Some of this will vary depending on barrel length,and type of barrel;but across the board these cases all give up the velocity easier than the smaller capacity 7mm's,especially with 160-175 gr bullets.
Hey Bob, when did the 7RM become a "Small 7"?

Haha, I was just going to say that the 7RM went from being a "Big 7" to a "Small 7" about the same time you were introduced to the MSM *grin*

I like my lil' popgun 7 WSM. I get velocities right in line with Jordan's. It's not hard to get excited about +/- 100 fps. On the other hand it's not hard to not get excited about it, either.

I've been in contact with Gunwerks about their 7mm LRM (7/375 Ruger). It is essentially a 7mm Dakota with a .532 bolt face. Dies are available and supposedly Hornady is coming out with brass in Feb/Mar of this year. 180 VLD at 3100 w/o the magazine constraints of an STW. There's alot to like there...

Age and maturity do tend to help us out a bit. Back a couple decades or so ago when I was in my 30's I thought and thought was the key word I thought I had a good grip on things. Now that I'm approaching mid life at 53 I realize all to well how lil I know... Dober

Someone finally woke up!They probably read about the Mashburn.... Jordan/Jeff: You have to think about it like this....these larger 7mm's do with a 175-180 gr what the smaller one's do with a 160.....and with a 160, what the smaller one's do with a 140. As to powder charges,they burn a bit more, but less than many 300 mag loads....I figure 73 gr of H1000 is not a bad trade off for 3075 with a 175 gr bullet. Whether we need it or not is another matter...not up for discussion.

I just had to enter the dog fight.
A big 7 on the .375 Ruger case is a nice thought but you can't shoot anything else in it if you lose your ammo. Using the Mashburn you can run 7 Rem and 7 Roy in it if your luggage goes to London rather than Wyoming.
Maybe that isn't a consideration but for those who travel it is something to ponder. 7 Rem is available just about everywhere and makes reasonable backup ammo.
Wonder if those thoughts are too practicle for a rifle loony?

The balance between powder consumption and bullet speed sits differently for everybody, but I'm perfectly content to burn 9gr less powder per shot and get 70fps less velocity. IMO, 3000fps with a 175/180gr bullet is a winning combination.

Barrel life would factor heavily into any "big 7" I bought.

Bob:
There has been at least one Mashburn on our local public range that someone inherited from a GF. The fellow was shooting it and someone asked to see it because the discarded brass looked weird. The young fellow was using 7 Rem in a 1950's Mashburn custom. It blows the shoulder forward and makes the neck very short.

Gentlemen, can't all this discussion about "which Big 7" be put to rest with this simple solution:
drum roll... ... ...
A 7mm Mashburn Super necked up to 8mm!!!
The 8mm Mashburn Super!!!
Now there is a Looney's Cartridge!!!! Stoke Nosler's 180BT in it and you are off to the races...

From Handloader #200 Aug/Sep 1999:
Today�s shooters regard the 7mm STW as the cutting edge of modern magnums, but it�s almost exactly the same round as the 7mm Mashburn Super Magnum that Field & Stream�s Warren Page used all over the world in the 1950s, and basically the same as the 7mm-300 Weatherby wildcat that�s seen use over the past couple of decades. All three are "full-length" belted magnums, derived from the circa-1912 .300 Holland & Holland case, so have almost identical powder capacities and ballistics.
Don�t get me wrong. Layne Simpson�s dream-child obviously provides velocities a notch above the 7mm Remington and Weatherby magnums, though it doesn�t outdo the Mashburn round, even back when Warren Page filled its case full of war-surplus H-4831. But Layne�s variation uses the 8mm Remington Magnum case, with no need to be fireformed like the .300 H&H brass Page used, and is much cheaper than the .300 Weatherby cases needed to make the 7mm-300. An STW fan just needed to run an 8mm case into an STW die and presto! Super Seven!
