I have bought (4) Ruger #1s, all of them thinking I would rebarrel them.
All were too accurate to rebarrel.
I got this #1V 223 made in 1999 used of an on line auction in 2007 for $500.
I was full of Copper fouling.
I cleaned it out and sighted it in with mixed brass handloads 15 gr Blue Dot 35 gr Vmax.
It shot real well at 100 yards.
I give up. None can be rebarreled. They all shoot too well.
