I have a Remington PSS 223 caliber in like new condition, 26" hvy bull bbl. this rifle is a tack driver with 3/8" groups at 100 yds from some old reloads of mine I had since 1998. 70 Gr Speer semi spitzer's behind some W748. Haven't experimented with any 50 or 55 grainers or any other powder but imagine it could be tightened even more.
