7mm, something in-between WSM and 28 Nosler

[Cmrem700]

I like the 7lrm. They always have brass. Just wish it wasn't hornady.

I'm surprised the good ole 7 Mashburn hasn't been mentioned in this conversation?? Eric in DL

For belted magnums, I personally lean toward Weatherby. Probably has something to do with being able to see the factory from my "front" yard.

I'm too young, last of the baby boomers, to really know the 7mm Mashburn.

The 28 Coaster should push Berger 195 VLD at 3000fps from a 26" barrel. If you are shooting at the 1500+ yard range you will probably have an even longer barrel.

If you want something off the shelf the 7mm SAUM is the best at the moment. As far as I can tell, same pressure, same seating depth, same barrel, it will throw that same 195 pill at ~2750fps

The 28 Coaster is exactly what you asked for. Half way between a WSM/SAUM and a Nosler. Easy to make brass from any Nosler or RUM brass.

The WSM/SAUM will use ~62 grains of RL-26 to go 2750
The 28-Nosler will use ~91 of RL-33 to go 3100
The 28 Coaster will use ~83 of RL-33 to go 3000

As close to the middle as you can get.

The design is free to use. Maybe I'll make one with my Proof Research barrel instead of another 28-Nosler. That would be a 24" hunter though, so I'd be throwing Barnes 168 LRX at about 3050fps.

Unless, you are not interested in wildcats.

My 7 Saum with RL 26 and 195 Bergers with 27 inch barrel runs in the 2950 range. Amazed me the other day at 2000 yards!! I would think a 7 Rem Mag would push them 3000 Fps +. Seen some 7/300 WSM's shooting 195's over 3000 with a long throat.

It looks possible to reach those numbers with long throating and seating. Same as it is possible to take the 28 Coaster to more than 3100fps and the 28 Nosler to 3200 fps.

Individual barrels, pressures and stresses on the brass will have an impact.

If you push a WSM/SAUM to velocities of the bigger case you you negate the recoil reduction.
If you push the 28 Coaster to 28 Nosler speeds you negate the recoil reduction.
etc...

If it were me, I'd, check the original posters parameters and see if my suggestions meet his criteria.

If it was me I would just build a 28 nosler. Its the most accurate 7mm Ive seen. Customers are regularly sending me groups well under 1/4 moa out of there hunting rifles I build them with several in the .0s. That 195 berger just plain shoots in that cartridge. Heres a 200 yard 3 shot group I got today from a customer which is .138" center to center or .0659 moa. This was out of a 12 lb hunting rifle with optics and bipod.

I'm shooting 7 saum with 30" barrel and 195s at 2900. It is on a short action but it is not even close to fitting in the magazine. I have to pull the bolt to remove a loaded round. A long action would be considerably better. I would agree with Pierce on the 28 nosler. If I were doing it again that is the one I would pick.

 

[wboggs]

The 7mm RSAUM has about 74 grains capacity, and a longer neck than the WSM. Too bad that it is suffering in popularity and sourcing brass would likely be an issue.

In my opinion, all these custom options are too much work and expense for any gain you get. Get a standard cal close to your specs with available brass and dies. Load it right and never look back.

 

[rpierce]

The 195 berger at 3100+ fps is in a class of its own. It has 10% less drop and wind drift than a 300 win mag pushing a 215 berger at 3000 fps. Theres nothing hard about finding dies or brass for it either. Grab an 8 lb jug of reloader 33 and 195 bergers .020 off the lands and go shoot 1/4 moa or better groups.

 

[nastynatesfish]

Don't forget the 7-300winmag. It's a dang fine cartridge

I am with you on this.

Nothing wrong with the plain old 7mm Rem Mag. On my second one now and both are 1/2 MOA rifles. Boring old 7mm Rem Mag... still chugging along day after day.

Guess I have too many other wild cats to mess around with.. I wanted something simple. 7RM is simple.

I dont know why the 28 nosler wouldnt be at the top of the list. The accuracy and ease of tuning have amazed me. Super easy to tune, amazing accuracy, velocity is easy if you want it without pushing it. You dont have to use temp sensitive powders to get top velocity. I run a 3050 node in mine, which you can get to with retumbo. You can get over 3200 with rl33. At 3050 with a 195 brass will live forever, and barrel like will be as good as a wsm running wide open with 33. I have a saum, wsm and 28 reamers. The 28 is used ten fold for good reason

The 7 Blaser is between the two, it's like a 7 WSM long but just a little more compact than the 28 Nosler, I'll probably never build a 7 Mag again between the Blaser and the Nosler.
The 7 LRM is a complete disappointment!!

 

[Danny1788]

7mm blaser is interesting, what kind of numbers is it putting out with a 180?

Bigngreen, Im curious to know why you found the 7LRM a complete disappointment?

I wont speak for Bigngreen, but brass sucks, and velocity was no better than a 7 mag. Couldnt get close to what was claimed for speed.

 

[bigngreen]

Ya, the brass SUXS and just does not perform where it looks like it should, the 7 SAUM's I've built run about he same speeds with the same bullets only brass lasts and accuracy is easy compared to the LRM, it will go away with the 28 Nosler stomping a hole in it for both accuracy and performance.

Fair enough, seems like the general consensus on the 28 Nosler is its an excellent cartridge.
Thanks for the feedback.
