First topic message reminder :

List: thinking of converting 38 tool head to 9mm...
What is a popular bullet and charge for this caliber?

I have found that in a Kart 1-16 that velocity is not nearly as critical as COAL and Crimp. I use 4.9 N330 with XTP 115.
That gives me 1100 fps. I have had very good luck with a powder that is very close to N340. 5.2 gives me 1215fps. Both are sub inch loads. For the long line I use new Lapua or JAG brass. As Jim has stated for crimp, just take the bell out. With my chamber, the magic number is 1.120 . If I go shorter the groups start to open up.
