Has anyone had the same problem as me when i came to neck turn my Win 300wsm brass for a light clean up cut.
I expanded the necks with my K&M expanderon,but when i slid the case onto the turning tool mandrel, the mandrel would not pass the juncture of the neck and the shoulder, A couple of extra passes up the expander allowed the turning mandrel to go past the neck/shoulder juncture but it was so tight there was no way you could turn it. /ubbthreads/images/graemlins/mad.gif
I ummed and arred about it for a while and decided to heat a case with my blowtorch and give that a try. HEY PRESTO it worked the case fitted perfectly over the turning mandrel.
I then annealed the remaining 99 cases,and i have had no further problems.(even though it was a long process.).
PS.before anyone asks if i have tried Norma brass,the answer is NO! not at £99 per 100 here in the UK (nearly $200) /ubbthreads/images/graemlins/shocked.gif
