300 AAC BLACKOUT (300BLK)
It is not a good choice for long-range hunting. If you would not shoot it with a scoped-30-30, then you would not want to shoot it with 300 AAC BLACKOUT. We are doing optimized bullets though - something in between the two in the video is the goal.
400 degree solder is 400 degrees F. It cannot hurt an action. I would not be too excited about using 1200 degree F silver braze on a custom action.
I ordered some and will try it out.
Nesika actions have 6 8-40 screws and two dowel pins.
Rem actions have 4 screws - either 6-48 or 8-40 (M24 and a few others).
Does blueing or phosphate have to be sanded off? I suppose so - I sand before I solder copper pipes.
Has anyone soldered a scope rail on using 400 degree 'aluminum solder paste?'
