River rat23
WKR
Putting together my first sbr in a week or so. Ar15 platform with 11.5" 1-7 proof barrel in 223 wylde. I have tons of bullet & powder options on hand. Anyone got a similar setup that they're loading for currently? Just looking for a jumping off point before I start a load ladder on my own. Will be shot almost entirely suppressed. Thanks in advance. Cheers
