9mm service pistol load questions

Post by C.Perkins on Tue Mar 08, 2016 7:57 pm

Weathers clearing and time to reload and shoot some ammo to get ready for the P100 and NIT at Camp Perry.

First off, the pistol is a 92fs with KKM slow twist 1/32.
My go to load has been Sierra 115gr Tournament Master over 4.8gr of VV-N340.
This load and Atlanta Arms AMU has gotten my 30pts, but need a hard leg.

Getting low on the Sierras and AA is pretty much depleted.

Have 115gr XTP's and some 124gr XTP's.

Question is does the 1/32 twist do better for 115gr compared to the 124gr, or vise versa ?(maybe does not matter ?).

Do the XTP's like more velocity, like over 1130fps or about the same ?

I know I have to try it out for myself in my pistol but was looking for info from those whom experimented already.
I am thinking to just load the same powder weight with the XTP's.
Any info will help.
No Ransom rest, just from my hand.
Powder will be VV-N340, Starline cases and CCI or Win primers.

Thanks;
Clarence

One of the more successful PPC shooters in Michigan uses 115gr XTP's at somewhere around 1200 fps in his 1:32 twist barrel.

I believe he's using WSF.

1-32 twist barrel use 5.0 of VV340 over any 115g jacketed round nose or hollow point bullet,  was recommended to me over on TT.

I have also had good luck with 5.4 of WSF.

Thanks gentlemen;

I have over 4#'s of VV-N340 dedicated to 9mm only.
Will start at 4.8gr(approx. 1130 fps)
Work up to 5.2gr(approx. 1200 fps)

Other slow pitch 9mm barrel fabricators?

Post by Mac2 on Wed Mar 09, 2016 11:58 pm

KKM has 9mm Barrels with a pitch of 1 turn in 32 inches.  Other barrel fabricators seem to stop at 1 in 16.
Any suggestions on sources for "slow" 9mm barrels?    Thanks,   Mac

The SIG P210 has a special "lead" barrel with a twist of 1 in 500mm, ½ the twist rate of the regular barrel which is 1 in 250mm. Any "lead" barrel will drop into any P210, all variations, without the need for special fitting or adjustment as the manufacturing tolerances are so exact from one pistol to another.

HERE'S THE PROVEN 50YD 9MM 115 &124XTP LOADS. I'VE SHOT THESE AT 50YDS FROM THE RANSOM REST IN 3 DIFFERENT,1/32 KKM BARREL IN 1911'S AND A 1/16 BARSTO BARREL IN A TONY KIDD BERETTA.

5.0GR VV330
4.8GR VV320
5.3GR WSF

PEOPLE A FRIEND OF MINE USES VV340 WITH THE 115GR XTP, 5.2 GR. I'VE NEVER TESTED IT MYSELF. BUT HE IS A HIGH MASTER PPC SHOOTER WITH THAT LOAD. JP

My loads are all +or- .1 grain except the VV330 only because I haven't found any for 2 years.  I've settled on WSF 5.4gr for my load #2 is 5.1gr of VV340 (cost).

I would add I load to an OAL of ​1.090" WSP primers, Starline brass, 115gr HAP or FMJ

- Dave
Initially brass gets a small flare at the mouth to allow the bullet to start into the case, bullet is seated to depth and then a small crimp is added to remove what was the small flare at the mouth. Basically the crimp is used to make the case straight again. I don't want excessive crimp on the case just enough to close the mouth.

Does it matter if you're using Federal vs Remington vs Starline vs Lapua vs some other brass headstamp?

I'm coming from the rifle world where going from one brass headstamp to another can significantly affect the optimal load.

I have a bucket of Winchester, a bucket of Federal, a bucket of mixed, and 1500 shiny new Lapua cases I bought on a whim during some Midway 75% clearance sale. Does 9mm headstamp matter in the bullseye pistol world?

OK, thanks, let me follow with a related question.

Should the "known proven" loads that get posted here be adjusted according to headstamp?

 YEP,  NEW BRASS AT 50YDS. IT DIDN'T MATTER WITH GROUP SIZE BETWEEN STARLINE, LAPUA,  HITRTINBEGER, OR WINCHESTER AT 50 YDS AS LONG AS THE BRASS WAS NEW. I EVEN HAVE A CASEPRO FOR ROLL SIZING BRASS. NEW IS STILL SMALLER THAN ROLL RESIZED BRASS AT 50 YDS. ROLL SIZED WAS ABOUT A 1/4" LARGER THAN NEW AND REGULAR RESIZED WAS ABOUT 1/2" LARGER THAN THE ROLL SIZED. IT DOES MATTER. JP

P.S. I HAVE NOT FOUND THAT WITH THE DIFFERENT BRANDS OF BRASS THAT I NEEDED TO ADJUST THE LOAD.

I can also recommend the Case-Pro 100, returns your brass to SAAMI standard, even heavily distorted cases due to oversized chambers. An example: using brass collected from various local ranges, cleaned, sorted and sized using RCBS dies I was only getting about 40-45% proper chambering in my Walther P88 and about 60-65% in my SIG P210-6 (slightly larger chamber in the SIG) after reloading. A lot of the brass collected was from once fired Swedish military M39B service ammunition. The brass is of high quality but when fired in the M45B sub-machine gun and some Glocks sometimes the brass was so deformed my RCBS sizer die couldn´t  reach low enough on the case being resized to remove all case anomalies which in turn prevented proper chambering of the reloaded round. Using the Case-Pro 100 I am now getting close to 100% brass reusability. It is rare the case that must be discarded and if so is usually because of another reason not related to resizing. The C-P is not cheap but will pay for itself in time (a suggestion: have your local club or range purchase one to help spread the costs) as just about all range pick-up brass can be refurbished for reuse, just remember to thoroughly clean your brass before Case-Pro usage and do not use on primed cases or reloaded ammunition. It can be had in a variety of calibers so you can tailor for your shooting needs. Hope this helps.
