogive. I put valve grinding compound in the seater and a bullet in an electric drill. It removed the damage to the bullet. They may sell different seaters to better match bullet profile.

Webster: Pulling the seating stem up slightly after seating should show if that's what his problem is.

My buddy had the same issue as OP; not sure what he did to correct it (if anything.) Pretty sure he was hanging up near the cartridge base. I'll ask if I see him this weekend.

When I seat, I can usually (if it doesn't fall out on its own) eject the cartridge from the die by lifting the seater, and pushing it smartly back down (an additional step from what hfinkle and newbie said.) It allows me to eject them directly into the desired load box cell.

I put a hole in the seater stems that don't have them. -Al

Should be able to run empty brass into the seater die and if it sticks then it is the .200/case head that is causing the problem. If not then it could be the vacuum caused by the snug fit of the seater stem.
Or the bullet sticking in the seater stem

Does your problem occur with new brass as well as used brass. If so then the vacuum could well be your issue. If this only occurs in used brass then it could be that the bottom of the case is not being resized enough. I have this problem with my 6BRA. I use Wilson full length bushing dies to resize and I do it every firing. Eric Cortina sells a neck expanding mandrel tool and his mandrel holder is sized to bump the bottom of the case back

This sounds pretty typical as it happens often. It very likely just needs to be polished out a bit so the case drops out easily. No biggie at all if so. No noticeable difference or advantage to it being tighter than that. I want them to drop free with no resistance. I polish with 320 grit paper on a rod, in the lathe...pretty aggressively. I do this to prevent this very problem. You can also run the reamer in quite deep and it still works very well that way, too. I usually go about .010 over a go gage to be on the tighter side and a little more won't hurt a thing. Then polish until a well fired case drops free, if I have one. We all tend to try to get things just very near perfect but this is an area where a little looser is more near perfect than too tight is. Kinda hard to hit it perfectly right unless you have a pretty tired case to work with when cutting the die. But, if a fired and unsized case drops, a sized one should too, and be just about right.
