How Does the 300 Win and 30 Nos. Compare

[Danny1788]

Broz have you thought about necking up 28nos brass to 30cal? it would be a shorter neck but a little more case capacity....

Thanks. But in the past I have been through the gauntlet on many wild cats. From 30 Lapua's , 30-378's , 300 Rums , even a 7 Lapua and a 257 -300 Weatherby. So I am being very careful not to go over bore. I love the barrel life the 300 win mags offer , and 3035 fps with a 215 and a G1 BC of .696 is a hard combo to beat. I am having a very hard time leaving the 300 win for anything else. Its a "been there done that" thing. But with a tried and true 28" 300 win mag in the safe, I can see the value in me stepping out of my comfort zone and building a 30 Nos. for actual side by side comparison. So, I think I will stick with a factory chambering. It will either be another 300 win mag or a 30 Nosler. From what I am hearing about the Nosler brass being so good, my grip on the 300 win mag is slipping.

Thanks
Jeff

....Very interested in the project. I have some Nosler .300 Winchester Magnum brass I'd send your way if it would help your side by side.

I will keep that in mind. If I pull the trigger on the 30 Nos. I will need brass and dies. Going to look and see what dies are available today.

Thanks

Regarding "soft" Nosler brass. It be the same as Norma and Weatherby. I like it, some don't. I've not killed a case yet, unlike R-P RUM cases.

Regarding barrel life. I see the 30 Nosler as very close to the 300WM, maybe a little shorter life but not much. The barrellife.xls says 100 shots difference.

Brass and dies are in stock at MidwayUSA - Shop Shooting, Hunting, & Outdoor Products

It has a little more pep than a 300WM but the big selling point is that long bullets can fit mag length.

but

Brass is expensive.

Thats the part I like. Barrel life for both of these options is very good. I feel they fall right in line, just before the point of the dreaded big case diminishing returns club.

Does it have "A little more pep" than a 300 win? Thats what I hope to learn. How do you know this? Will the 3.5 gr extra capacity equate to more velocity? This is my question as I don't compress now in a 300 win max load. If the brass is as soft as Weatherby and Norma it will be short lived at a max load. At least that is my experience with dozens of Weatherby's owned and loaded for. Will stronger available brass for the 300 win level the playing field? Could the stronger brass for the win allow a slight velocity advantage over the Nosler? These are questions we need to answer with a side by side comparison.

I looked on midway for the dies. Looks like the better comp sets are special order. Drat!

Who else makes 30 Nosler brass, anyone?

Thanks
Jeff

• It has a little more pep: ~50fps
• I have some brass with 5 firings, no signs of loose pockets even from brass that was obviously stressed.
• I know this because I've been shooting my version 300/26-Nosler for quite a while now. The real 30-Nosler looses about 1.5 grains to the 300/26.
• I just don't seem to have the problems with Norma/Nosler/Weatherby brass that some of you talk about.
• I can't do a side by side as I don't have a 300WM and I'm not likely to ever get one.
• Norma (same)

If you "worry" about barrel life, soft brass, brass availability, tooling availability and alternate sources, perhaps xx-Nosler chamberings are not for you.

BTW: It's not that hard to make xx=Nosler brass from xxx-RUM brass.

 

[Broz]

Thanks, so the 26 case only gains 1 1/2 grains over the 30? How about the 28? I have some 28 Brass coming so I can check volume, but curious.

What bullet and velocity you getting from your 26/30 ? and what altitude please?

PS, I would not say I am exactly worried. I just am researching before I make the decision. There is a lot of hype about the Nosler chamberings. I want documented real world results to make a decision. "Worried" not really I am already thinking of a second tube for the same rifle in case I want to switch after I see the truth.


Thanks

Jeff, the 26 and 28 Noslers are the only two that are the same dimensions for head spacing, Dave Kiff has put out a lot of bad reamers for all these Nosler rounds so there are some mix and match stuff going on that has caused some issues but if you track the 30 all the way through all should match up well, I've been using Redding dies for the Noslers and as usually mucho happy! I tried a set of the Redding hunter series dies on the last one and it makes for an excellent package for the money. Nosler did a good job with some of these, I have no love for the 26 or the 33 but the 28 and 30 are hitting just the right balance.

The "real" 30-Nosler is ~0.050 shorter in body, case length is the same.

My range is 275' ASL

I shot lots of bullets in my 300/26-Nosler and have on the to do list to try some more. Specifically the Hammer Hunters.

You would need to be more specific about bullets. I can give an example: I think I sent the CEB 180 MTH down at 3100fps from a 24" barrel.

Unless you already have a action with a standard magnum bolt face a 300 Norma (or Imp) is another good option. My improved version shoots the 230's at roughly the same velocity you shoot 215's but it's throttled back considerably because it shoots itty bitty groups at 3045fps. The down side is it takes a good deal more powder than a 300wm. A unfired 300 Norma case is 103grs of water capacity. My improved is 110.5grs fired. It's the most accurate 30 caliber magnum I've owned or built though and is quite similar to the 300 Hulk that owns the 1000yd light gun 5 shot record. I've probably built nearly 40 .30 caliber magnums for myself in the last 24 year.

If you still have a good stash of Lapua 300wm brass I probably wouldn't go away from the 300wm unless you just want to play around with something different.

Another option is a 300wsm on a LA. I built mine because it's starting to dominate 1000yd BR for the .30 caliber magnums and barrel life is suppose to be 50% better than all the others including the 300wm. I guess they get over 2000 rounds of accuracy life hot lapping 10 round groups. I shoot the same 2950ish fps that the two 300wm's I built this year for friends shot. This is in a 26" barrel and I only use 69gr of powder instead of 77grs.

Thanks for the info. I know there is a lot of interest for the 300 Norma, and the AI version, but I really choose to stay away from the larger cases. If I was going to do a big 30 it would be a 30 Lapua AI again and have it all and then some. There is some merit to running a big case soft, but barrel life we all know will be less.

It is going to be a 300 win mag or a 30 Nosler. I think I need to just document the real difference in the two with the same bullet side by side. The interest in these Nosler chamberings is huge. I think it would be a great review that would attract lots of attention. And in the end I will know for myself just what the 30 Nos. has to offer. If it does not suit me I will simply rebarrel to the 300 win mag.

Thank you
Jeff

I'm curious, what bullet/weight are you shooting at 2950ish out of the 300wsm? I have been thinking of building one but on short action.

 

[IdahoCTD]

215 Bergers. I'm going to build one on a short action but with a Bainey mag box (3.110" ID length), a Edge fill Game Scout, and a #3 Bartlein. next to see if I can get the weight down near 8 3/4lbs with a VX-6 3x18 for a backpack gun. I'll have to throat it about .100-.110" shorter to work in the SA so I'm not sure what I'll give up for velocity.
