Interesting Powder for 9mm Luger

Hi Sieger,

I never thought of this, and assumed high pressure was responsible for breach block slap and didn't give it a lot of thought, but after thinking about this a bit I totally agree. Thanks for the wake-up call.

I am trying to get a handle on these Lugers as far as reloading still. I wish it was as simple as trying one of your favorite loads, but I have limited powders available; recently all I have been able to buy is Titegroup which is pretty quick-burning. I have had decent functioning at starting and near starting loads, so I really don't believe pressure is an issue. I have seen a little bit of breach block slap though which I don't like.

Is it the burn rate that causes BBS, or is it some other powder characteristic?

I just noticed after typing this that Blue Dot is fairly slow, so maybe it is something else that causes this other than burn rate?

There has been some of the VihtaVuori powder around locally but I have avoided it as 1) It's quite expensive 2) I don't have any history with it. But ... maybe I should try some VV N330 if I can find some locally - it's right by Power Pistol in burn rate. Thoughts?
