We need some testing done with Lead !!
EquipmentBullets: Acme 124gr LRN coated
Brass: Federal Cartridge (F.C.)
Powder: Alliant BE-86 (5.7gr max)
Max Vel: 1179 fps
Primer: Federal Small Pistol Match #GM100M
OAL: 1.120"
Pistol: SP-01 Tac
8 rounds each, slow fired
68F, clear and bright sun

*** Shots Not Taken ***Notes- Testing suspended at 5.6 because there were velocities at 1190 with 5.6gr
-
* Only 3 shots registered skewing the results. They are probably closer to 1140 fps with a higher SD. 5.3gr is
not a magic node.
- Used load data from Alliant, which lists only a Max Load
- Shots were smokier than expected considering thick coating and cooler powder
- Overall accuracy was good
- All shots operated my SP-01 slide with 14# recoil spring. No FTF noted.
- Probably should test at lower loads. Testing down to ~4.7 for plinking needs.
- As tested, this is not a good plinking powder for Lead due to excessive powder requirements and higher than needed velocities.
Hope this helps.
Examples....Same clean shooting BE-86, even with lead....
