Ok so I’ve beeen reloading for some time ....I consider my self ok in this hobby.....
So here goes ..
So when I do brass prep I do 100 plus at a time ...I’m talking rifle here
So like everyone else I go throu the stages ...I check and double check length ...and put throu a Wilson case guage .....
So when comes time to load up ...seat the bullet and put a slight roll crimp ...look for that 1000, ..2000ths crimp follow the instructions and bingo got it !! Done
Go do a couple of other cartridges bingo all is great
Do a couple more ..and son of a biscuit!!!i crush/push the shoulder back
Mother floocker!!! WTF !!
All cases where trimmed with my rt-1500 Dillon case trimmer
I don’t see we’re I went wrong ....
Any advice....ever happen to you folks
Help
Thanks people for your opinion and advice
 
Mainly for 308...just to say I have the lightest crimp ....when seating and crimping in one step
That slight ...”cam over “ feeling
Or am I going about this in the wrong way

Do you have a roll crimp die????

normaly 308 is just a seating die

lee makes a factory crimp die for 308

Most people for 308 do not crimp or use the lee crimp die
 
New brass or 1Fired? Fired in your rifle or someone else's. What brand of new brass?

This happens sometimes with new brass. Happened to me with 300WSM brand new winchester brass. 2 cases out of 50. My guess is shady quality of brass in a given lot.
 
Could be a couple of things.
Unless you have a cannelure on the bullet, skip crimping, or buy the Lee FCD and do it in a separate step.
Neck thickness varies, so a thicker neck can cause your crushed neck/shoulder.

Click to expand...

Always seat and crimp in separate operations and you will not crush the shoulder.

And on a bolt action a crimp should not be needed, and if needed to increase bullet grip you can polish the expander down smaller to increase pullet grip.

NOTE, at the Whidden custom die website they sell expander kits with five expanders from bullet diameter to .004 under bullet diameter.

Example below is a Lyman type "M" expander for a .223/5.56 and it is .003 smaller than bullet diameter. And the average expander is only .001 smaller than bullet diameter. I use this Lyman expander on my AR15 ammo and do not crimp the bullets.

Your seating die is not set the same as your resizing die. My buddy did this and the bullet would not chamber because it made a small bulge in the neck.
 
I thank you all who respondid.......I respect all advice ......
Looks like I’m doing it in two steps from now on and with a lee crimp die ....to avoid my little problem
Thank you all thank you all
Sometimes it takes another view to help see what the problem is ....and to help find a solution

For that caliber I would just back my seater out a rev, so it does not crimp (if it had been crimping) and use it to just seat the bullet. And I would skip the Lee crimper. I love that die, but no need for it in your caliber/rifle.
 
I don't crimp my 270 loads. Neck tension is enough to hold things in place. As Ganderite said, back out the die a bit so it doesn't apply a crimp, and just use it to seat the bullets and be done.
 
Had this exact problem with .223 - went and bought Hornady dies, so I'd have the best - had to crimp as the bullets were loose in the cases, but turn-down the dies enough to crimp and NEW SHOULDER!!! - one I was pretty sure, would not chamber. I may have thought of a rude sailor word or two...

So, bought a Lee collet die and problem solved. If anybody's interested, I have half-a-box of .223 with a couple of extra shoulders that I'd be willing to part with... :(
