Berm picking seems to be getting more popular.
This video mentions some of what's already been said here: boat ballasts, WWs, roofing lead, but it also shows some sort of lead containers used to transport radioactive materials for the medical industry...
Those primers are looking awfully rounded in the picture he posted. My bet would be on using too weak of a loading. CCI SPP have a harder primer cup than FED,REM, and WIN. So take that into consideration and combine it with used brass. The pressure needs to be high enough to expand the primer...
Not sure about 9x19mm, but with 9x23mm HS-6 works well with 90gr & 115gr, where as Longshot works well with 158gr.
Have you tried Longshot with a 147gr bullet?
What kind of drop were you getting with those loadings?
124gr@2400fps 7.62x39mm has a drop of about two feet at 300m, I can't imagine that a 9x19mm would be less than that in most cases.
These are examples, not loading information:
Cartridge : .38 Super Auto +P (SAAMI)
Bullet : .355, 124, Hornady HP/XTP 35571
Useable Case Capaci: 12.942 grain H2O = 0.840 cm³
Cartridge O.A.L. L6: 1.280 inch = 32.51 mm
Barrel Length : 5.0 inch = 127.0 mm

Does not look to be in stock, if you look at the url, the "b1000.htm" is the quantity so "b0500" is for 500 "b1000" for 1000. I tried the b1000 on what I bought and it seemed to be in stock but just went with 2x500 as to not screw...
Are you using this in a 10mm barrel or a throated 40S&W? What weights of bullets can you use 180gr and 165gr? Seems like a good idea considering you don't have to mess with the more expensive brass or large pistol primers.

I don't have the actual work up data anymore, but it was using Longshot and HS-6 with 100gr .355 projectile in a 38 Super with 4.5" barrel. The loadings seemed quite linear in velocity gain with .2gr increments. At one point the Longshot stopped gaining velocity, i.e. plateaued, HS-6 did not and...
Why is that? I've had powders that would theoretically give the best velocity, but ended up plateauing due to barrel length. A slightly faster powder actually did better. BE is fast compared to Unique, but I can usually go faster than that with even slower powders like HS-6 and Longshot, but...
Picked up a carhartt belt about six years ago and it works well although the design of the buckle could be better. The actual belt portion is a leather inner layer and nylon outer layer, works really well.
This website may have some useful information related to what you're looking for. It doesn't provide proportions, but does list the chemicals used in the powder (check the drop down menu for the powder you're looking for, they have a bunch).
I've been trying to use the heaviest bullet available when shooting plated, in this case the .357 158gr Xtreme PFP. They seem to have added a .356 165gr PRN so I'll be ordering that on my next order. Also have used the .357 158gr Hornady XTP and HSM PHP, with similar performance(1100-1200fps)...
A few months ago I used up a red/yellow cardboard can of Unique from the early 80's/late 70's. Poured some out on a piece of printer paper and it looked fine, smelled ok too. Didn't notice anything off about it. If the powder you want to buy is like that, it's probably fine.
1: I would figure out what loading you want to use and try both. You will probably find that one will cause less spread in the velocity than the other. I have used SP, SM, and SR primers in my loadings and usually one will work better than the others, but you'll have to try and see.

That might have more to do with the velocity than the bullet. A heavier, slower bullet requires a more aggressive rifling twist rate to stabilize if you don't up the velocity. The heavy plate might work better in your polygonal barrel, but I don't really have much experience with that type of...
My normal practice loading is a Montana Gold 165gr JHP @ ~1050fps out of a M&P40c. They seem to be accurate enough that I hit what I'm trying to shoot.
