Competition seater die problem...

[Gunsmoke]

Have a Redding 22BR comp. seater die. It looks like the die is crimping the case. I have adjusted the body up/down no difference. I leaves (sizing marks) about 1/4 inch down the neck. Help.....Also the stem leaves a good noticeable ring on the BB....I bought the set used ,,My dummy rd.neck measures .250 and the neck size bushing measures .248...
Any advice is Welcome....Thanks..This is my first set of comp. dies...

The neck in the sleeve is probably smaller than 0.250", I ran into this with my .22 PPC competition seater. The answer was to run my chambering reamer into the Redding sliding sleeve.

German..Thanks,, The chamber neck is .254,,would that work..

Yes, 254 will work but I have found this is the best place to control runout in bullet seating. - if you ream out too far the shell is not held in perfect alignment. If you can get closer, would be a little better (but 254 is close). It is my experience that the redding dies have very tight tolerance on bullet diameter but cannot do much to match everyones different chamber size so generally are a little loose in the collet. If you either machine the bottom end from your collet so the shoulder pushes up into the cone to centralise (instead of shell holder pushing up collet), or alternately (and hopefully in your "case" - pardon the pun), if you ream out the neck to under 1 thou tolerance, it will align beatifully. Even better is to use your reamer on a blank you can get from redding. that will hold shell perfectly but as you are already starting with a collet that is reamed to another spec it is likely too large in other areas. If you have the chamber reamer, a blank is the best way to go.
