Going from 38sc to 9mm

[zzt]

Some thoughts:  first, if you use SWMP or AA7 for 9 major, the case is not filled to the top.  Nothing slings out when the shell plate turns.  Second:  there are TWO advantages to 38SC.  One is it is a straight walled case.  NICE.  The other is case capacity.  HUGE.  You can fit any powder you want and a small fridge in there.  You CAN get it to shoot soft AND flat at the same time.  You can come close with 9 major, but you have to settle for one or the other, or some of each.  

 

All of the matches I shoot are lost brass matches.  Some actually are.  The rest are for me, because my back will not stand up to the constant bending.   So, 17 cents for 38SC to be used once and left, vs. 5.5 cents for fully processed, once fired,  same HS 9mm brass also left on the ground.  $1190 vs. $385 per year.  The $805 delta is significant enough for me to stick with 9mm.  If someone were to give me 20k 38SC brass, I rechamber one of my 9mm guns and shoot 38SC.
