Help me out with a 7mm build.

[86bowhunter]

Building a new 7mm to have as a travel gun. The first trip for this particular build will an alaskan moose hunt.

So already decided on:
1)7mm cal
2) proof barrel likely 24" barrel possibly 26" if the stars align.
3) shooting 180gr or 195gr bergers

The question is.... which cartridge?

I went in this originally intending on a 28 Nosler.

Then I thought about what a 7-300PRC would be like. But so far only managed to find one article on one by sniper hide.
I believe the 7LRM is a very close relative to what a 7-300PRC would be.

I'm a fan of the 7mm over the 30cals and I already have 1000 7mm bergers on the shelf. But! Nothing's ever set in stone. Might say screw it and do a 300win.

Anybody out there shooting the heavy 7mm bullets I'd like to hear your thoughts.

Compared to others on here I guess I am still in the stone age but I took a 28 to Africa with 175 nosler partitions and it was a real killer. Up close or far away. A nosler partition. What is to say? Always work. Now if you want to shoot real far I do not have any experience with them but others have liked the 180 eldm.

I've shot the 195's and 180 ELDM's in a 28 nos (terrible barrel life), and a 7-300 wsm that replaced the 28.
Both bullets are incredibly accurate but I would personally pick a better bullet for hunting, especially moose..
If you're planning on LR hunting big animals I'd recommend a 30 Cal.
I'm sending the 200 grain Edge TLR at 3050 in my 300 PRC.

Are you wanting to reload for all or have the availability of factory ammunition as well?

I have a 7 Dakota and am very happy with it. Mine has an 8.25 twist and I had it chambered for the 175 nosler ABLR's and have been playing around with other bullets. I wish I had a little faster twist to shoot the 177gr Hammers though.
There are a lot of great cartridges in the same ballpark as the 7 Dakota and when I put a new barrel on it will be chambered in one of the similar cartridges depending mostly on brass availability.

 

[Terry Balding]

What are your requirements?

I have a .284 Shehane, and a 7 SAUM. Not unhappy with either.

Thanks for the reply.
The barrel life and brass options or rather the lack of the two are really a downside to the 28. But! That's what you get when have to burn that much powder.
The 7-300PRC came to mind wondering if it would be a more efficient cartridge.

I reload everything.

My requirements are pretty fluid. I basically want to find a 7mm cartridge that pushes a 180 or 195gr bullet out a 24" barrel in the most efficient way possible. Which I know is pretty vague.

I guess if I had to describe it. 28 nosler results without being confined to nosler brass and terrible barrel life.... for example "if" as the snipers hidereview suggests. Say a 7-300PRC gave results similar to a 28nos. But burned a little less powder and or gave a few more rounds on the barrel. Then the 7-300 would be my pic.

If that makes sense.

I did consider a 7 SAUM.

7-300wm, 7-300 prc or one of Rich's 7mm flavors would be my choices then.

 

[elkaholic]

The highest velocity with effiency is the 7 max at 2900+ with a 24" barrel. A 28 nosler wouldnt do a lot better at that length and barrel life would be half!
The 7ss would be next and most efficient but at 2850-2900' with a 24"
This with 195 grain Berger

 

[Terry Balding]

The most efficient!

That's much clearer. I consider that, the most fps VS powder load.
The .284 would be first, and the 7 SAUM second.
You can get 2850 or more from a .284 with 54-57 grains H4895SC.
The 7 SAUM will do 2950 with 62.5 H 4895SC. Both with 184 grain bullets
