If you only had one rifle

[Noiro]

If you only had one rifle and it was Rem 700 Sendero .300 RUM what load would you use for predators at all ranges?

[bobcat]

Maybe a 180 grain Nosler Accubond. I think that would do the trick, at short and long distances.   

[300rum]

I would use the same thing I was using for big game or target practice or whatever you are using it for.  I wouldn't change loads based on what I am shooting at.  Change rifles, yes, loads, no.

With a name screen name like 300rum you would know!
Think a 150 gr Scirocco at 3450 fps will handle all WA game?

I am more of a heavy bullet guy.  Just a personal thing.  I am worried about burning a barrel up way too quick pushing anything at that velocity for too long.

If your accuracy is acceptable, then it is probably just fine.  I really don't have a clue how long a barrel would last a wild guess would be not too long or at least not long enough for me?  I just couldn't get them to stabilize well enough at those velocities and didn't think I was giving anything up going with a 180gr (at least) bullet.

No need for that much speed. A 180 grain bullet will have a higher BC and still more than enough velocity for a very flat trajectory out of that RUM. Also will do better in the wind.

The only reason to go with a 150 is if you're wanting less recoil.

I was always partial to e Seira 200gr SP BT in the big 30's

[BULLBLASTER]

With a rum you aren't utilizing it to potential unless you are 200+ grains. I would say 215 Berger's at 2950 but I can't find them anywhere... so 210 Berger at 2900 it is! Big or small game near or far. 
I have a sendero 300 rum too!

[BULLBLASTER]

I know I am just above win mag velocitys but my gun shoots them well and brass lasts for ever.

[kentrek]

the biggest fastest Berger it will shoot

[bobcat]

I surely wouldn't argue with the 200+ grain bullets either. That's what the 300 RUM is made for. You could shoot 150's out of a 308 Winchester. With the RUM a 180 grain is a light bullet.

[hillbilli]

do some checking, but i'm pretty sure the accubond and sst have the same BC, and you could probably use same load data for both, an expensive tough bullet, and a softer, much cheaper bullet.. everything else the same..

[demontang]

Id have to do with the 200gr accubond

[Biggerhammer]

190gr Berger VLD.

[carpsniperg2]

180 or 200 grain accubond.
