I bought it from Kufford here, in the syn stocks he had acceptable accuracy after he got it back from H&R for a chamber problem, too little headspace IIRC, but barely as I recollect, 2"+. I never shot it that way, put a camo lam set on it, polished the bore and chamber and shot 150gr Fusion ammo with it, accuracy was just over 1" IIRC, velocity I remember well at just over 3000fps, The only syn stock set that I've had good luck with out of the box is on my .30-30, others I've had to play with hole position and O-rings to get to shoot good.
I don't know if y'all notices, but it also has polished steel spacer, trigger guard, hammer, trigger and barrel release, no black parts.
I don't think an SS .45-70 barrel is available, but ya never know, they supposedly never made 24" bull barreled Hornets either, but Shaner has one!!
Don't tell the ATF, spanky!!
Thx,
Tim
