Alliant Sport Pistol Load Data

Just ran a doubles drill today. 100 rds with WST, then 100rds with Sport Pistol.  The slide was VERY hot after 80 rds of Sport Pistol!  I waited a few minutes to shoot the last 20 rounds, concerned my fiber would fall out.

 

Not a match scenario but it had me rethinking types of practice.

 

That is one nice thing about N320, it never does get very hot. 

 

Did you let it cool down between the WST then SP?

Yes, about 10 minutes so not to ambient room temp.  I'm planning to go again tomorrow with just WST and see how it fares over 200 rds.

You've never used Titegroup if you think SP gets a gun hot...

Interesting.  I haven't found SP to get my pistols all that hot...definitely nothing near TG, but I wouldn't even say noticeably more than N320 for me.  Did about 150 rounds through my G34 yesterday and 50 through my wife's P365 in relatively short order...I'd have described the slides as being warm after, but certainly not hot...

With the exception of the Sig P365, which gets hot no matter what, SP is NOT particularly hot for my guns and certainly not compared to TG.

I find it to be better in some ways and worse in some ways, aside from just price.  It meters better, is cheaper, and seems to smoke less to me.  I think that N320 seems to be cleaner, may have a slight edge in accuracy, and also makes less of a mess on my press while loading.  My view is that they are probably relatively equal, but one is half the price...

 

I agree that n320 doesn't seem to meter well...  I have never been able to figure out why...  Seems like all the granules are the same size, and my press (1050) is set up not to throw powder all over the place...  Yet the extreme spread and SD are never as tight as some other powders.

In 9mm, I haven't had too much of a problem with ES/SD using N320(N330 is even better, but doesn't really start running clean until at least 140PF), but I haven't had quite as much luck with 40 S&W.  It's usually at least twice what I get from Prima SV or CSB1M...

Personally, I would use up what you got of the 125's then your next batch start buying 145's/147's  I think you will like the way they shoot.

 

i've switched to summers 145gr .357" and have them dialed in: 3.3gr ASP, 1.110", is PF 130 out of my G19 (ave 898, SD 5.9, spread of 20). and yes, @csbelew i do really like the way they shoot!

 

something to note:  i had to switch back to the dillon powder funnel instead of uniquetek's M-style powder funnel. no amount of adjusting the powder funnel depth could keep me from shaving off coating of one (or two!) in three. the M worked great with summers 125gr, but i guess the longer 145gr had to be set just right not to shave. not worth the frustration.

Thought I would post FYI.  Shooting SC I don't chrono much, but I've started to shoot USPSA 1/month so I need a load for my 1911 that meets PF.  Also, wanted a common load for the 1911 (in USPSA) and PCC.  The 124 Bayou with 3.1 SP is my SC load.  It's very soft, but with a large ES, this with really beat up, much-used brass.  If I get ambitious I might at least repeat with like head stamp brass to see what I get.  The best load below for both the 1911 and PCC is the 145gr Acme with 3.0gr of Sport Pistol.  This is the softest load I've tried in the PCC and (barely) meets PF in the 1911.  What I find somewhat interesting is that like loads with the 145gr Acme bullets produce about 100 fps increase in the PCC, while with the 124gr bullets there is a 200 fps difference; I'm assuming that the lighter bullet exits the 5" barrel before extracting all of the energy out of the load.

 

FWIW, this data was collected with my Labradar which I hadn't used in well over a year.  Positioning the PCC was actually a bit less forgiving than the 1911 and for purposes of using this chrono a PCC is definitely not a rifle.  I positioned the muzzle in the same location as the 1911 muzzle.
