Questions about forming 22BR cartridge

[afret]

I'm using Lapua 6BR brass and trying to make it into the old style Remington 22BR brass. I've used a new Redding full length die and then used an old Bonanza 22BR die on the brass. It takes too much force to just use the Bonanza die alone. I took out the expander on both.

I've trimmed the brass to 1.51". I have to neck turn the brass yet. The chamber neck is 0.248 measuring fired brass from this rifle. I turned one piece of brass to 0.011 neck thickness and seated a bullet to test the fit in the rifle. The bolt works with no added resistance so I think I'm on the right track.

The question I have is after using the expander mandrel and turning the brass, should I put it through the full length sizing die again? And should I anneal it again before sizing? Thanks!

I used to use a Redding standard seater die as an intermediate for necking down the brass. Worked great! First shot is fireforming so I just shot mine. FL sizing would be fine as well Imho.

I'd anneal it after the sizing and turning, might be better to do it before turning but to me it doesn't seem to matter too much. I did a 20BR a few years back so I went through all these steps plus myself. If it'll fit in the chamber I'd go ahead and load up some junk rounds (low end powder charges under a bullet touching the lands, I used cheap Noslers) to fire form it. Only reason to size it again is if it doesn't have a enough neck tension to hold the bullet.

Biggest part I found was the annealing after reducing the neck, since I went from 6 to 22 then to 20 I found it really made things go smoother, never lost a case.

Thanks for the advice. I'm going to go ahead and anneal them.
