Home Forums Hunting & Shooting AR and Tactical Rifles 24HC Black Rifle Challenge Thread

It's possible that it may get better as I continue to shoot it but I started out with 80 rounds of FGMM then I cleaned all the carbon and most of the copper out and shot a modified Final Finish regimen like I do with all factory barrels. I'm not sure how much good it did on this nitrided barrel. After that I attempted a load workup with Hornady 178gn OTM before moving on to the Bergers. Right now I'm at 222 rounds. I have 28 rounds to collect drop data with before the match next weekend and it'll be an 80 to 100 round match but he has not released the COF. I guess the next time I shoot this we'll see if a little more shooting caused it to improve.

I personally think group one was position change because I maintained it after I pushed the first shot out and the next 4 were right with it. I realigned after I did my reload and POI dropped back to POA. The single round out could be me or the brass. I could feel inconsistent neck tension when seating. The 100 I loaded for the match are on once fired brass and I have 1000 more pieces of once fired that is annealed and prepped so I may shoot this again with those also to see if there is a difference.

I have a fairly high end nitrided barrel I installed recently as well, but it doesn't have many rounds down it either...................cleans up pretty well but I polished & cleaned it thoroughly before ever firing it. I've only shot it with a 6x scope & it's been just a hair over MOA; I'll eventually put a scope with more mag on it as well & see what happens as it's shot more.

I think the jury is still out on how nitrided barrels either do or don't change over time.

But I can say that Compass Lake Engineering, who are about as reputable as it gets in the field, & who install both Bartlein & Kreiger barrels, told me that they do not nitride any barrels because that prevents them from ever fully "breaking-in".

FWIW

those are nice rifles and nice shooting! I like that Knight.

I've had a few nitrided barrels and don't particularly love them. One of my buddies was having Lilja barrels nitrided when he shot 6.5-284 in NRA Long Range and said it was a waste of time and money. When I ordered this gun I asked about getting a non-nitrided barrel because my .223 Wylde from him is plain stainless. He didn't have any non-nitrided so I ran with it. If and when I wear this one out the next one will just be regular stainless and when I put together an upper in 6.5mm for this one it won't be nitrided either.

Interesting about the nitrided barrels. Good luck at your match!!!! You said you noticed differences in neck tension while seating bullets, that can have an adverse affect on accuracy. Hopefully those cases you annealed, turn in better results. I need to go shooting!!!!!!!!!!!

a lot of bolt bounce there....

Thanks, Mike.

It was windy that day, so probably a little room for improvement, not sure how much though; I've not been shooting enough lately, as Kenetic Perf says, to be as good as I can be or have been. When I was shooting pistols competitively, I was going through around 500 rounds a week & your trigger finger can definitely tell the difference.

I've had that KAC gun for a while & I do like it a lot too for what it's intended for, but actually, I like the 18" WOA barreled rifle better mainly because of the handguard that is on it.

Here's an entry for those Stag shooters. Didn't want to let you guys down.... ... Went to the range today with some new loads to try. Finally getting around to testing some of this AR Comp powder. I like it! Seems to meter just fine. Probably a tad better than RL15 and every bit as accurate in my Stag 6HL. I wanted to shoot before it got to 100 today!!!



Ran out of the better load, so the second group was not as good as the first, since I had to throw in a few from a different charge wt. I'll load up more of the first load and shoot again. Looks pretty promising... The stag is not picky at all....

Rifle on the bags and the range in this pic. 101 yards to the target:


I'm pretty happy, the new nickel boron Black Rain Ordnance BCG is working like a champ....

Oops, almost left out the picture with the caliper:

He said he was going to update the standing a few weeks ago. Don't know if he got around to doing it though...

Doesn't count, 101 yards to the target. DQ!

Nice shooting!

Ah dang it, I knew I screwed up!!!!

Nice shootin. That'll do!

Thanks buddy! I'm liking these AR's...

I apologize for not keeping up with the rankings. This is every legitimate entry I found since page 15 when I last updated the scoreboard. Moving forward I will try to keep it more up to date.

Photobucket crapped out on me and lost my target which knocked me out of the top 10 but I will get back up there.

Thanks for all your work on this wareagle. Looks like more guys need to try their hand in the iron sight division..... My buddy has a cool old busmaster hb rifle that would work great for that. I may snag it and give it a go, but no promises there...

Irons are wide open, there isn't a good score or group posted there yet.

Really? There is an excellent score posted for iron sights... yours! I have to say that I am impressed by your shooting ability, and your modesty. Thanks for hanging around, and sharing your knowledge.

The best iron sight group that I have been able to pull off is a 3.3MOA, 20 round group at 50 yds. I shot it with a 20inch Colt upper that my Dad left to me. I'll never modify that one.

Thanks, but my shooting was sloppy and others should be able to shoot better than me. Its what happens when you go from a lot of rounds a year to almost none...

IMHO.

I"d not get rid of anything my dad left me either!

You did great!!! You are too modest...

I'd say 1.351 moa for open sights is darn good shooting and would be hard to beat. When the weather cools off a bit I just might have to pull out the 20" Colt and give it a try.

I don't think your place will be in any danger.
