It looks like I'll be stoking my 4" GP100 with full-house .357 magnum cartridges to meet a IDPA Match Director's challenge for June, which means I'll be concurrently using the gun for duty/carry to a significant extent.
I'll be using Sellier & Bellot 158 gr .357 for the match to make the requisite power floor; since I'm zeroed for 158 gr, what cartridges does the p-f community recommend?
I have Hornady Custom 158 gr XTP on hand, which is my standard .357 hunting cartridge; how would it stack up concurrently as a defensive round?
Thoughts and recommendations appreciated-I perused the older threads using the Search function, but didn't find all that much, particularly recently, so I thought I'd initiate this thread.
Best, Jon
