Sport Pistol in 9mm

[Bartojc]

I picked up a couple pounds of Sport Pistol before the holidays when someone had free hazmat. I loaded some up using RMR 124gr FMJRN and finally got a chance to shoot them today. I loaded 3 different charges, 4.0, 4.2, and 4.4. I my very limited testing SP charges seem to be close to my charges of W231 in weight. Anyone else notice this ? SP seems to be less snappy than W231 at least in my comparison today. Time to load some more up.

Sport Pistol takes a little less powder to achieve W-231 velocities. Good stuff IMHO.

Nice. I didn't remember that you had run them across the chrono. I guess Santa didn't get my list with the chronograph on it.

Definitely seems like a decent alternative to W231, maybe even better as it was cheaper. I need to shoot some more of it for sure.

I to have just started working with sport pistol and 124gr RN plated , did you have a preference of the loads you tested of 4, 4.2 , 4.4 ?
I ran the 4.0 124 gr plated from a G17 over my chrono , this load has functioned fine in 3 different 9mm handguns, I plan on testing at different OAL and at
4.2 next but all in all the 4.0 load worked and was accurate enough for punching paper and I agree sport pistol is very soft shooting ,

"Avg", "StdDev", Min", "Max"," Spread"
"1051" ,"18.8", "1014"," 1071", "57", 10 shots

4.2 seemed best for me in two pistols. I seemed softer than W231 I shot along side of it. I am surprised because even though I've heard folks talk about feeling the difference I never thought I would. I am going to load some more at 4.2 and maybe a few at 4.0 and try again. Loading at 4.4 definitely did not gain me anything for punching paper. FWIW my COAL is 1.135 with the RMR RN. Everything cycled fine.

I have never loaded that particular bullet with Sport Pistol, although I do know RMR and love their 124 Truncated Cone. I do use Sport Pistol for USPSA 9mm Minor loads. 3.5 grains under a Blue Bullets 135gn Truncated Cone @ 1.13 COL lit off with a CCI 500...good for ~990.ft/sec (133 PF) out of a Glcok 17.

3.3 grains did the trick for power factor, but the 3.5 grain load seemed more accurate to me out of both a Glock 17 and CZ75B....but then again I'm just some guy who plinks at local matches when I get the chance.

I've also loaded .40S&W with Sport Pistol with good results using 180 grain flat points from both Blue Bullets and X-treme. I'm liking this powder...which is good because I bought 8 lbs. of it!

I just loaded up some 9mm Sport Pistol loads to try out using the RMR 124 gr. JHP (or "MPR's" as Jake calls them).

The Alliant site shows a load of 4.4 gr. at 1.12 to get 1,087 fps out of a 4" barrel.

I made up a quick batch of 20 at 4.4 gr., but I am wondering now if I should have worked up a ladder and started lower. It sounds like Alliant published the Max loads on their web site, although 1,087 fps sounds about where I want to be to make minor PF and then a bit of a buffer.

I might need to make a few down at 4.2 and 4.3 as well, and probably even 4.1...

I just loaded up some 9mm Sport Pistol loads to try out using the RMR 124 gr. JHP (or "MPR's" as Jake calls them).

I loaded these a bit longer than the 1.120 Alliant data specifies for the GDHP.
P226 data:

124gr RMR MPR, 4.2gr ASP, 1.140 COL, Vel Avg 971
124gr RMR MPR, 4.4gr ASP, 1.140 COL, Vel Avg 1012

I did not redo these at a short COL that I settled on so I could shoot reloads in all my 9s. I do however have data from the RMR FP MW, obviously a different bullet but still in the realm of jacketed rather than plated. My measurements have the RMR MPR OAL .005 longer than the RMR FP MW.

124gr RMR FP MW, 4.2gr ASP, 1.140 COL, Vel Avg 1010
124gr RMR FP MW, 4.4gr ASP, 1.140 COL, Vel Avg 1036

Since I settled on the FP MW for all the 9s, I had to settle on a COL of 1.120:

124gr RMR FP MW, 4.2gr ASP, 1.120 COL, Vel Avg 1040
124gr RMR FP MW, 4.4gr ASP, 1.120 COL, Vel Avg 1075

That's just a tad over the 1071 that Alliant shows for the 4.4gr load with the GDHP. If you look at the 124gr FMJ/4.5gr ASP max/1.120 COL, that velocity is 1089.

I've found I needed to be at the upper end of the ASP load data for jacketed, but in the middle of the load data for plated or coated.

Here are my results from my SIG P320 X-Five (5" barrel) using 4.4 gr. Sport Pistol with the 124 gr. RMR JHP (MPR) rounds at 1.10":

Bullet Type: RMR JHP
Bullet Weight: 124
Powder: Sport Pistol
Weight: 4.4
COAL: 1.10"
Primer: CCI 500
Case: Mixed

Stats - Average 1126.00 fps
Stats - Highest 1140.00 fps
Stats - Lowest 1112.00 fps
Stats - Ext. Spread 28.00 fps
Stats - Std. Dev 9.67 fps
Avg Power Factor 136.93

A little on the hot side for USPSA, but not horrible. I like to shoot for closer to 132-133 PF, so maybe a grain or two less. The SDs are pretty good here, but then again I hand weighed every load.

I compared these directly to my "normal" TiteGroup loads (4.1 gr), and I felt that the TG loads were slightly more accurate. The SD's are higher here, but that is pretty normal for TG, plus these were made in mass production mode using my powder drop:

Bullet Type: RMR JHP
Bullet Weight: 124
Powder: TG
Weight: 4.1
COAL: 1.10"
Primer: CCI 500
Case: Mixed

Stats - Average 1072.88 fps
Stats - Highest 1109.00 fps
Stats - Lowest 1042.00 fps
Stats - Ext. Spread 67.00 fps
Stats - Std. Dev 18.47 fps
Avg Power Factor 131.49

I shot some Sport Pistol loads today. They have a bit more snap to them than my standard 9mm loads.

I don't have a chronograph so I can't report on that data. I'm going to drop down below 10% of max and work up.
