The 30 Sherman Mag version will equal or exceed the Nosler and thats with Hornady brass so with ADG brass, it should be even better.

Are you thinking barrel life will be about the same as the 28nosler?

should be similar but potentially better with a longer neck and 40 degree shoulder
My first 30 sm had 1600 rounds and still going strong

Sounds like a wild cat a friend did off the 28 nolser case. Made the neck about .100-.150" longer and blew the shoulder out to 40°. It pushed 195 bergers as fast as my 28 and was just as accurate. When he switched to 180 eldm's the thing was shooting 3/4" at 400 yds.
I would be interested if I could get a barrel for the Howa 1500 action I mentioned in my 7mm-300PRC post.

Thanks. I can see using a 375 Ruger parent case, I think.....
The rounds I worry about are like the 6.5 PRC. Great round, but the parent is dead. I sure hope after 5 years that 6.5 PRC doesn't have the same fate.
IMO, a great new round starts on a popular parent....I suppose this is old thinking as it seems like it is almost easier to develop a new round than grow an old one by changing the throat and bullet selection!

Can you post a picture of the 30SM compared to a Nosler, rum or similar?

sorry but I dont have either. I can describe the difference. Both the rum and nosler are . 550" diameter and have rebated rims while the SM is .530" with no rebate. The rum is longer, has more body taper and a 30 degree shoulder.
The Nosler is slightly shorter, has more body taper, and a 35 degree shoulder.
The SM has a 40 degree shoulder with very minimal taper and a longer neck than the others.
