bullet and pwd charge for 9 mm

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.

DITTO, COULDN'T HAVE SAID IT ANY BETTER. MY OAL IS 1.142 TAKEN RIGHT FROM THE VV MANUAL. JP

Sorry for resurrecting an old post here, but hoping JIMPGOV is still active. Curious as to what dies you're using for the 9mm 115 gr XTP loads. Bought a RRA 1911 9mm that had an impressive group on the test target using your loads. Having trouble getting those same groups replicating your load (5.0 gr VV330, new starline brass, Fed GMM, 1.142" oal). From a ransom rest at 50 yds groups are awful (4" plus). I'm using a Dillon square deal B and wondering if that's part of the problem. I have no issue making accurate .45 ammo on this same press, but really struggling with 9mm. Looking to set up a press that takes standard dies and wondering what you recommend. Thanks, Chris

I really appreciate the effort you have put into the testing and thanks for sharing. Have you tried any of the RMR 115 MW bullets?  RMR is my favorite vendor and I have had very good accuracy from that bullet but have never used the XTP’s.

YES , I'M STILL AROUND. I USE THE DILLON DIES ON A DILLON RL1050. BUT I DO NOT USE A CRIMPING DIE. I CRIMP USING A SIZING DIE. I DON'T RESIZE THE ENTIRE CASE, JUST THE TOP 1/16 TO1/8"  OF THE TOP OF THE CASE. ONLY ENOUGH TO REMOVE THE FLARE FROM THE SEATING STAGE. WITH MY MICROMETER IT MEASURES .377. SO REALLY NOT A TRUE CRIMP. IT DOESN'T DEFORM THE BULLET AT ALL.

RMR BULLETS ARE REALLY PLINKERS AT BEST. 25YDS THEIR OK. 50YDS THEY ARE NOT BULLSEYE ACCURATE. THEY WOULD BE FINE FOR THE RUN&GUN GUYS.

Thanks Jim! Really scratching my head on the RRA 1911 9mm accuracy issues. I'm following the recipe you gave me in 2019 at Perry, also listed in this post. The only difference is I'm using a dillon square deal B dies and using thier die for the taper crimp. I'm only removing the flare and crimp measures .377".
I'm going to try to get my hands on some factory ammo from Atlanta arms and see what kind of groups I get. Also setting up a dillon 550 and going to be ordering dies.
