Re: Anyone shooting the 300Rem.S.A.Ultra Mag.
In case you guys haven't heard the recent rantings of my 30 Gibbs exploits, I will throw them in now.
Performance is identical to the RSAUM and a bit behind the WSM. I shoot 165gr SST at 2950fps with a max vel just under 3100fps. Sound familiar. I bet the amount of powder used would be almost the same. Case volume certainly is.
I call this my long skinny magnum. So for those who don't mind a 1/2" longer action, unlimited supply of cheap brass, a bit of fireforming, and a few extra rds in the mag, the Gibbs might just outlive all of them.
