Thread: New 223

Yeah, standard 223Rem reamer, just driven another 7mm in. I guess the bottom of the case has parallel sized for a short section, not sure if this is going to give any issues, hasn't to date and I've now had 3 fires from some cases, they are still looking good.

Do you think if I just necked the parent case to 223, trim neck to just touch the lands and fire form from here using fast pistol/shotgun powder, I could get it done that way? If so, this would be the preferred method and I wouldn't need to neck out to 270 like I currently am. Necking to 270 is biggest issue I've had with crushing cases.

I did do a heap of reading on Cream of Wheat and fire forming that way, but was concerned about headspace. This is why I'm necking out to 270 and then forming the 223 shoulder in the right place. I had not considered trimming the length to touch.

Shooting the 68gr bullets tonight/tomorrow with the 2208 and will see how that go. weather is a bit shitty at the moment. Might walk to the 250m around the corner to see what James thinks about the whole thing too.
