Big Magnums - Marketing genius?

I agree with what has been said regarding newbies starting out with a basic cartridge. Nothing wrong with that - a lot have game has been put in the freezer with 243's & 308's. God forbid I say anything bad about a 30-30.

However - I just received back from my gunsmith a new build. It is a accurized Rem M700 and has a 30" fluted varmit taper barrel, chambered in 300 RUM. The barrel has a drilled perminate muzzle brake. The recoil is about the same as my Tikka T3 Lite in 270 WIN and the muzzle blast is "authoritive." 

I am working on developing a reload using US869 pushing a Hornady 208g A-max. One friend is pushing a 240g SMK to 3100 fps in his factory M700 LSS.

My hope is push a 208g A-max to 3200fps which would yield 32 moa come-ups @ 1400 yds (and traveling > 1500 fps) with +3moa high @ 100 yds.

If I were to attempt that with a 308 it would be sub-sonic (and unstable) at 1400 yds.

FWIW My brother's factory 300 rummy is pushing Nosler 180gr BT @ 3400fps using RL25.

Sounds like a dandy setup Chapoka. Got any pics?

Hopefully JoshT will chime in, I think his pard and himself are shootin the same boolits..

there's a 577 t-rex for sale at the campfire right now if any of you are interested. only wants 5 g's for it. it needs a bigger recoil pad for me though. i'm a sissy.

I run the 210 Berger with 93.5 grains of Retumbo for 3100 and some change in a factory 26" Sendero .300 RUM. My buddy runs the 208 AMax with 95 grains of Retumbo and gets a tad over 3200 in the exact same gun. Both have the DE Break and shoot in the MOA range all the way out to 1k.

US869 is a kick ass powder for the 240 SMK... I've had them up to around 3000 using around 102 grains I believe... recoil is stout! I shot some of the 210s and 208s with US869... but couldn't get the accuracy that Retumbo provides... and the loads with US869 seemed a bit dirty. I think that powder really needs the heavier projectiles and stout charges to burn clean.

That is a wimpy gun, I need something bigger!!!! After all I shoot such long ranges.  I need something at 6000 fps, and .70 caliber!!!!!!!   

[JoshT]

6000 fps would be freakin' sweet! The highest I've ever seen a chronograph read was 4560... that was a 40 grain NBT out of a 22/284... not a "safe" load though!

I'll find me a 378 or 460, have the bolt face opened up, put a new snout on it, be a hellava antelope gun too...

Or... you could man-up and build it in a TC Encore... like this guy!

Good thing that rifle doesnt have a scope.  Otherwise a man with a suture kit could make his weight in gold on that range with the T Rex lol...

hmmmm... the gun club I shoot at doesn't have to have a sign to remind us to "Aim Every Shot".  Based on the sign AND the video I think perhaps this is a range for the functionally retarded.

Chopaka,

Tell your bro to try some Retumbo.  It is less temp sensative than the RL 25.  I squeezed out a little more velocity to.  100.2 grains with a 180 BT was right around 3460fps.  Check out my post on "300 RUM Sharing of Data"

Hey Josh, do you know off hand what the BC of those 208 A-Max's is?

[G.R.K]

.648

[JoshT]

Hey Josh, do you know off hand what the BC of those 208 A-Max's is?

They list them at .648... but out of both our Senderos they work out to more like .700... at least that's how my drop figured out to 1K. The Bergers also clock out a little higher than the .625 they have them listed at... more like .675.
