Hard time with my 300 rum

[shoot'n hogs]

I am having a heck of a time finding the right load combo for my 300 sendero.
I am trying to shoot the horady sst 180gr.
I have tried different col's, powder, powder wght, and primers.
What I am wanting to do is use this bullet for my general hunting and shooting and save my barnes triples for the occasional hunt (expensive).
If any one has any load data, it will be gladly noted.
Oh yeah, the best that I can bring the sst's in is about 1.25".

While that's not a bad grouping for hunting bullet and a rifle that kicks like bull-elk. I think you can get it better. What all have you tried; insofaras powder, seating off the lands, primers, etc...

My 116 Savage 300 RUM likes 80 grains of IMR 4350 with the Fed 215 Mag primers with the 180 grain Nosler BTs. I get a muzzle velocity of 2980 with this load.

While I love Hornady bullets and use more than any other brand I've not gotten any better accuracy with an SST so far. Not that good in all cases. This includes factory and hand loads. I'm still working with them to see what's going on.

BUT like the Nosler BT they really have no proper place in a .300 RUM or any of the big magnums for that matter. Don't care what the manufacturers say they just aren't proper in the big mags. They will blow up at close range at the velocity those huge cases are capable of running them. If you insist on buying and shooting a big mag then you really need to accept that a premium tough bullet is mandatory.

That's really not even .300 Win. performance. Barely more than a .30-06 Light Mag Hornady load. Why buy a gun chambered for a race horse and then run it like a walker? Just buy a .30-06, it's cheaper to feed and not much behind that level of performance.

I have to agree with Greybeard, any of the polymer tipped bullets need to be limited to less than 3000FPS initial velocity, unless one is shooting long distance (i.e. 400yds+). Big magnums make great use of the "H" style bullets, in fact the RUM class of cartridges is where they shine. Fast to open up but still having enough force to plow completely through, they make for a very effective OSS.
