Well I finally got all the pieces to my 300 Whisper build and then the site goes down for a few weeks.
I'm glad it's back up so I can ask all sorts of questions.
I received a barrel that seems to have a very short throat.
I was banging my head against the wall trying to figure out why my rounds would not chamber and I kept looking to the cases.
It turns out that most of the bullets seated to the recommended length would jam into the lands.
I know this is typically beneficial for bolt guns or single loading semi's but is it still good for loading a semi through mags?
Here are some estimated OALs (I need to get a good ogive comparitor):
150 gr FMJ BT - 2.115"
168 gr milsurp BTHP - 2.127"
175 gr milsurp BTHP - 2.1"
208 gr A-Max - 2.2"
220 gr SMK - 2.227"
What kind of pressure curve/gas issues will I run into since I will have less internal space and therfore may have lower charge weights?
