Hi,
Well..there are a couple cosmetic flaws on these 2 as they were used for proofing out all the machining operations so they cannot ever get into the wild via a customer!!
Sincerely,
Theis
blems?
Maybe you can donate them to the club I’m affiliated with.
The PRPC.
Our mission at the Precision Rifle Poors Club is to support those who partied maybe a bit much and chased poon and kegs instead of doing our homework.
Theis,
Have you/are you finding/working solutions for running your cartridges at 80kpsi as far as barrel life is concerned? Are structured (tacom) or sleeved (Teludyne) style barrels in that orbit to reduce wear through greater heat mitigation? DO you have another method(s) with coatings melonite etc that you would care to share? I've read this whole thread over the last month and I may have missed that.
I understand that barrels are consumables but really good ones are tough to let go of when you get one.
Thanks in advance

Hi,
My new RRS tripod and ballhead arrived today from @Praeger and decided to check fit of our handguard....great!!!

Hi,
@ubettcha
You did not miss that information in the thread as it is still a work in progress..hence why the HP cartridges data has not been released.
We at Hoplite Arms are currently working with a ceramic lining company but are still in the thickness, consistency and methodology to ensure precision stages of our talks. Hoping to have more on that towards summer months.
Right now, since we are able to essentially use a faster burning powder than what would normally be used because we are not limited to a pressure threshold per say....we are able to shorten the burn rate aka time under heat of the ignition by having the fast burn of the powder which helps reduce the throat burnout.
We also are pretty much running strictly monolithics of a very small engraving area to help reduce the overall wear and tear of the barrel but as we all know....the throat heat is the enemy way more than engraving area of projectile.
I personally see no advantage of those barrel types since the heat generated from the powder ignition remains the same no matter how fast the heat dissipates from the barrel itself...IMO that is.

Theis

Hi,
Entire chassis...
7075 Aluminum center and 7075 18" handguard with PRS Gen3 buttstock and Ergo Grip.
Sincerely,
Theis
As heart breaking as it sounds, I’m sure Theis will make this sacrifice on the altar of ultimate user safety. You have to please the gods by sacrifices occasionally to keep on firing...?
Hi,
Ergo Grip #4014...just the chassis is cut to help make it more vertical.
Sincerely,
Theis
Similar to the Otis ceramic life liner or hopefully much improved? Just watching how this is coming together I'm sure your approach is well thought out with conclusive testing. Isn't the faster powders more prone to throat wear with the highest heat at their peak pressure earlier in the pulse over the longer pulse of a slow single based powder like H1000? I'm basing that on the reason the 6mm competition match over the 243 was due to the use of H1000 over 4350 without crunching powder. THis lengthened barrel life due to the cooler throat temps of H1000 in that instance.
Looking for the education not questioning your answer as IDK
Thanks in advance
Thanks. and great. I hope you will provide a service for that treatment for barrels once your up n running. I guinea pigged a decent 556 on that Otis method and it wasn't like the advertisement is all I can say.Hi,
@ubettcha
Sounds like a great test for a 3rd party testing entity to conduct
We utilize NTS for all of our independent testing requirements.
In regards to the ceramic barrel interior....significantly different than the Otis product.

Hi,
Just got the email from guys over at Birdsong......I pick up first batch of coated parts Friday evening!!

Random, but any idea how that coating would hold up to acidic atmosphere as per milstd810?
Hi,
Are you referring to Test Method 518.2 Acidic Atmosphere?
Mil Std 810 is a broad "guidance" platform.

I misspoke, its a ASTM G85 Appendix 4 SO2 salt fog corrosion test, 500 hour test. (sorry for the derail)
You can roughly approximate 100 hours of ASTM B117 as matching 1 day of ASTM G85. It’s nowhere near that simple, but that should get you in the ballpark for coated non-electrically-connected metallics.
CrN PVD is the most impressive coating I’ve ever seen at 1000h ASTM G85 and barely measurable mass loss on a bolt.

Kinda, yeah. I’ve worked professionally with IBC Coatings, who developed a hefty amount of the coatings and such we use in industry these days.

So just got back to shop from picking up parts from Birdsong...
Bolts and all inner pieces are black.

Can you do one in Georgia Bulldog Red? Or will it shoot good all season and then disappointment me when the game really counts?
The copperhead and the grey are my top choices right now with black bolt, black handguard, black barrel and black magpul buttstock.

Same. Was going to build a custom rifle but think I’m going to save for this instead
Hi,
That would be a no.
You do realize that a Sentinel stock alone is right over $1200?
We are not competing with RPR market......There are lots of decent rifles in that cost bracket for that intended market to pick from; We at Hoplite Arms will not be joining that market circle by DESIGN and PURPOSE.

Hi,
Well...optics start at about $2500 right????
As far as "race"....I am a direct import that is a USA citizen by duty and choice!!
