[Last Edit: SuperJlarge]
The purpose of this thread will be to document the precision and reproducibility of various barrels. While I have had good luck with several of the barrels currently at my disposal, I’m not biased to a particular brand/manufacturer. At the end of the day, I just want a barrel/rifle that will shoot. Doesn’t matter to me whose roll mark is on the tube. Cost effectiveness is always a plus though, for me and likely many of you reading this thread, so I’ll try to include street prices along with the results.
Testing: Testing will be at 100yds minimum, using a bipod and rear bag. Note: this isn’t specifically for the MOA challenge, but the rear bags will likely conform to the rules. I don’t own any V style benchrest bags. Ammunition:Tests will be conducted using factory match ammo as well as handloads. If there are specific match loads or reload recipes that you’d like to see tested, feel free to leave a request and I’ll see what I can do, provided that the request appears safe. Optics: All optics used for testing will be suitable for getting the most out of the barrels. Vortex, NF with a minimum top end of 20x. Triggers: All triggers used will be match/target 2 stage triggers, with a 3.5lb or less pull. Sorry HP guys... Groups: All groups will be a minimum of 5 shots (unless load development), with a minimum of 3 consecutive groups. I’ll strive for 5 groups, but based on the potential number of barrels/ammo combinations, the ammo costs could prohibit such extensive testing. Current barrels: LaRue Stealth, 5.56, 16”, 1:8 (in house produced, non LW) LaRue Stealth, 224 Valkyrie, 1:7 Rainier Arms Ultramatch, 223 Wylde 18”, intermediate gas, 1:8 Shilen blank Rainier Arms Ultramatch, 223 Wylde 18”, intermediate gas, 1:8 Shilen blank Daniel Defense, chrome lined, Govt profile, 1:7 Rainier Arms, Match, 223 Wylde, 16”, 1:8 Rock River Arms, 223 Wylde, 16”, 1:8 (std. barrel, not varmint or PP) Ballistic Advantage, 6.5 Grendel, SPR, 18”, 1:8 Ballistic Advantage, 6.5 Creedmoor, 22” (non-fluted), 1:8 X-Caliber, 6.5 Grendel, 18”, 1:8 Falkor Defense/Dracos, 6.5 Creedmoor, 22”, 1:8 Falkor Defense/Dracos, 6 Creedmoor, 22”, 1:8 Krieger 223wylde, 20”, 1:7.7 BCA 223wylde, Nitride fluted 18” mid length 1:7t Rainier Match, 18” RLG, 1:8 (new version, Black Friday sale) Rainier Rock Creek, 1:8twist 18” intermediate gas (.936 gb) Rainier Arms Ultramatch 24” 1:7.5t 224Valkyrie Rainier Arms Ultramatch Fluted 24” 1:7.5t 224Valkyrie Proof 18” +1 gas 6mm ARC The Falkor builds have been placed on the back burner for the time being. They are a higher price point and aren’t the typical first choice for most shooters. They also have predator optics on them currently and it’s a pain to readjust/remount. Other barrels: If there are other barrels that you would like to see tested, please let me know. Obviously I can’t just purchase barrels for the sake of this thread, but there may be some that I was already interested in and you could help to push me to place an order. Also, if you have a barrel or upper you’d like tested, reach out to me and we may be able to work something out. If anyone has any questions or suggestions to the format of the testing, please feel free to send me an IM. I’d like to keep the thread mostly for ammo/ barrel suggestions and discussion of the results. |

How many rounds per barrel per test? Statistical analysis?
5 round groups should be ok, but a final compilation of all the groups on 1 target using software is always a great summary. |

There’s also more variability of the system since this isn’t “controlled” or mechanical testing, but I’ll see what I can do. I have a few statistical analysis programs at my disposal, but may not have the time to perform an in depth analysis. All of the information will be in this thread, so feel free to perform it yourself. I’ll try to be mindful and not make any scope adjustments between strings or change muzzle devices.

It will be interesting for sure. When researching the barrels a bit last night a stumbled upon a thread where a PA representative indicated you get what you pay for with the BCA barrels. Maybe I can get it to shoot, but if it isn’t showing any promise, I won’t spend a lot of time on it. The recommendation for a budget barrel from him was for Ballistic Advantage.

Man that larue barrel did not like the Hornady stuff did it?
I almost went with BA for my build but couldnt find the barrel I wanted in stock ended up with a Green Mountain barrel that had the same exact specs for less. Its a shooter for sure sub moa for $200 bucks hard to beat |

Honestly, probably just luck that it did that well. May test it further, just because I have a few boxes, but it’s probably just decent plinking ammo. https://i.imgur.com/R7u0Ty7.jpg View Quote |

Had to deal with a water leak at my girlfriends house today, but the FGMM 77’s and ADI 69’s showed up. Hoping to get some range time in tomorrow.

SuperJ, I see you like those JP Rapid Configuration handguards. Out of all of the AR's I've shot and own, I think that particular JP Rapid Configuration handguard is the best (I have JP's other handguard, the "Signature" handguard, and it is okay, but nothing like the RC). It also helps that it is aesthetically pleasing as well.
Thank you for doing all of this work. I recently acquired a LaRue PredatOBR (at an absolutely smoking deal). I am going to put it up against my JP-15 and see which rifle can do what, given the same ammo, as well as trying to match other variables. I am a huge proponent of JP Enterprises when it comes to precision gas guns; I always recommend them for the simple fact that they work really well, and are hyper accurate. Anyhow, I figured at this point, I'd give the LaRue a shot. I recognize that this is a sample size of one from each manufacturer, but it's still a cool thing to be able to compare. The way I want to do it is going to make it rather time consuming, but at the same time, it should be a good time. On a side note, I've read tons of posts and reviews and what not on the LaRue MBT. With regards to AR's, I really like my Geisseles and JP's single stage trigger, but that MBT surprised the shit out of me. Granted, I have only dry fired it, but to be honest, it felt damn good. I wish I could run it in my duty rifle, but I digress... Good luck with the testing. Are you running different optics for these tests, or sticking with the same optic (for my edification, only). Thanks again man. Be safe. |

I won’t be selling my Geiselle NM’s to replace them with MBT’s, but they are an affordable alternative to the SSA’s. Optics will be different among most of the rifles. The 4 that I hope to test this weekend will have a mix of ATACR, Razor, PST Gen2 and RzR AMG for glass. |

Initial run with the Rainier Ultramatch, LaRue Stealth running ADI 69 and FGMM 77 is posted (Post #3).
Also ran some load development with the Ballistic Advantage 6.5 creedmoor. |

The DD is a 16" carbine?
From it, I'd like to see the performance of- Factory ammo: Hornady 75gr Match Handloads: 75/77gr BTHP over 24 - 24.5gr Varget. 50/53gr VMAX over 25 - 25.5gr Varget. The 53g VMAX is slick; might need to jump another 0.020" at 2.23-2.24" OAL if the ogive allows. |

Fantastic thread. Thank you for undertaking this and sharing it with us. I look forward to more posts.
For groups at 100 yards in .223 various chamberings (.223, 5.56 NATO, .223 Wylde, etc) have you considered lighter weight match bullets? Berger's .224" Flat Base Target bullet comes to mind. It is giving me consistent sub 1/2 MOA at 100 yards from a Lilja 16" 1:8 Wylde chambered Recce profile barrel. The limiting factor is me. No telling what they are capable of from a true benchrest rifle. Match grade flat base bullets, especially in the 52-53 grain weight often shoot a bit tighter at 100 yards. Bullets like the various 77 grain OTM choices, are greatly superior at longer distances due to higher BC, but may need more than 100 yards to settle down. Give the 52 FB Berger Target bullets a try. They are spendy. Sierra's 52 BT is close at 100, less expensive, but not quite as accurate for me. Powder for the 52 grain bullets is H4895 or L-32. H4895 has been more consistent, but is very coarse long grain extruded. I've been working with IMR 8208, but not getting the results I would expect so far. |

Pulled the 16” LaRue stealth barrel and will be shipping it to LT for them to look it over. It showed potential, but the shift has me thinking something may be slightly off.
The replacement barrel for that rifle will be an 18” BA 6.5 Grendel. I installed that barrel last night and picked up some Hornady Black 123 eld ammo today as well as some Black 75gr. Debating on testing the LaRue 224V. I’d like to see what it will do, but I’d also like a 22” +2 224V from a Bartlein, krieger or Rock creek blank. To sell or test....decisions. |

Very interesting thread.
Excellent Idea to have 1 shooter , with so many barrels. I hesitate to ask, but have you considered testing the Hornady 75gr Steel Match / Training round ? IMHO, it is a bargain 75gr round. ( Selfish reasons... my Krieger barrel loves it. ) I would volunteer to order some for you and your tests, and have it shipped to where you'd like . ( IM me if you are interested ) |
