A while back I bought a 20 inch Hbar in .223 Wylde for a SPR build. Ended up finally getting around to build it (after over a year), except the barrel is shooting absolutely horrible groups. After some experimenting, it was determined the barrel is garbage. Is there anything that can be done with it besides keeping it next to my work bench as a club (joking)? I read somewhere it was possible to recut the barrel as a larger caliber. Is this true, and is it cost effective to do something like this?

whats wrong with the barrel ? is it as simple as re crowning it ? 

Build a .22lr upper ?

I'm curious what could be off about the barrel too.  Do you know the maker?  that sucks that a Hbar in 223 wylde is not shooting to your expectations 

if it is trashed, maybe you could consider getting the barrel chopped down and re-profiled to another desired length.  14.5-16" for CQB type distance?  maybe it's still usable in a different config.  could be a fun project

You could have it bored out, re-crowned, re-plated, and re-stress relieved. But you'd be into it for more than a new barrel would cost.

Does it already have a brake on it? Or is it non threaded? Im looking for a trashed barrel for some destructive testing.

I don't know the maker, I don't even remember where I bought it. I believe I bought it the last time I was at Oak's from some random table. Regardless, it's a 20" fluted Hbar in .223 Wylde, target crowned that shoots groups from a lead sled of 2-3 FEET at 100 yards. I looked through the barrel and don't see any knicks, gouges, burrs, or dings, but at this point, I'm just frustrated and done with it. Was just curious what I could do with it.

god damn that's terrible!

Hang it up over your work bench as a reminder of what not to do in the future.

Spring's coming, tomato stake for the garden

Turn it into a cane.

When you look through the barrel can you see any spiral shaped grooves? With "groups" that big it may be a smooth bore.

Do you know the twist rate?  What bullets are you using?

 

Have you also checked your optics or your sights are tight?  I have done that once where the optic was moving all over the place cause I forgot to torque it down to spec.

I see the lands and grooves, they're there. If I remember when I get home, I'll post a pic.

Kinda hard to see

it's a 1x8, and I tried everything from PMC X-tac to Rem .223 to green tips. I thought the scope was the issue initially, but I switched both the mount (now a Burris PEPR) and the scope (now a Nikon Buckmaster 2), lapped the mount rings and blue locktite-d everything down, still getting garbage groups. I literally just put a new barrel on it this morning (a 18" stainless 1x8 twist match .223 wylde barrel that is guaranteed to shoot sub 1 moa, or my money back) and plan to go shoot it Sat morning before work to test it. Being that the barrel was essentially the last thing to try replacing, we shall see how it goes.

Was it new ? Contact the manufacturer

Tried iron sights to make sure its not either scope issues?

I think we have found the problem...

Scrap it for $.0573?

...that shoots groups from a lead sled of 2-3 FEET at 100 yards...

Wait, you're telling me that isn't good? My range neighbors always seem so impressed I can keep my targets clean (and reusable!) while showing off my accuracy on their targets. I'm told like all the time that I must be a sniper or mall ninja (don't get what a ninja has to do with guns, dumbasses don't know ninjas use swords?), but I'm always glad to show off my skills.

Uhh, do I WANT to know what a clam cannon is??
