What does this mean? What is the neck diameter of your vartarg chamber? What is the loaded diameter of your cartridge? dedogsit was over working the neck
What is your loaded round diameter? I would not use a bushing more than .002 smaller than the loaded round. Also, check the diameter after using a bushing die. The Reddings don't always size what's stamped.my bushing die is .227 the hornady die is .224 a shot casing measures .230
loaded .230 sized is .228
Sounds like you may need to neck turn. Loaded and fired by your posts are both .230. Thus, the difference between your loaded and the chamber neck diameter is equal to the "spring back" which is typically about .001. Do you know what your chamber neck diameter is?loaded .230 sized is .228
In my opinion, yes if one needs or wants to neck turn.im just wanting to know if there is a problem with neck sizing down to 20 cal with a bushing die?
does anybody know if there is a problem using a bushing die for necking down 221 fireball to a vartarg
