Thanks for the info. I think 3.8 will be low but just want to be on the safe side.I figure I?ll probably end up around 4.2 or 4.3.

Just picked up some at Bruno?s in Phoenix. They asked what?s going on this stuff is flying off the shelf. I?m going to load up a ladder this weekend using Berry?s 124gr HBRN starting at 3.8 and working up, OAL will be 1.125. Does this sound right?
I just had a buddy pick up a pound from Bruno's while he was down in the valley.   It was on sale for 20 per pound.

I'm going to work up a 40 load with my 165gr rnfp plated bullets.  I may also work up a load with some 180gr rnfp plated as well.

Cheers,
Toby

Copper plating is thinner and thus more malleable than a copper jacket and should obturate better than a copper jacket, and better obturation means higher pressure when all else is equal.  I suspect plated bullets obturate more like lead than a jacketed bullet, which would incline me toward using lead data for plated.

Also, virtually all jacketed 9mm bullets are .355 whereas plated bullets might be .355 or might be .356.  If I were using .356 plated, I would definitely default to lead bullet data.

And that said, I stopped shooting plated bullets completely quite some time ago, so don't listen to me.  I don't know jack.  ;)

With that said by using the data for lead bullets I should be right in the ball park at starting my ladder at 3.8 and going up from there. Thanks for the info IDescribe

I've got my eye out and would definitely like to try Sport Pistol if I come across it at any of my local stores.

That said, the thing that has impressed me the most out of this entire thread was the PRISTINE condition of Wobbly's press.  Mine has never been that clean, even when it was new!  Do you eat off that thing?!?   ;)

Those are my results :

The bullets were 124gr Xtreme RN
OAL is 1.120"
Using S&B primers - SP
The gun was the Canik P120
10 rounds per loads
Mixed brass
Temperature was 52 degrees.

 Powder Load     AVG fps       AVG PF                 

      3.9gr                 1007          124         

      4.0gr                 1028          127
   
      4.1gr                 1039          128

      4.2gr                 1067          132

      4.3gr                 1078          133

      4.4gr                 1086          134

      4.5gr                 1101          136



Bottom line:

The powder measures very well in my Lee dispenser.
The Sport Pistol measure similarly to Titegroup with comparable results.
This powder seams to burn cleaner, with less residue than TG.
Loads at 4.3gr and above have an stronger recoil kick with an 11lb RSA. Stronger spring might be needed.
Accuracy was "best" at 4.1gr and bellow, but acceptable at 4.2gr and above.
Again, it is overall very comparable to Titegroup.

My future load for the Canik P120 and the Sport Pistol powder will be set at 4.1gr 124gr RN and OAL 1.12

I just picked up 2 pounds of it at Bruno's today! My first time there. Just learned about that place. Seems to be popular for a little hole in the wall spot. Good prices, I'll be back for sure!

I finally bought my self a chrono and was able to get the range today for some testing. I tested Sport Pistol along with my previous Tite Group loads. I used mixed range brass, CCI SP primers, and Precision Delta 124gr JHP @ OAL of 1.095 +/- .002 shot outta my SP-01.

All data 9mm

Sport Pistol at 4.0gr ( 5 rounds )

AVG 1078
StdDev 8.46
Min 1067
Max 1088
Spread 21

Sport Pistol at 4.1gr ( 5 rounds )

AVG 1093
StdDev 14.95
Min 1079
Max 1117
Spread 38

Tite Group at 3.9gr ( 5 rounds )

AVG 1103.2
StdDev 11.95
Min 1086
Max 1115
Spread 29

Tite Group at 4.0gr ( 5 rounds )

AVG 1109
StdDev 14.94
Min 1092
Max 1129
Spread 37

Thought it was interesting there was wasn't much difference between the two TG loads. I am thinking I can drop the SP down to 3.8. I will make a 5 round at batch at 3.7, 3.8 and 3.9 to see what I get.

Interesting that your 124 PD JHP @ 1.095" (Same OAL I use with the same bullets) with 4.0 grs of SP gives 133.6 PF.
Mine with 4.1 grs of Vit n320 give about 132+ PF. --- my comp. load.

My testing of strings of different lengths suggests that there is a significant difference in average velocity of strings of 5 rounds vs 10 rounds, but not much difference between 10 rounds and 20 rounds:  I run 10 round ladders as a result.  Food for thought.  :)

to get a better sample average, 5 is not telling the whole story sometimes, yet as a quickie it gets you pointed in the right direction

I start with 6 round groups to get me in the ballpark. Then go back and re-visit with 10+ round groups when I know a little more.

I will make 10 round batches ranging from 3.7 thru 4.1 for next week. If I am gonna do it I prefer to get as much data as possible and do it right. I am very green at testing rounds and developing loads, would elevation affect the velocity of the same load specifications? I am testing these rounds in Denver area.

Elevation, humidity, temperature, brand of brass, primers, distance, bullet, type of chrono, gun, number of cups of coffee while loading, and 100 other variables all figure into the final figures. All you can do is be as careful as you can and report as many of these as you can think of.
