Working up a load for the 22-6MM and everything was fine until this morning Shot a five shot group that was decent Went to load 5 more and started crushing cases to a mushroom at the shoulder I haven’t changed anything from the last time which was yesterday All cases were sized and primed at the same time so there nothing different about them Took the die apart and cleaned and everything is moving smoothly What has happened ?

Is the expander ball too close to the neck sizing area of the die. Forster dies are designed to have them expander ball right under the neck but if they ball is too high at will crush the cases.

This is happening when I’m pressing the bullet in I had already pressed around 25 in with no problem and this just started

Get your micrometer or calipers and a strong light and recheck before you crush another case. Wes is correct about Forster dies. If it were only one I could blame Murphy but 5 somethings off kilter somewhere. Same brass lot? If so you could have 'soft' brass.

Same brass lot Same everything I just loaded the remaining 4 of 50 pieces I ruined 10 pieces I did chamfer them deeper inside and outside Bullet pressed in perfectly These are Hornady dies Very limited choice when it comes to this particular cartridge

RCBS seating die? These dies are designed to crimp or not crimp depending on how you set up the die.
Have you trimmed all of the cases to the same length? If these cases are longer and you didn't set up your die properly it may be trying to crimp the case on the bullet. But if there is no cannelure to crimp in it may crush the neck into the shoulder.
Just trying to guess at the issue.

These are Hornady dies I prepped all cases at the same time and they are all the same length The seater die is set up per spec’s I’ve been doing this more than 20 years and have never encountered a problem even remotely close to this To load and fire as many as I have since Friday morning and this happens with the same set up is just plain weird May be something to with being 6MM cases necked down to .224 but what I can’t find especially since they all mic the same and most all have loaded perfectly

I'll go out on a limb have you measured the thickness of the walls at the case mouth Yes I’ve mic’d everything Right now I’m leaning towards the inside chamfer not being deep enough and the bullet pushing the case neck down into the shoulder I will say the bullet was pressed in each case that mushroomed I’m thinking it was just too tight to start seating the bullet and it crushed the case Since I’ve chamfered the inside a little deeper I’ve loaded 6 more with no problems

I'm sticking with my bad brass guess. I've loaded for 40 years and never has that happened. When the cases were made I'd bet the shoulders weren't properly formed and got brittle. Has some Winchester 30/30 brass you could only use Ball or Spherical powder otherwise the mouth would twist&turn goofy upon clambering. 30/30 brass ain't the strongest design so I chucked it up to the same thing this is Just one them things.

Very possible but could that be possible when they all came out of the same bag ? I’ve never been stumped with a reloading issue until now and all I have is guesses

Did you anneal the cases? When forming brass to a different caliber it's a good idea to anneal them.

No issues with any of the brass I’ve already fired so I’ll just chalk it up to bad brass or n that lot

I had something similar happen several months ago. I just happened to take a pipe cleaner and just touch a bit of lube in the case mouth and they straightened back up. I could feel it when it was going to happen. It didn't happen on the second round of loading at all.

You might want to push an empty case without bullet up into your seating die to make sure there is no resistance. It sure sounds like the neck walls are too thick on some of your brass. There are variations in the best of brass. If the walls are too thick, then neck turning is your answer. another thing to try is to raise your die a 1/16" and lower your bullet seating stem to compensate, Let us know when you get it worked out.
