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.

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...

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.

Just some more data points for Alliant Sport Pistol:

147gr Blue Bullet TC 0.3555 loaded to 1.14 OAL using mixed brass"

Crimped to just remove bell

10-15 discard rounds loaded in between powder adjustments 

CCI Small Pistol Primer

Sig X-five Legion

70 degrees F

Average FPS of 10 shots

Loaded on Dillon Super 1050 with powder baffle, SSI funnel and micrometer adjuster

Velocity measured via magnetospeed V3 



3.0gr=860fps S-D:7.0 PF:125

3.1gr=882fps S-D:9.1 PF:130

3.2gr=897fps S-D:6.7 PF:132

3.3gr=926fps S-D:9.8 PF:136

3.4gr=939fps S-D:14.7 PF:138

Overall very satisfied with this powder. It's pretty clean, doesn't heat the gun up a whole lot, not smoky, meters very well, and seems to burn pretty consistently.

I don't see much 115gr Blue Bullets data out there.  I'm looking to make some sub minor loads for this year for Steel Challenge.  Any starting points someone can share?

I don't shoot steel challenge.  What I do know is my 115gr load is 4.5-4.6gr or SP which gets me around 140pf ~1200fps out of my 16" MPX barrel.

I tested some 115 blues in my AR-V PCC (this is with the Taccom barrel that is essentially pistol length)

 

Chrono: ProChrono with indoor lighting kit (i was at my indoor club and turned off all the lights around the chrono)

Bullet Brand: Blue Bullets

Weight: 115gr (but I measured some serious weight deviations from 114gr up to 121gr)

Powder: Sport Pistol

Charge: 3.1gr

Primer: CCI

OAL: 1.12

Vel. High: 913

Vel. Low: 803

Average: 858

Spread: 110

SD: 38

Avg. PF: 98.7

 

I was careful in measuring my charges and verifying OAL.  I am almost certain that the massive deviation and spread was due to the inconsistencies in the bullet weights.  I only ordered a sample pack so maybe that isn't completely reflective of their QC.  

 

The same day I also tested the same Blue Bullets with a different powder (Clays) and had similar results with a 36 SD and a spread of 101.  Same day I was also testing a different manufacturer's 115's and they, too, were all over the place with weights.  Very similar results as the Blues with large spreads and deviations.

 

In all fairness to the chrono results, I was using mixed range brass.  But, all of my chrono results over the years have used the same mixed range brass and I have NEVER had deviations and spreads like these.  I'm just going to stop mucking around and stick with what works for me.  I'm sure I'm not the only one that keeps screwing around with load development when they really don't need to.

Amen.  I've found that SDs don't come down until pressures go up.  So I've given up on mouse fart loads, especially for PCC.  They are just too dirty and inconsistent.

That and for Steel Challenge thinking about those slow speeds and the 35 yard targets.  While mouse farts are sweet to shoot, they sometimes feel less than functional.  From here on out I'm just going to keep going with my 124/125gr. loads with a charge that is still sub-minor, still easy recoil but I know will still have some power behind it.  

 

I tested some of those really low loads in my CO gun and the brass barely made it out of the gun (in a couple of cases it didn't).  I already have light springs in there and I'm not going to lighten it more.  I try to use the same load across all my platforms, this way I don't grab the wrong ammo by accident before a match.

Thanks to both of you...I'm going to try some loads starting in the high 3gr area and not down that low, hopefully it will be semi consistent.  If not I might just stick to 125gr that I will be using in my USPSA PCC and drop the powder down a few .1's of a grain so it's slightly lighter...will give me one less bullet to stock as well.  Hoping to try Saturday if weather cooperates.  These 115's are some tiny bullets.  Loading at 1.1 OAL" they are so lil and cute :)

For those interested I loaded and chronograph a couple loads using 135 grain BBI bullets. I didn't think to take any pictures of my groups, but the accuracy is very good. I loaded 3.6 and 3.7 grains. below are the results.

Did the same this morning in SLC, UT (approx 4200' ASL, around 80 deg) with a Labradar.  135gr RN Summit City bullets, 1.115-.120 OAL.

 

3.5gr load 7 shots had 986 fps average, SD of 10.9.

 

3.6gr load 7 shots had 1012 fps average, SD of 13.0.

 

The bullets weigh a touch light (134.5 or so) so looking at 132/3 PF for 3.5gr and 136 PF for 3.6gr.

 

Just switched from 124s and Win231/HP38 (4.2gr load).  Dot return is definitely slightly better with the 135s.  Sport Pistol is a significantly cleaner powder, at least in the loads I'm running.
