7mm Moses

[remington jim]

I see a fellow on face book on the 7-08 site is bragging up his 7mm-08 MOSES cartridge . It’s a 7-08 rem with the shoulder pushed ahead case blown out and a steeper shoulder angle . case capacity is 63 grs . He’s claiming 3060 FPS with a 162 gr bullet over top of Hunter powder . 2.958 COAL 27.5 “ barrel

Now a 284 WIN. Which looks nearly identical to his Moses With a 65 gr capacity will not do that SO what’s the MAGIC ? What am I missing ? . RJ

A 7mm-08 REM AI has a 55 gr capacity .

The magic is brutally high pressure. There is no free lunch in reloading.

Lol. Yea I asked him what psi he THINKS He gets ? Waiting for a answer RJ

Someone playing around with a moderate sized case, improving it, probably owns more than one rifle.

If you want 7mm rem mag performance, buy one. The money saved would probably fill up your gas tank...probably.

27.5 " barrel is key here .....

what does a 284 or 280 run with a similar bullet and similar barrel length ?

 

[burnt_servo]

so did some poking around at imr ..... seems like the 7mm mag with a 24 inch barrel is just hitting 3000 fps ...

mr super dude better say good bye to his hand , because he is holding a bomb

This. Like most of our wildcats, sadly, concrete velocity and pressure data is hard to come by. - dan

Yupp. Looking at Nosler load data for 160gr bullets I see the following:
7mm Rem Mag, 24" barrel: 80.4gr water capacity, 3063fps w/70gr RL25, 3072fps w/72gr Magpro
284 Win, 24" barrel: 58.0 gr water capacity, 2757 w/55.5 gr H4831sc, 2816 w/55gr Hunter
7mm-08, 26": 47.6gr water capacity, 2759 w/49gr Hunter, 2780 w/47.5gr RL19

Now, I suspect the guy is measuring capacity by filling to the case mouth (which is not how Nosler does it) so these capacity numbers are not directly comparable... But it is clear to me that there is no way in hell you are going to hit 3060fps AND keep pressure under 65k with a modified 7mm-08 case.


Reminds me of the Sherman cartridges...

Possibly ignorant question but wouldn’t that basically be a 7mm SAW?

Depends on the demensions, but its certainly following the same train of thought. And WTO only claims 2850-2900 from a 26" pipe...

Not a ignorant question at all - yes it’s very similar for sure RJ

The cartridge name says it all...

I’m really SURPRISED that more from here have not chimed in ! RJ

It's so magical the primers decap themselves!

I guess it's just not that interesting or impressive. It doesn't outperform anything that is readily available (like the 7mm RM), and it likely has an abysmal barrel and case life. So it's a niche cartridge with limited advantages and major disadvantages. Woohoo?

 

[remington jim]

Now he’s claiming All this and only 62 psi ! RJ

Probably just a FAST barrel RJ

 

[shockman]

Guys! guys! I have an idea! Lets re-invent the wheel and see if it goes round and round.

 

[remington jim]

Face book guy has. 277 and 308 Moses cartridges now too ! Parent brass is 308 Win ! RJ

 

[Unholysavage]

So exactly like the 277 Sig Fury, but without the annoying steel case head?
I'm just going to go ahead and pass on that...
