that is so tru lol I've ended up with a 85 rem mag and a 75 saum but can't keep both

I have a SF1 sendero here that is my original saum from 2002

Its done 1700 shots and still shoots under 1/2 moa with 68g of 2217 and 162 amaxs at 3080fps

I just bought a barrel in 7mm SAUM and was wondering the barrel life... Cheers for answering it for me!

if only hunting, then heaps!!
on average most of us, solely deer hunting would shoot around 50 rounds a year, and that's with a few sighting in shots before a big trip.
so at that rate it would take 20 years to shoot 1000 rounds.
if shooting goats, chammy or thar then the yearly round count will probably be slightly higher,
shooting paper or gongs and the barrel life will be reduced significantly.
work out roughly how many shots a year you would use in that particular rifle and divide that into 2000, and that will give you a starting point
on roughly how many years of barrel life you have..
also the hotter the load,the shorter the barrel life.

Also the hotter the load, the type of powder used (heat generation), how quickly firing (heat generation, bombing up real real bad) will all accelerate the barrel's demise.
If you recheck your seating depth from time to time you can also get a feel for throat advancement per rounds fired. And when doing that seating depth check if the projectile feels "notchy" as you push it into the throat what your are feeling is bad fire cracking. Better to load a 7mm SAUM to maybe the high end of a 284W performance and barrel life and brass life will be extended.
Otherwise if just having acquired the rifle if possible get access to a borescope to examine the lead and degree of fire cracking/erosion.

As Mark from Desert guns said to me- I can check it all over and it can tell ya what I see etc but it's only when you group it that the real test will come.
