28n, 7rum, 7stw decisions (7rm falls far behind)

Yes they are based on the coal of the 30-06 so would work in the same magazines and actions

I conversed via email with the Nosler ballistician tasked with the xx Noslers just after the 26 was official. Just lucky and we had a great conversation.

A xx Nosler or STW or RM will not feed in the same magazines as a 30-06. Well, not without modifying feed lips which depending on the make and model of the action may be part of the magazine or maybe an insert in the bottom of the action. If the rifle has a removable magazine then my statement is true, will not work without modification or substitution.

The only thing that the xx Nosler line has in common with the 30-06 is COAL. That does not mean the COAL is based on the 30-06 COAL. What we discussed is the COAL is based on the Nosler M21 rifle COAL capability.

Argue if you like. Doesn't change facts.

I have a couple of friends that are shooting the 143 Hammer Hunter @ 3500 to 3600 fps with awesome results in accuracy and terminal performance. I think this is the direction I'm leaning for this project. I don't want to hassle with throating it longer for 195's which I feel is best for that bullet. I currently have a bunch of Berger 175 EH bullets. If I don't go with the 143 Hammer I'm thinking of making a go with the 175. Anyone else shooting either of these 2 Bullets? I'm thinking light and fast.

I shot 143 Hammers from my 7stw, 3470 fps. I didn't have the accuracy that the N570/195's gave me but those Hammers worked really well on Elk and Deer. Keep the poi back off the shoulders LOL.

Thanks for your report. What distance?

Of the three I would and did pick the 28N. Make sure your rifle will take 3.600" in the mag box at the absolute minimum.

So by that reasoning...the .338LM is based off the .30-06 case...

Not any difference than tweaking feedlips between the wsm and prc/rcm. Diameter comes to play as much as eum and wm cases

Having owned the 7RUM & 7STW, haven't owned a 28 Nosler, but did build a 7-338RUM and did all load development on that rifle, all I can say with complete confidence is this; barrel life is determined by WHICH powder you use, speed of fire and cleaning regimes.
I bought ALL the jugs I could find of Win Supreme 780, in the end before it left the shelves, I had 12 4kg jugs, it is the best magnum type ball powder I have ever used. No other has ever been available here since 870 disappeared 30 years ago.
Now, throats show minimal wear using this, moving to RL25 and throats are moving double the amount with the same number of shots. I got my first 264WM in 1988, barrel lasted 1500 rounds with excellent accuracy, just another 50 rounds had doubled the group size, from then on, accuracy got less and less. This was with 7828 exclusively, yet my recent 264WM (2019 purchase) has been fed H1000 and barely looks fired at 600 rounds.
My conclusion is that yes, bigger cases burn barrels, BUT, if you choose powders wisely, keep rapid fire to a minimum and clean the barrel back to shiny metal, they last longer.

Cheers.

I had a 7STW for a few years. Barrel.life was just over 600 with FAST 160s.

I have a 28 Nos now. It only comes.out of the safe for elk season. 86 rounds down the barrel. 195s @ 3099fps. I expect about 600 rounds max barrel life. I have loaded for a bunch of these. Running a 180-195 @ 3100-3200, I have seen accurate barrel life range from 400 to 700 rounds. Keep a bullet 3050 or so, and you MIGHT get 800 rounds of accurate barrel life depending on how you shoot it.

I have a buddy who is on barrel #3 on his 7RUM. 195s @ 3200. His barrels last about 400 rounds of accurate life.

If you want 1000+ rounds on a barrel, 7RM or 7PRC, .284 Win.

If you want 1500+, 7SAUM, .280AI, 7SS, Etc.

If you want 2000+, 7-08, 7SWC, 7SAW, etc.

This is 100% correct. 28 N throated for 195's
For killing **** way off
6GT and 6.5 SAUM and 6.5 Creedmoor for fun

But that does not make it "based on" a 30-06.

real close, less than 100

There is much less of a difference in body diameter between a WSM (.555") and PRC (.532") (.023" diff) case than a Nos (.550") and 06 case (.471") (.069" diff).

But you are right. If you get a WSM mag, you do need to tweak it just a hair.

i never said it did. post was about feedlips and compatibilities

Wasn't at you. Some other dude was saying stuff.

I wouldn't do an STW unless you have brass.

Hello Bob,

We will be pursuing 7STW this year. Unfortunately, as of this email we do not have a timeline for availability. Please follow us on Instagram adg_brass and / or check back in a couple of months for an update.

Thanks for your interest in ADG!

Best regards,
