Skip's Shims

[AlNyhus]

For those that can't savvy a shim but don't want to hassle with conventional lock rings, these are great. Lightly snugged, you can adjust the die but the die won't rotate as the case is sized. Witness marks per your whim.

Good shootin' -Al

Presses flex on when sizing. An indicator proves that.

OK. How much?

And that's in the press frame. What does that have to do with a steel die against a steel shell holder?

Show me how you can stick a .002" shim between 2 pieces of steel in hard contact.

So you remove a shim and flex your press frame an extra .002". If the dimension changes in your brass it's one of 2 things.

1 - your brass would have reached the dimension you wanted even if you didn't change shims.

2 - you already sized it once and if you'd just sized it again the same dimension would have resulted.

Again, you guys can't convince me a steel sizing die and a steel shell holder change dimensions if you just smash them together in a press harder.

Now, having said that. If there is a gap between your die and shell holder and you're changing shims while a gap remains then that's another circus and group of monkeys. But that's not what at least some guys say they are doing.

That’s the point…….

When you make hard contact or camover, it takes all the other movement and flex and brass inconsistencies out of the equation.

Put a +10 shell holder in, no bump, go +8, no bump, +6 gives you a .0005ish bump, +4 gives you a.002 bump, your set.

I keep a rubber O-ring under my lock ring. Put the die in till there’s a good contact. You can even fiddle with how hard it contacts to finely tune it and the die floats a touch but never changes position.

Steel to steel. Good annealing, lubing, and press strokes and each and every piece is identical to the capabilities of my caliper.

How other people get absolutely perfect bumps over 100 cases without hard contact I guess you will have to convince me.

I like to cam-over, so don't use shims with sizing dies. The Redding competition shell holdrs are perfect for adjusting shoulder bump to .002" or less.

Shims and comp shell holders together work great for precision priming with RCBS ram prime though...

 

[LHSmith]

The Redding competition seating dies are perfect for adjusting shoulder bump to .002" or less.

You may want to rewrite that -people are confused enough as it is. Unless seating dies can now do sizing also.

Apparently shell holders work completely opposite of die shims then.

Do you realize that the thread title is Skips Die Shims and not Jim's shell holders?

I don't know what you're talking about.. looks ok to me Thanks for the heads up. Dog's were barking at a squirrel and was texting a buddy on the phone at the same time.

Can't speak for others, but I initially set the dies so they just touch the S/H and I have to make sure I use the very same S/H with that die. My Redding Boss presses do not "cam-over" in the same manner the Rockchuckers do.

Skip the shims, got it, thanks, I do. Who’s Jim? And they do opposite things, yes.

Did you mean " Redding Competition Sizing dies" and not seating dies?

 

[jccinohio]

Did you mean " Redding Competition Sizing dies" and not seating dies?

Actually meant competition shell holders. I use the Redding S dies with the competition shell holders and get my bump to within .002" of fired. This is using a RC and cam-over. If I didn't have cam-over I'd prob be doing Skip's shims

OK, so sometimes good sarcasm is just lost.

My point is the thread was started to discuss die shims. Given that there are shell holder sets that work completely opposite of die shims do you not see how this would complicate a misunderstood topic even more?

If you want to talk about shell holders then why post in a die shim thread?

Sarcasm is lost indeed…

 

[Murray Brook]

I use both the shims and Comp shell holders and I find that both have their place on a reloading bench. The shell holders are a little faster to use but with the shims you can tune the accuracy/shoulder bump a bit more. JMO

But...have you tried it yet? I mean...I read this same stuff over and over and can only think you're the only one that doesn't know. Sorry, but true.

No, that sounds like way too much trouble to me too. Lol! I think these are what I bought.

Amazingly place. McMaster in Aurora Oh was a customer of mine for probably 20+ years until I retired. Warehouse was huge and they built another huge warehouse for one off large items across the road

Well I guess I deserve that even if it's not true.

I can't argue that. Shims are ordered so I will test them when they arrive.
