Re: .380acp/9mmK carry ammo
For interest, here is my data from my own spreadsheets. For comparison, the S&B RN Factory ammo was also tested.
The Rangers were the only other premium brand I had for comparisons. They worked like a charm in the G42.

Oom Piet, what powder charges did you use for the 100gr Frontier and 92gr Hornady XTP?

Re: .380acp/9mmK carry ammo
Hi Ds :)
For the 100gr Frontier: Winchester SSP, 24.9mm, S121, 3.8 t 7
For the 90gr XTP: Winchester SSP, 24.1mm, S121, 3.8 t 7
Explanation: "Track" (t) and "Push" (p) are what I use in my records instead of double digits for the powder charges. So you can, on a volumetric machine, never get a precise constant weight of powder (because powder hoppers measure in volume, not weight). It will always vary a little. So you can set the machine up for 3.8, but it will always vary. So you can set the machine up to throw 3.8 and vary downwards (track, for example "3.8 t 7") or vary upwards (push, for example 3.8 p 9), and you can note of the tendency if you measure it over several runs. From there it is to the crony. I find this method less insane and frustrating than trying to get constant weights measurement out of a constant volume measurement :) So, "3.8 t 7" means it is set up to mostly throw 3.8 grains, but if it varies, it tends to vary downwards (to 3.7), more often than it does upwards.
Hope this makes sense :)

Re: .380acp/9mmK carry ammo
I found S&B JHP runs 100% in my 32ACP PPK. This olde pistol is also known to be sensitive. The S&B is loaded fairly hot and is heavier than most other brands. Can't see why the 380ACP JHPs shouldnt work for u. And it will be cheaper than American imports.
