I've gotten decent groups but I've only shot out to 100 yards which doesn't even begin to show it's potential. On a side note it's not the chrome lining but how it's applied which affects accuracy.

Did you shoot factory or tried to tweak a handload to the rifle? I've got my old superlight barrel to do 1.5MOA @ 100yards with 55gr V-max 23.5 H335 2.200 OAL and was happily surprised from the accuracy obtained from a pencil barrel. Will take my new upper to the range when they open up the range again. |

It's a good barrel TXL |

May I trouble you for the OAL of your loads? Will my velocity increase with .223 in a 5.56 chamber if I load my rounds to a maximum 2.260 (fits in mags) over my regular 2.200? Thanks again for your input, looking forward to testing it out tomorrow (unfortunently indoor 50yards) Chris |

I have been quite happy with the accuracy of my 16" Bushy H Bar. This particular barrel is quite content with everything I put through it. Premium factory ammo or remanufactured, all obtain 3/4 MOA.

20" V-Match (post-ban, bare muzzle), 16x scope, JP trigger, bipod, 100yds will do 1/2" 5-shot groups with Hornady 55gr V-Max. About 5/8" to 3/4" with USA 45gr JHP. More like 1-1.25" with most ammo, up to about 1.75" with M193 and 3-4" with Wolf.

I have a "24 inch V-match chrome lined 1/9 bushy upper and I have gotten very good groups with it at 100 yards (that is the longest distance I have been able to shoot at) less than 1 MOA. I have used Black hills 69 & 75 grain and they have both performed very well giving me very tight groups. Also WWB 55 grain gave me good results at 100 yards but it was more like 1 1/2 to 2 moa. I do not really know how many rounds you can put through it before the groups open up because my eyes usually fatigue before the barrell gets hot (I like using iron sights and have no scope yet).

Got a .6" 5 shot group @ 50 yards indoors today with a crappy rest with 55gr V-max molys.
How many rounds does it take to break in the chrome lining? C |

87 rounds. And I've shot 1.75 MOA with Irons with My Bushy HBAR. Pretty good 100 yard group for my so/so eye sight! |

I have a 16" HBAR Bushy that shot a 7/8" group at 200 yards with Federal Premium 55gr. Nosler Ballistic Tips. Good enough for me.

Moly bullets in a chrome lined barrel are a waste of money.

.75" 5-shot groups at 100 yards with my 18" chrome hbar. That's with handloads (53gr. Hornady match HPBT's in front of Varget).

The molys shot better than the regular V-max so I guess they are. |
