7mm-300 vs 28 Nosler

7mm-300 Win with a 26" barrel will probably be around 3100 fps and the 28 Nosler will probably be 3150 fps. That is with all things the same and staying withing reason. I use Retumbo in both and that is what i am seeing. I am currently running the 28 Nosler at 3190 at the muzzel with 80.5 grains. But that is a pretty stout load for the rifle.

BJH what bullet weight are you using for the comparison?

He are my thoughts(I believe I already stated this so sorry if so). If you want to shoot 195s go 28 Nosler. If you want to shoot 180s go 7-300. With 180s I do not think there will be enough difference to warrant the extra powder burnt. I personally believe the individual barrel will dictate more the the cartridge will.

........There are two simple mindsets which usually occur in any discussion about cartridges:

-There are only one or two useful cartridges; the 30-06 and the 270 Win.

-The rest of the folks who think that the little improvements can often lead to some enjoyment and pleasure of creating different cases and the improvement in performance.............

I could use a .30-06 for almost everything I do. Putting it in different platforms would likely be necessary to keep things interesting.

Tweaking cases, and bullets is also fun.

It's about having fun, if it's not don't do it.

There isn't a lot out there that hasn't been done, but there's a tremendous amount of things I haven't done.

I forgot to mention that I am shooting the 180 grain Berger Hybrid out of both. The 28 Nosler is a Cooper with a 26" barrel and the 7-300 is a custom with a 28" barrel.

I came to the conclusion after lots of thought and research that the 7-300 had more pro's and less con's than the 28 Nosler. I was dead set on building a 7-300 for my next LR hunting rig. I ended up going in a completely different direction oddly enough...I'm building a 338 lapua improved instead! What finally made my decision was neither the 7-300 or the 28 offered me enough "real world" difference from my 300 win mag. I came to the conclusion that I would essentially have 2 very similar guns. Not sure if that helps at all...

From the research I had done the 7-300 was about the max you want to go for as barrel life. It offered close to the 28 Nos but everything I had read and speaking to a couple of gun builders it did not burn out the throat as bad. It's still over bore just not as bad. I have a new 7mm barrel in 7mm mag that I hope some day I can have it rechambered to a 7-300. I already have a savage 300 win mag that I want to use for the action but I also have another rifle with a shot out barrel that I'm looking at something in the Sherman line up. And yes I also some day want to get a 338 AI.

I can't find anywhere this has been discussed so lets have at it. I know Ryan at Piercision Rifles has been having great luck with the 28 Nosler lately but I also hear great things about the 7-300. I'm thinking of putting a cheap rifle together with a used Rem 700, a stock I already have, and a new barrel. I already have 300 Win bushing dies so I wouldn't need new dies for the 7-300. These new bullets from Berger and Hornady have me wanting a fast 7mm! Which one would you go with?

7-300 Win Mag. Also called the 7 mm Practical. The brass is half the price as the 28 Nosler. Look up 7mm Practical and see how it was designed. It's been around for quit some time. Was specifically designed to feed well, low pressures, and high velocities, reduces wear on the throat. 300 Win Mag brass is everywhere. A lot of the Teams guys are switching to it over the 300 Win Mag do to high BC 7mm bullets.

I have a few questions for those of you that just added to my build issues. in a 26" barrel what velocities can one expect from each cartridge using 180 and 195 grain bullets. That would be without high pressure loads in each. I thought I was going to go with a 28 Nosler and a 338 RUM now you got me thinking about the 7-300 and the 338 RUM. Someone that knows show me a apples to apples velocity comparison please.

The way I look at it is like this. If us 7 Rem Mag shooters like the 180 grain VLDs 26" Barrels 3050 FPS. How could you not love the 7-300 Win Mag with a 24" barrel 195 grain VLDs at the same velocity. I would not even mind building a 7-300 Win Mag with 22" Threaded barrel for a suppressor or muzzle break. Cause even if I can get 2950 FPS from the 195 grain Berger's should be a big improvement. If you get the 5R rifling you can get about 100 FPS back. The shorter barrels are more ridged also. I'm starting to feel a build coming on. LoL!!!

I like my 7-300 win mag, but it was built a couple years before the 28 Nosler even came out. I dont feel at all handicapped with the 28" Bartlein however. I also dont run it hot, I like to keep my brass after 2-4 firings. With that said, it shoots the 162 Amaxs at 3150fps and the 180 Eldms at 3025fps under 1/2 MOA with H1000. Rifle is a 700 BDL SS, 28" Bartlein heavy stainless 9 twist, McMillan A5, Leupold MK4 8-25x.
