Hello;

I'm NOT new to reloading but this is my first attempt to reload .223 with boat tail bullets.

It seems the diameter at the mouth of the case is wider then the .223 (224) bullet causing the bullets to fall into the case during the crimping stage.

I have adjusted the depriming/sizing die without success. It was lowered enough that it actually buckles the cases at the shoulder before changing the diameter of the mouth. After raising this die slightly (just enough not to cause damage)the mouth diameter is unchanged from its spent condition.

After the charge station is complete, I can manage to rest the BOAT TAIL bullet in the case and correctly seat it, however in my opinion it is to loose and with little pressure during the crimping stage the bullet fall into the case.

Is this a common trait with BOAT TAIL BULLETS?

Other things to consider;
I am using once fired remington brass, all cases are well lubed and measured, Dillon press with Dillon Dies,

I look forward to solving this problem,

Thank you in advance for your help.
 
That is very odd. Did you measure you bullets as well as the outside/inside neck diameter after sizing? I just loaded up 250 55gr fmj's in random range pickup brass with no issues. I didn't do any crimping though. Not like recoil is going to set bullets back.
 
Hello Kman

Thanks for your suggestion.
My digital caliper only measures to the hundredth's of an inch. This is what I have just measured. The case inside= .23, outside=.25, bullet= .22

The actual bullet is the hornady .224 55gr b/t with cannelure Part # 2267B

What is your total height of the round when completed?

I have seated my bullet enough so that you can barely see the forward most part of the cannelure giving it a total length of 2.22.

Thanks again

From what you wrote your necks are only 10 thou thick
has someone turned these necks ?
 
Since his calipers round to the nearest 10 thou they could actually be up to 18 thou thick, he needs a set that will measure to the nearest thou, not tenths.
 
This is not a result of using boat tailed bullets, it's a case of incorrect sizing,which could be due to the dies being set up improperly, or defective dies.
