7mm PRC

[Scuffy]

Rifle arrived.
Started load development with N560 and 162g ELD-X
I don’t think I’ve ever loaded for such an easy calibre.
Two accuracy nodes, settled on the higher velocity node at 3082fps .3 groups.

 

[scotch_egg]

How much powder are you stuffing in the case and what length barrel?

I am also using N560 in a 7mm SAUM. 60gr is achieving the same velocity with 26” barrel

 

[Scuffy]

Not going to publish powder charge as its above book.
22 inch barrel

I’ve been following the prc line closely and it will be a good cartridge for sure. Personally I’d say not really needed for uk deer but those magnum men like a big one and why not. I’ve alway fancied a PRCW which is a 6.5prc necked up to 7mm which might be the perfect balance of recoil MV and high bc bullets. The dies might be a pain to get though I think cortina precision makes them.
Mind you I’ve never seen a deer yet that won’t die just fine with a 6.5 bullet placed correctly and mine is lethal to further than I ever shoot (should do the business up to 600m theoretically ).

That is surely, based on powder capacity and bore size, just a .280 Remington for short actions?

It's about F open really, getting top end 284w velocities without the pressure, case life extension etc.

I was more commenting on @Utectok’s suggestion of a 6.5PRC necked up too .284.

The 6.5 PRC has a very similar capacity too .280 Remington, so necking the case up is goi g to produce a short action magnum bolt face .280.

The .280 is very close to .284, as you know, it just runs in a long action and burns a bit more powder for similar velocities but at lower pressure, which would give you your better case life.

The point being it would do what @Utectok is mentioning without the need for difficult to obtain dies.

I think 7-6.5prc is the current darling for the F class shooters m.
I think they call it 7prcw in the states

Aye, I should have clarified, that's what I was referring to, the necked up 6.5prc variants.

I’d be interested in a 7-30 PRC as a replacement for my 30-06 but with just a little more gas…

If it's been done, it'll be on one of the US forums..likely has.

7-300 PRC, Pretty Impressive

Here are some results for my 7-300 PRC. I actually built two of them. Both are dressed with AG Composite stocks, trigger tech diamond triggers, Nightforce NX8 Scopes. Bartlein had an TBAC Ultra 5 and the Proof had a Cortina Tuner Break. The Bartelin dressed weighs right at 10 LBS, the Proof...

Hah, thought I'd read of it done.

A lot more gas. But with a much shorter barrel life, like sub 1000 rounds.

A guest at our club brought one along, it’s a beast but he was talking around 600 rounds to burn the barrel out.

 

[Tobyc064]

Should be able to get near 3000fps with n565 and 180’s . 24”

Happy with mine with rs powder

What bullet are you using?

 

[PEA]

What bullet are you using?

175 eldx.

 

[scotch_egg]

175 eldx.

I would use that bullet but the are exceedingly long and eat into powder space for the 7mm SAUM.

I am also interested in the speed you are getting. Factory ammunition is reportedly very slow.

If doing it again the 7mm PRC is the way to go.

I have saw a lot of videos stating that factory is very very slow.
It’s a cartridge that you must home load for to get the performance out of it.

Not had chance to check the speed bu Will probably be over 3k. Correct they are a long bullet but it all fits in and not compressed.
