man this is complex. what case length should i use?
i'm about to start converting my .222 and .223 cases to 300/221.
the gunsmith hasn't finished with my barrel.
do i have to wait for the barrel and then try to measure what the my overall case length is? i bought the reamer based on some suggestions from this forum, but i don't remember where from.
lot of misleading info on the web
1.4" = 35.56mm according to
http://www.ar15barrels.com/forming.shtml
1.35" = 34.29mm according to
http://en.wikipedia.org/wiki/.300_Whisper
anyway. i trimmed my cases to 1.4. i'm not going to reload anything until i can try to fit it into the barrel
