why is random fired case sticking in chamber...no heavy bolt lift

[CatShooter]

No one is suggesting that he set his F/L die to touch the shell holder. I said set it up to bump .002" on the shoulder.

Backing the die out .090" is not doing anything to the body of the case.

You haven't been reading his comments - backing the die out 0.09 DID do something - it removed the problem...

It seems new Norma brass a neck size and a trim will be the answer to no sticking and long case life. I will probably get a head space gage and measure up some of the New stuff after fired in my rifle. I will then try to set my fl dies to see if I can get all this once fired brass to the same dimension and see if it will work. I definitely learned something here. It is always fun to stick a few cases and split the neck on a few in you new hotrod .22 cal toy
At least I got to shoot it. I am amazed how hard it was to find new brass.

All of the not yet loaded cases of the same batch chamber fine. Could the bullet seating process be bulging the case body on the lower edge of the shoulder. I guess I could load one and measure it. If I recall I ran my seating die down to the shell holder and backed it off one round. Am I supposed to have a case in it and then run it down onto the case and then back off 1 round? I ran a case in it the way I had it and I feel no resistance. I thought rcbs instruction said to set it up this way. However I was wrong once before ;D

So your not taking the advice offered by a very notable competitor and others, who strongly suggested Full Length sizing. Neck sizing is fine if you stay in the lower nodes, BUT you stated you don't want a Swift that just lobs them out @ 3600 fps. The Swift is what it is.....if you're going to run them fast, then you have to get used to the concept that brass is expendable.....and it's cheaper in the long run to just replace it after a few firings BEFORE problems show up.

I have owned 220 Swifts since the mid 60's when I built them for customers... I have almost never been without a Swift of one flavor or another.

I don't accept the concept that you replace the the cases after a few firings... and I drive my Swifts HARD... ~3,900 to ~4,000, but I manage the cases like a surgeon.

... maybe loading for a .220 Swift is a black art

The .220 Swift is NOT a competition cartridge - maybe that is the disconnect here.

I figure neck sizing won't work the brass as much and fit the chamber better? ??? No I am not afraid to buy new brass! As soon as it is available I will hord!

 

[Swift4Yotes]

I have no plans to go out and melt her down. I want to get it down to .5" or better and only hunt coyotes and occasionally take it to the range to verify my zero and build some confidence. I am not having a plinking rifle shortage just ask my wife

The case does not have head space. The chamber does. I would suggest you purchase case length gages, that would be a gage that measures the length of the case from the datum/shoulder to the head of the case.

I would also suggest you re-read your original question.

( Re: why is random fired case sticking in chamber...no heavy bolt lift )

Fired cases? Pull the trigger, fire a case, the case sticks but there is no resistance to bolt lift. Again, I have rifles that make that problem impossible.

If you were adjusting the seating die down too far when seating you could be applying too much crimp. (Back to 'random fired cases), too much crimp could upset the shoulder of the case but the problem would be chambering the case before firing, not after firing.

Why is there no resistance to bolt lift?

I was referring to the fact that FLS a case everytime will result in a reduced number of firings as opposed to a case that is NS only and bumped only when needed.

 

[Swift4Yotes]

I understand what head space is but I believe hornady call it a head space gage. I can't go back in time to see if any of the cases were stuck upon closing the bolt and I am not sure I can duplicate the exact die setting. I am gonna set it up with case in the press and running the die down on case and the 1 round back up next time.

Backing the die out? For most that is a wild guestimate, but if by accident a reloader did managed to back the die out .090" and the die was a full length sizing die the reloader would have stumbled upon neck sizing with .090" of the neck un-sized.

If the reloader backed the seating die off .090" he would be a reloader that did not adjust the die correctly. A reloader will adjust the seating die down until the crimp portion of the die contacts the neck of the case. After contact is made the reloader only has to back the die to prevent crimping. 1/4 turn or .017". All of this depends on case length trimming, the length of the cases must match in length when crimping bottle neck cases. a reloader should never crimp when angry, I have heavy handled presses that demand attention to detail.

This is Benchrest theory from the '90's, and unfortunately still repeated in some of the current reloading manuals. Latest trend among almost every form of rifle competition is FLS which gives the following benefits:
* more consistent case volume between firings
* minimum upset in rests when working action > faster re-acquisition to target
* reduced tendency to gall lugs and abutments > reduced wear on action

I can't help but think that this rifle, though new, has some primary extraction problems. Any stuck case that you can remove by heavy hand force and with that much body taper, should be plucked loose with the primary cam.

Nothing like starting over.

running the die down on case

Give me a hint, what die are you talking about?

All of my presses have threads, all of my dies have threads. The threads on my presses and dies have 14 threads per inch, that works out to .071"+ per turn or thread. My seating dies do not have case body support, when I adjust my seating die down to contact the neck I am only required to back the seating die off, a 1/4 turn or .017" will accomplish that. When seating bullets in bottle neck cases I do not crimp. Before the Internet it was decided crimping can reduce bullet hold.

Methods and techniques, many reloaders have bad ones.

After reviewing rcbs instructions yet again it appears my methods have been text book and proper. I think I got some abused brass and I am confident as ever that my loads are safe and I am going to proceed as I was. I have learned a few things regarding neck bump and die setting. Thanks for everyone's input.

Neck bump?

If you are doing things like the "book" suggests, you did not learn much.

Good luck.

So Eric... he is not allowed to make a typo or mis-state a word, but you ARE???

How much "lead" should he have gotten from this disastrous thread. So much for helping a new guy.

I fixed it. About time you were helpful on the forum.

Sorry I am working as I type. Shoulder bump I mean.
