The 280 Sherman will push a 180 well past 3000 with a 180. It uses the same brass as the A.I. and in fact, you can easily fire form the A.I. brass. The case has less taper than the A.I. and shoulder is forward but still has a .310" length. I have reamers and dies in stock also.

Thx for the ad Wolf. I'd like to make a correction and comment. The case capacity on the SS is only 72 grains with the new /B chamber which is about a grain less than the saum and maybe 9-10 short of the wsm depending on brass. Also, if handloaded, the saum will come pretty close to SS velocity...

Id say its considerably more than that!

It will do that with ease. Thats a fast powder for the sst, but it will run that fast on a lot of different fuels. Probably start around 50 grains.

The 195 would reach 3000' in a 24" barrel with N570 but most other Good powders about 2925'

Weve learned to keep the load down the first firing because you get false pressure readings due to the case moving in the chamber. Not good for case stretching either.

We were running the 175 EH a little over 3000' with N565 this fall. I need to test it some more. It was looking pretty good.

We have several getting 3000' with about 61 grains and will max a little higher

We've seen SEVERAL proof barrels that pressure up early! When they're good, they're good, but Ive not seen others five lower velocity with similar loads!

I am a new member and posted under same but was told to move the thread here. My name is Rich Sherman and am the designer and developer of the Sherman cartridge lines based on the LA 270W case and the SA Saum case. I have chamberings in 6 mm thru 35...

The brass is being shipped this week and will be posted again on the site shortly

Only rental/purchase now but I can recommend a good smith if you want? You need a 3.750 mag length. No plans for another reamer as of today.

Reamers are now for sale at Shermanwildcatcartridges.com
