The 300 RSAUM will push a 210g Berger LRBT at 2800fps from a 28 inch barrel.
I used Rel 22 and got it up to 2900 but it shot better at 2800 so thats where I run it.
We scoped it at 900 rounds and its just starting to "speck",with no checking yet at all.
I have cases that have been fired 12 times and some of them I did my ladders test and im still usuing them.
The 30 Degree shoulder is pretty easy to use and I havent had a problem just bumping it...just enough to keep the cases fitted just so.
30 degree shoulder,no belt,long neck.Tuff as heck case head.
Little to no case length growth.... I never trim...Short fat powder column.
Just a short fat 30 cal version of a 6mm PPC.
Its simple and it works.
Kicks ass at 1000 yards..
