Do you crimp for your semi .223?

My dispenser is coming around , I just made 10 rnds ,23.8 to 24.4 gs powder. Out of 10 shots fired I had one , where the bullit got pushed back into the case. Shooting at a 6 inch target, 30 yards,open sites .all were in the center. So 9 out of 10... Not good?
 
well you have a spreed of over a half a grain of powder and in a 223 that is a lot. You will find that out for yourself when you move out to 100 yards as 30 yards isn't going to tell you much at all.

Ya, I thought as much, just wanted to test the cartridges, I'm keeping well below max , until the charge is more consistent.

It was the third rnd in, felt like a ftf, when I looked , the rnd was kinda jammed in the feed ramp, I pulled back the charging handle and it fell loose. The tip was pushed into the case , with only the red polymer tip showing . There's a pic of one just like it in XCR FAQ thread ... Second last thread

did you crimp them when you seated the bullet?

I'm gonna say no, cause I only have a 2 die set. From the research I've done, crimping the.223 is not common and shouldn't need to be done. That's what I've read, but is not my opinion. Would I need a die for crimping?

Would the lube from resizing cause any problems. I'm thinking I should tumble them again after resizing?im more concerned with inside the case neck.

Semi-auto. Crimp it.
The guy beside you and your family should appreciate your diligence.

Powder dispenser:
A) Not being used correctly.
B) Not accurate enough to rely on.

the rbcs dispenser in brand new and came assembled it does seem to be the issue I've been checking loads all day I can now get 10 in a row with -/+ 2. It's a basic setup. Also the scale needs to be re adjusted every so many loads.its also a new rbcs 555. As for the crimping, I ordered a 2 die full lenght rbcs set. I didn't get the crimping die because , I've read it's not necessary for .223. But if it makes it safer,I'll definitely get one....thanks
 
Ok ,I have another question. Do you crimp your semi .223 rnds? why or why not? I had one set back bullet ,out of ten rnds, and after researching the net, it's 50 50. Also thers a post in the XCR FAQ thread , on the last page, it shows a pic of , what looks like a setback rnd. The poster said it was AE ammo.

I crimp all my .223 ammo. Try the Lee 223 Factory Crimp Die (#90817)
Higginson Powders in Hawkesbury, ON should have one in stock for about $16. They are a Lee Distributor and usually have all Lee products on the shelf and ready to ship.
The Lee Factory Crimp Die is adjustable and will crimp any bullet even if it has no crimp groove.
 
Some dies have a built in crimp in the seatng die, case length has to be trimmed to uniform size for it to work properly. When you seat the bullet, it crimps the bullet on the end of stroke. The lee factory crimp die is more forgiving with not so uniform case length, but is another step in the loading process. I use the lee crimp on all 223's for semi autos
