7 PRC

[Guy Miner]

Well, it's officially introduced. Gavin has been working behind the scenes to build a pair of rifles in 7 PRC, but couldn't talk about them until Hornady officially announced the cartridge.

He built one hunting rifle and one heavy match rifle. Here's a link to the story & video: https://ultimatereloader.com/2022/10/26/new-7mm-prc-complete-overview/

Gavin did a great writeup. Hopefully more companies take note of this cartridge and produce ammo for it.

Would've been nice to see a comparison of the 7 PRC to the 7mm STW and the 7mm Ultramag instead of the 7mm Rem Mag.

Its direct competition is the rem mag...

Good story and video Guy.
The 7 PRC does have a shorter case than I would have thought. Looks to be a great new cartridge.

I'm hoping to shoot at least the lighter of the two rifles tomorrow.

It's rough, having to shoot Gavin's custom rifles, but someone has to do it.

If you can't spend his money shooting his ammo is the next best thing Dan.

I just watched his video a little bit ago. Nice rifles, and I really enjoy his channel. Always great to see you on there also Guy! Looking forward to seeing you try those out on his channel.

Very interesting! I think I am going to have to study this out some more. It appears that I could convert my 7mm RM by "simply" swapping out the barrel (after trueing the action). I would just have to order the faster twist barrel. Correct? Dan

Great video as always. A LOT of information provided.

I think they would have something if they left the case as a full length 300PRC.

It’s about a four hour drive for me to come up and lend a hand, you’ve buddies who would be happy to help you out. I’m just sayin…..

Gavin has a series of videos coming out re the 7 PRC

Check the channel, I think he's got five or six planned, and three posted up already.

The eagerness to help a buddy is almost more than I can bear!

If the Military would adopt this 7mm PRC for there sniper rifles it would become a classic for the next 100 years.

These parameters were exactly what my objective was when I started my 7mm RM project.

A 5R rifled 26” 1:8 barrel, long magazine that lets me load out to a 3.615” OAL, and 3k with heavy high BC bullets. I also wanted it to shoot mono’s well. It’s my opinion that the fast twist helps the E-Tips I shoot expand wider and more quickly. This is just my opinion because of different articles read.

Seems like they looked at what I wanted and packaged it into a factory rifle platform. The build was a success. I get accurate performance at 3003 fps with 175gr ELD-X’s, and a hair more with Berger 180gr Hybrids. I got to where I wanted to be. It however, would have been MUCH easier to purchase a factory platform that had my performance objectives designed into the cartridge from the get go. That being said I wouldn’t switch to the 7 PRC because of brass demand. I’m good on 7RM brass. I think the 7mm PRC will be around a while but brass will be tough to come by.

I think that you are onto something there. The E-Tips, and other mono-metal bullets, tend to be long, and can be pretty tough... Spinning 'em faster seems like a good move.

Maybe I’m nuts but bullet expansion takes place over a total time of a couple milliseconds. At 3000 fps a bullet from a 10 twist barrel is turning 216,000 rpm’s. The same velocity bullet from a 8 twist barrel is pushing 270,000 rpm’s. I have no evidence it’s true but I think the centrifugal force aids in mono expansion. After all you can tell the direction the bullet was spinning by looking at the direction the petals are canted on an expanded bullet. Like I said, it’s just my opinion. Im sorry to veer the thread off in a weird direction.

Back to the subject of the 7mm PRC. The 7 PRC has the qualities many of us build into our 7mm Rem Mag projects. I’m surprised it has taken this long for it to be released. Great platform.

Bingo…. Basically replicates the old Mashburn.

I like the cartridge a lot. Ain’t much to not like with 175’s at 3000 from a factory load without a huge case and a 26” barrel. It’s what all of us guys have been trying to get to for years with Mashburns and tuned up 7 Rem Mags.
