6.5 saum

Im in the works of starting a 6.5 SAUM and would like to know if and body has any experience with one or knows somebody that may. I have a few reamer prints and would like to know just how long I should get the freebore. Will be shooting mostly 140 grain.

Thanks.

You coming off the 7mm RSAUM or the .300 RSAUM... I've shot with a few guys that built them.. they loved the cartridge.. most came off the 7mm RSAUM as I recall. At the time I was shooting a .300 RSAUM for a 1k rifle. You might want to use a long action.. throating it a little long will give you more powder, the longer action letting seat the bullet out, little better jump from the neck.
Now day's I think I'd do the aforementioned only just use the 6.5 Rem Mag.. pretty must the same thing and a great cartridge I might add. Heck if I was using a 6.5mm to shoot 1k with today I'd try the 6.5 Rem Mag for sure. I had an early 6.5 Rem Mag when Remington came out with it in M700 SA BDL... great hunting rifle, killed game like a gangster... but it would have been better in the long action... 140gr plus bullets were just too long for that magazine.
Good luck.

Probably off the 300 SAUM building it on a short action not worried about mag length as I will be single feeding them. I like the Rem 6.5 mag but the 6.5 SAUM just looks like it will be just right in a shorter package.

Not sure what the 6.5 RSAUM will give over the 6.5 Rem Mag.. looks like the 6.5 Rem Mag comes in about 68gr H2o I'd say the 7 RSAUM and the .300 RSAUM should be coming in at around 66gr H2o or better... that's just kinda a guess at this point.. I was shooting a 190gr in the .300 RSAUM burning 63.5grs to 64.0grs of powder in my rifle. Shooting single shot.. no problem with a SA.
I think I'd real consider the 7 RSAUM as a case for necking down to 6.5 over the .30 cal.
The 6.5 Rem Mag fits very nicely into a SA again if your shooting one at a time, no problem on the longer bullets.

I belive the case capicity on the SAUM is around 72 h2o before necked down so yes the case capicity is about equal of the 6.5 Rem mag. I would like to base it off the 7 SAUM but brass availability is a problem I have found a few places with 300 SAUM. I belive it could be sized down in a couple steps no problem this is why I chose the 300 over the 7 but yes the 7 would be a lot easier.

Re: 6.5 saum

I understand the brass problem. However it seemed like a lot of extra work just to get to a 6.5 Rem Mag performance'.., then.... that's why we play this game of guns and things that go pop!
Take care, have fun.

Re: 6.5 saum

I have a reamer print in hand and it has a 203 lead and 187 throat does this sound a out right for a 6.5 shooting the 140 class bullets.
