300rum?
 

hello everyone just bought a 300 rum in a 700 bdl looking for an accurate loaded with 180 to 200 grain bulletts i want to stay heavy because i am sure accuracy with lighter bulletts is not so good

RE: 300rum?
 

How did you come to that conclusion?Some 300ultramags are more accurate with lighter bullets than with heavier bullets.
My own choice for a hunting load is the 180gr tsx ahead of r-25.The muzzle velocity is 3380fps and groups average about 5/8" at 100 yards.

RE: 300rum?
 

96 grains Retumbo nets 3200 FPS with a 200 grain accubond in my buddies 300 RUM. Max charges in my Nosler manual are:

91.5 Grains RL25 at 3185 FPS
95 Grains Retumbo at 3187 FPS
98 Grains Magnum at 3191 FPS

The 200 grain accubond has a .588 BC and nearly identical in trajectory to the 180s because of it high BC.

RE: 300rum?
 

I think that 200gr Accubond has a BC of .588, I like that! Personally I wouldn't go lighter than 180gr and would prefer the heavier 200gr in such a hot 300 cartridge. I really don't see the point in going lighter unless niether would shoot accurately, and I'm pretty sure you could get a 180 or 200gr to shoot well.

RE: 300rum?
 

A 168gr tsx will out penetrate the 200gr accubond,and will produce less recoil as well.I would have chosen the 168gr tsx myself,but the 180gr tsx shot more accurately in my rifles.A friend of mine uses the 168gr,because it is more accurate in his rifle.

RE: 300rum?
 

the way that i came to that conclusion its just that most often very light bulletts in a large capacity case are not very accurate

RE: 300rum?
 

first I ever heard that one. I loaded extensivly for the 300RUM, actually 3 different ones and found one loved 168gr sierra matchkings, and one shot 190gr better and another one shot 168gr to 200gr matchkings evenly.

RE: 300rum?
 

You will just have to see what your rifle likes, one ofmy buddies 700CDL that was just slightly accurised, bedded the action and floated the barrel channel, loves 100gr of Retumbo pushing a 180gr TSX, it will group .5 off a Lead Sled. Another buddies 700 that was fully accurized and rebarreled shoots better with BMG, besides, experimenting is half the fun!.

RE: 300rum?
 

Well my Rum never heard that and shoots 150IB's @ 3600fps into .75"

My main elk/bear load is a 168TTSX @ 3450fps via Retumbo.....this one makes stuff dead in a hurry!

300rum
 

I allso shot the 300RUM mine is a remington SPS Stainless I shoot nosler 180gr accubond and today I found a load with nosler 150gr E-Tip. Tryed the remington 150gr scirocco bullet I ended up takeing them apart reweighed the powder to 93gr's andput them back together and now they shoot 1/2 inch groups. when I took them apart
the weight was between 93.5gr's to 95.8gr's I read an article soom were that remington used IMR 7828 in the 300rum in the nosler reloading book there max load for IMR 7828 was 93.0gr's. Now I just need to find loads for used brass in the 300 rum.

Any reason you think your load would be different for brass that's been fired?

Not necessarily, it's just overkill and a waste of powder. You'll either blow the bullet outright or it'll fragment explosively because you impact with too much velocity.

I shoot 110gr V-Maxes in my 300WM for coyotes simply because I haven't put together a .243AI yet specifically for that purpose. THey shoot 3800fps, you could get them over 4000 out of your RUM. THey are accurate as all get-out.

The lighter bullets will also burn your barrel faster, which is why I don't shoot them much in my 300.

There has never been one case of a bullet blowing up out of the barrel.

Proof?

"If you spin your bullets too fast, this heats up the jackets and also increases the centrifugal force acting on the jacket, pulling it outward. The combination of heat, friction, and centrifugal force can cause jacket failure and bullet “blow-ups” if you spin your bullets too fast."



Push light bullets too fast in a barrel with a fast twist for heavy bullets (ie many magnum rifles), and you'll see it. Especially since light bullets are often thin-jacketed varmint designs. They can't hold the RPMs.

You can get bullet skid, but thats not a blow up. Total BS myth.

Gotta agree on the 168gr TSX in the RUM. My go to load is clocking right at 3370fps out of my RUM and I pushed three of these thru a moose this fall. Penetration was very impressive, one went stem to stern on my bull. Talking over 5 feet of penetration, entrence in right ham, exit out front of chest on left side, Also placed one at a hard quarting angle thru the pounch and out the far shoulder right at the shoulder ball. actually pushed grass out of the exit wound. Range was about 180 yards.

I could push that bullet faster but have found excellent accuracy with this load, sub .5" groups with reasonably consistancy and always under an inch. 300 yard groups averaging around 1.5". Thats about as good as I can do with any rifle.
