My favorite when used to shoot the 300UM was straight from Nosler load data.

215GM Primer
H1000
165 grain AccuBond

I always started load at about 94 grains and loaded up in .5 grain increments until I saw velocity hit 3,270 - 3,275 as per the manual...........

If going with the 180 grain AccuBond then start H1000 at 90 grains and load up to speed at about 3,150fps.

Thank you for the tip. Will give the 165 AB a try.

Thanks

The 165 gr AB should be a laser beam out of the 300 RUM.

The 200gr AccuBond is just about perfect in the big 300 RUM case. Max charges of H1000 or REtumbo would be hard to beat.

This load has been accurate in 9 different 300 RUM rifles. It has cleanly killed, 8 moose, 4 caribou, 5 black bear, 1 brown bear, and 3 blacktail deer. It is the only load I will probably ever shoot out of my rifle.

My all-too-brief relationship with the .300 RUM ended up at 95 grains of Retumbo and the 200 gr Partition or AccuBond. Terrific load!

You didn't mention what game animal you are hunting and I would assume Whitetails.

My 300 RUM load

Remington 700 BDL 26" barrel, ported

Remington Brass
Federal 215 primers
200 AccuBond, seated the length of the magazine
91.5 Reloader 25 (Nosler book, max charge for this powder)

35-degree temps give 3,060 fps, 70-degrees and above 3,100 fps +

Ordinarily I'd never consider using a bullet that light in the 300 RUM. However, you have certainly made a compelling argument. :grin:

I have not shot an animal with this load yet only paper.
It is accurate in my rifle
180 gr Nosler Ballistic Tip
Fed 215 primer
97.0 grs of Retumbo
3.657'' overall lenght of loaded cartridge
Remington or Nosler brass

When using a Barnes or other mono metal bullet you really should reduce bullet weight by at least 15% when compared with standard conventional bullet weights. So a 168 TTSX is comparable to a 200gr cup/core type bullet. Not only in physical size but also in effectiveness on game.

I really think using a too heavy/tough mono metal bullet decrease effectiveness and are the reason many have had poor results with them.

Even given my limited experience with Barnes TSX bullets, I'd agree.

They penetrate like crazy!

I had a 100 gr Barnes TSX from my .25-06 out-penetrate a most of the bullets I tested from my .45/70 Marlin...

I got a mess of 168 gr Nosler E-Tips a while back, on sale, because I figured they'd be more than enough bullet for ANY BIG GAME in North America.

Or 92.5 gr rl25

My most accurate load ever!

 

[Richracer1]

My 300RUM has become pretty much my main rifle. I like how it feels and it's easy to shoot, but does get a little heavy at the end of the day though.
Wow, looking at picture I took, I've had it 9 years now..... :shock:

 

[Thebear_78]

If your not hunting anything bigger than white tails a light Barnes at high speed makes for a good load.

I have a buddy back in Michigan who loads the 130gr TTSX at nearly 3800fps. Sighted 3" high at 100 yards he aims on fur out to 500 yards. He's not much on range estimation and says it's easier to just "put the crosshairs on brown, bang it's down!" He has used it on several white tails every year.

That's gotta be a crusher on WT's! Can't imagine how hard it must hit.

Yeah but I bet a 150 E-TIP would be poison too in the 300 RUM! Just sayin :mrgreen:
