6 PRC reloading

[TimberHunter]

I’m also wondering when Hornady will/would Sami spec the 6PRC. Makes sense for me since they have the 22/6/6.5 creed

Thanks again for the 6um heads up I checked it out but with the cost of reamer and go guage as well as more expensive dies and brass I'll be $1000 cheaper to get set up with 6 prc since my smith already has a reamer so that makes the choice to stick with prc pretty easy.

No problem. I thought the same thing, they definitely want a pretty penny. Maybe we will see some prefits floating around one day.

I think I’m going to reach out to Hornady and probably David Tubb and see what the max rpm’s are for some of these bullets. I just thought it was interesting that a 115 Berger Target at 3,400 fps was under a 1.5 with an 8 twist but a 7 twist would put it at nearly 330k

What were you findings here, ever hear back from Hornady and Tubbs?

I’ve listened to a pile of Hornady podcasts over the last year and I don’t see them ever introducing the 6 PRC to SAAMI. Their ballistician mentioned in one podcast that the 22 creed was one of the most difficult SAAMI introductions they’ve done due to how overbore it is and trying to come up with a twist rate sufficient for legacy and new heavy-for-caliber match bullets.

The same ballistician mentioned in a separate podcast that the 25 PRC was even too overbore for them to introduce, but I could see them changing their tune on that one with all the new 25 cal projectiles.

Good info. I will consider a 6PRC more heavily now… I want my next tikka rifle to be something you can’t just grab off the wall at a sporting goods store

I doubt they will unless a large market grows for it from wildcatters first like it did with 22 creed. There were numerous vendors making 22 creed and 25 creed head stamped brass before Hornady got on board.

I've seen a hornady engineer state that 25-6.5 creed is too overbore. 6-6.5 PRC is more so. I wouldn't hold my breath.

Edit: missed @mlevimadden already basically said the same thing.

Hornady said 280k-290k maximum. Someone from Tubb called me back and told me that David felt confident the DTAC would hold up just fine

It’ll be okay, but .180” would be more optimal. The .180” even works good with the 108 ELD. It’s the Goldilocks FB

What is the reamer spec for the free bore diameter? neck diameter? and lead angle? is the case body corrected for diameter to prevent clickers? It would probably be easier to just post reamer spec sheet. LOL sorry for the long question. Thanks

Idk what the FB diameter is. You’d have to ask PBB. Don’t know leade angle either.

Neck is .279, which is perfect for ADG and Lapua

It is corrected at the .200 line to eliminate clickers.

Thanks for the response. I am just starting down the 6 prc path. I have a bartlien 7.5 26" barrel, and a Win. Mod. 70 CRF 6.5 prc actiion, SAC dies, stocky's stock, lapua brass, plenty of powders and primers, No reamer or bullets. Planning to use 108 to 110 gr. bullets. I haven't decided if I want to chase the lands or go with a long "node" forgiving freebore. I find a lot of info. on everything but reamer design. If I can get good first hand info on a reamer design I will buy one, if not I will most likely rent one, and work on figuring it out my self. Again thank you for your input and to anyone else that can help.

There’s potentially some new bullets hitting the market that will probably prefer the longer freebore.
Would suck to spin up a barrel then need to run a throater to lengthen

That said all the reputable 6prc reamers have the AW2 butt and proper neck diameter for no turn necks with all available brass

TS Customs chambers 6 PRC, but has a .135 freebore. Can’t decide what I’d shoot, but I have a wide range of 6mm projectiles from 87 - 108 grains. Not sure I want to ask them to throat it long and only shoot heavies.

Good thread. I’d like to chamber up a barrel in 6PRC for groundhogs. With the availability of brass and the benefits of the magnum case handling pressure, it would be a great replacement for big legacy varmint cartridges like the .240 Weatherby and 6mm Remington AI.

The long throats are rarely a handicap
Most of the lighter 6mm bullets shoot well with a long jump just by their design so you can optimize for heavies but still get very acceptable accuracy from the lighter bullets
My 6 prc lives on 109 eld-m but will shoot 95 ballistic tips and tmks all day they’re a mile from the throat
I shot 50 80g eld-vt and they were close to 1” for 10. Yugge jump
Just good for thought

Edited to add: current freebore unknown
It was lengthened with a uni throater
109 eld-m is 2.950 COAL and jumping .030 if someone can reverse that math.

Good to know, thanks!

What do you guys think, is there any chance of a factory 6 PRC?

I'm not overly interested in reloading and given the success of the 6.5 and 7 PRC's, I'm kind of surprised it doesn't exist as a factory offering yet.

Not likely. Hornady doesn’t like doing overbore cartridges. Hence the reason they aren’t marketing the 22 Creedmoor. It’s outside of what they like to produce. They just got it SAAMI approved to prevent there being 80 variations that can’t be standardized

Nope
Maybe a 25 PRC of the 25 cm does well.

I didn't realize the same question had been asked on this page...

Keep watching, I really want to make the 6 NSI (6 PRC) a standardized thing. Including barrels and loaded ammo. One loaded with Hornady 6.5 brass for practice and others loaded with headstamped ADG brass.

I have started testing with the 140 throat and the group buy will be throated 180.

I have several powders and thousands of the 95 TMK, 108/109 ELDm, DTAC, Berger 108/115 hunting, and will buy many of the new TMK when released.

Not that I am Horizon firearms size, but their work established the 22 creed as a thing and Hornady SAAMied it with their exclusive access to ammo. Kinda like the 109/6GT and GAP. And, the 6 creed was built off of GAP wildcatting as well.

It the 6 PRC becomes a thing, it will happen like that.

I also think the 25 creed got a lot of help from the Hunter NRL.
