It's been 20+ years since I ran my RL550B...and I'm slowly working back into shooting with any regularity. With varied interests, and all the usual life oriented time complications, I'm probably coming into this backwards, but at any rate...
Recently finished getting new rifle set up, .300 BLK upper, 9" Faxon barrel, 1 in 8 twist, Obsidian45 suppressor, Leupold RDS optic. When I started project, I intended to assemble myself, but eventually realized smart move would be to enlist help from experienced gunsmith for a dependable suppressed "go-to" home defense oriented upper. So, I researched and chose parts myself, but had it assembled and initial setup with suppressor done for me. I followed up with short range sight-in and tested several factory bullet weights looking to see what the rifle likes.
Setup and sight-in was done with Hornady Black 208 gr AMAX, and I followed that with some Winchester 200 gr, Underwood 220 gr, and a box of Hornady 190 gr SUB-X...it liked the Hornady 190 SUB-X's best by far. I'll probably always have factory ammo loaded for a personal/home defense scenario...but I'll want to replicate the factory round as best I can for practice/playtime and this seems like a good starting point.
I've got a bunch of new starline brass and ordered a box of the Hornady 190gr SUB-X bullets...but powder selection seems wayyyy more complicated these days, especially since I'll be trying to load subsonic. I'm wondering if anyone has any thoughts/experience with replication of this Hornady subsonic load??? Or similar powder/bullet options??
