was there a difference in accuracy between 3.6 and 3.7?

It finally arrived...



This stuff is a flattened ball powder with a graphite coating. It looks a lot like W231, but the flecks are smaller and vary somewhat in size. It's like they use 3 different flake making machines to make the product. Anyway, this photo looks different to me than the one at the beginning of this thread. Here's a photo of the product received today in the Alliant bottle cap...





? It does meter very good. I need more test time to say more than that.

? Flake size is such that it does not "leak" from a standard Dillon powder measure.

? The load data shows it being as frugal to use as W231/HP-38. Loads for typical 124gr JHP seem to be in the 4.0 to 4.1gr arena.

? Packaging is in the standard Alliant cylindrical plastic bottle. Weight is 1 lb. Bottle is approximately 3/4 full when new, meaning this is a powder of average density.

? Case fill is excellent in 9x19mm. Shown below is 4.2gr in a Luger case. Just enough to prevent a double charge, but not enough to slosh out in a merry-go-round progressive...



I've got my incremental loads worked up with Precision Delta 124gr JHP seated to 1.100", 3.8gr to 4.4gr in 0.1gr increments.



I'll report back on Sunday with results.

 ;)

Good info all so far.
Easy to meter.
Good load spread.
Previous chrono results looked well-behaved.  Looking forward to Wobbly's results to compare with the 124 JHP PDs.
......cleanliness,/spent case codition
......muzzle flash
......accuracy:.(not optimal when chronoing but a sense of potential works)
......heat?

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?

Based on what Berry's says on the page for that bullet:
https://www.berrysmfg.com/item/bp-9mm-356-124gr-hbrn-tp
Quote
"The bullet profile is longer but the weight remains the same and you can load these bullets using any published load data for a jacketed bullet as long as it is the same weight bullet." 

Then referring to the Alliant load data here:
http://www.alliantpowder.com/reloaders/powderlist.aspx?type=1&powderid=42&cartridge=23

124 gr FMJ
Min OAL: 1.12
Max Charge Weight: 4.5 gr
Reduce by 10% and start from there. 90% of 4.5 gr is 4.05 gr, so your starting charge appears that it would be lower and a safe starting point.

*****BUT......
Berry's has some confusing language on their site about using FMJ or lead data. The reloading pros on here might give you additional guidance...

******* PS
Alliant lists load data for the Speer 124 gr RN TMJ, which is seen here:
https://www.speer-ammo.com/bullets/handgun-bullets/tmj-handgun-plinking-bullets/355/355-124-tmj-bullet

That load data is different and Ive read that the Speer TMJ is a thicker plating than what Berry's normally uses. That is just what I've read, and I haven't called the manufacturers. That being said you can give that load a try. It is a longer OAL... That is what I will definitely defer to the pros on here to see what they say.

The HBRN-TP bullets are "thick plated" and Berry Bullets rated to 1500FPS.  I use these for my "Practice Self Defense Loads" at around 1200 fps' same as the more expensive Speer 124 gr Gold Dots in my EDC.

I've shot many thousands of the BRY 124 HBRN-TP.  The only difference in load results I've seen is that the "Hollow Base" provides more air volume below the bullet base than than the bullet length and oal indicates.  Over a chrono it will be slightly slower than a flat base bullet of the same weight and type at the same "seating depth".
Hope this makes sense and helps.

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.

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?!?   ;)
