Rosco Barrels any good?
My 20" mil-spec HBAR is trash.
Are Rosco barrels any good? I want to lighten up my rifle some and found one of their medium contour SS barrels here.

It's a beautiful day in the neighborhood, a beautiful day for a neighbor, would you be mine, could you be mine?

If I was a spammer, wouldn't I be singing their praise instead of asking about their quality?
Also, I doubt primary arms needs folks to spam gun forums to drive traffic to their site
Another brand that I know first hand is great quality is Criterian.

2nd .224" and one .284"
"The Un-Tactical"
Tried 4 different brands/types of ammo. Excluding the flier on the first group, the groups got worse the more I shot, I suspect the copper fouling building up is a prime candidate as to why.
Fiocchi 50gr A-max used to get it on paper. first 3 through one hole at 50 yards shots 4 and 5 were 1/4" high and 1/4" low respectively, opening it to just over 1 MOA
Same ammo @ 100 = 2.5" group. A first round flier after scope adjustment opened it up from a 1"
IMI Mk 262 Close (77gr Sierra MK) ~1.25"
S&B 77gr MHP = 2"
Winchester Silvertip 64gr Defense Tip= ~2.5"
The Silvertip looks a LOT like their "Deer Season" ammo, with a silver plated jacket. Their QC seems questionable. This is 3 of the first 5 I removed from the box. I'm not sure if it's different cannelure placement, or the case length/COAL varies that much? Doesn't give me a warm fuzzy feeling about trusting my life too it though
9/10 in a 1.25" group and the called flyer opening it up to 2.35"
The forum software rotated this pic 90°
In cleaning, there was NOT nearly as much copper after this 15 rounds of the IMI 77gr

That's 5 shots of the same lot of IMI Razor Core 77gr (aka mk 262 mod 1 clone)
Also had the heavy barreled precision upper that normally lives on that lower, and couldn't match it with a barrel that cost 3x what this one did
