First off, great sight. I've read through lots of threads on this topic and there are some knowledgeable folk on here.
I have a .260 rem which I use a Redding Type s neck sizer for.
My lapua brass loaded has an OD of .294 and I have .291, .292 and .293 bushes.
.291 without the button gives reasonable results.
.292 with the button is rubbish, but still has an OD after sizing of .292 so I'm thinking the button is not expanding anything really and there is only light resistance on exit/up stroke.
Question is, do you think I should try a .290" bush i.e. who has had good results with 4 thou of tension?
Thanks in advance,
Normally you would go with .291 bushing if the loaded size is .294 to get around .003 thousandths
Some brass has more spring back and you have to go .001 smaller.
After you size one, mic. it and see what size it realy is and this may help you decide on a bushing.
The bushing dies dont use an expander ball so the up stroke should be light. What you are feeling is the spring back.
If you try a .090 bushing and it works you will be fine until you anneal your brass and then you
may have to go back to the .091 bushing.
