Home Forums Reloading Big Game Rifles 300 win mag 180 vs. 200 and 220.gr?

Bob: Good post!

Interesting!

I'd take a look at the 212 great Hornady ELD. Fired from a 3006 it has more energy at 400 yards than a 180 gr partition from a 300 mag. It has more energy at 125 yards than a 220 great RN fired from a 300 mag. Aerodynamics matter even at moderate ranges. I can only imagine what it does at 300 mag speeds

I like the NAB/NP 200gr and H1000. A real can of whoop arse! My rifle is 9-1/2 lbs so recoil is not bad.

Nothing personal....I ran these numbers last night on the ballistics calculator,but used a 300 Weatherby with a 180 NPT at 3200 fps against the 30/06 and the 210 VLD at 2700 fps.. Turns out at those velocity levels the 180 NPT beat the 210VLD in just about every category.Like you say the numbers can look close.

Energy figures are swell on paper, but since I've stoned bull elk where they stood out to400- 500 yards with a 180 NPT a few times,and after smashing the onside shoulder at near 500,and recovered what was left of the 180 Partition clear back against the rear ham on the opposite side,folks will have to forgive me if I ignore the paper ballistics.

I could also talk about the Alaskan brownie I saw wither like an empty puppet after he took a 180 NPT through the chest at about 100 yards from a 300 Weatherby.Or another big herd bull I killed that collapsed at 70-80 yards from a 180 NPT from a 300 Win Mag that broke both shoulders.

I've used the 200 gr Partition on game as well from both the 300 Win and Weatherby,as well and it's just more of very much the same thing.

During all these years I never looked at an energy number, kill quotient,or other formula which purports to quantify killing effectiveness,which tend to fall flat on their face in light of bullet performance on animals.

I could go on ad nauseum but I am not going to trade dependable expansion and deep penetration of a Partition (and similar designs) for a thin jacketed C&C bullet just based on its paper ballistics.

Especially since i don't aspire to kill them at much over 600,where i think these high BC specialty bullets come into their own. For that I suspect they are swell....but 1000 yards is beyond my abilities and desire.

I am not much for chasing energy numbers.

Please forgive the rant....

You dig up a thread from nearly 7 years ago and that is your response ??????? that is interesting!

What velocity?

Remfak pretty much nailed it. I all but switched to the 200gr. Nosler partition in my 300wm, but expect more recoil than either the 165 or 180. I ran them at 2,950 fps and it really thumped chit, especially my shoulder...

Is 2950fps what you're also getting from a 24" barrel?

I'd think that any 180 gr bullet at 3050 fps would kill anything that a 200gr bullet would at 2950 fps.

see this is a revived old thread but,

not a big magnum guy... but own a pair of 300 Win Mags..

one bought cheap on an after season sell.. and the other was a trade to someone that just had to have a 22.250 I had...

When I do need a mag, I believe in making it a magnum...

worked this up and it functions fine in my Browning with zero issues... and the brass doesn't seem to mind, as I've loaded some cartridges 10 times with this load...

but 83 grains of H 1000 ( 300 Weatherby Data, 5 grains over 300 WM data).. with a 220 grain Sierra or Hornady round nose...

velocity is just short of 3000 fps...however you'd be surprised on how flat shooting a 220 grain RN can be at that MV....when I hit steel with it at 300 yds, the "Clang" sure gets people's attention....

a 220 grain SMP partition would be my pick for hunting big stuff with it...and actually think it is superior to a 338 Win Mag with a 250 grain Bullet...

but without the extensive experience others here can bring to the table... its just that, my opinion...but then again, I'm the one carrying my rifle...

My .300 WM likes 180 NBT's and NAB's, over RL-22 with Fed 215 primers.

The NBT's are slightly more accurate, both have the same POI, same B.C.'s and same ballistic performance in general.

I choose the bullet depending on critter being hunted, desired termainal performance.

I generally agree. This said, I'd somehow prefer to have a 200 gr. NorthFork over a 180 gr. Accubomb if hunting Grizzly

Well.....yeah. I mean construction varies.

I agree with you 100%

I have seen and ran a couple of 300's for elk and muleys. Most of them have ran 180 PTs. Lately the shift has occurred towards the 200 PT and ABs. Can't see much detriment to it, and the heavier 200 PT seems a little more robust than the 180 version, but me and friends would have to take another 100 animals to really tell the difference I'd bet.

200 grain Partition in a 300 Win. Mag. I would say is a heck of a load. The 200 grain Partition is a real digger. I'm sure a guy could hunt any North-American animals with that combo. Pair it up with a nice .308 Win. That would be pretty nice.

I like the 165 Barnes in my 300 Win mag! Kills deer-pigs-Aoudads dead!!!

I would think that a 200 or heavier bullet run at maximum velocity would be a handful as far as recoil goes and would not kill any deader than a similarly loaded 180 gr. bullet. I have harvested lots of deer with 180 gr. bullets all one shot kills so I am satisfied with the 180 gr. and in some instances have gone to the 165 gr..

I have a Remington 700 5R heavy-barreled .300 Winchester Magnum. It shoots quite accurately with several bullets, but these have all been 150-180 grains. In the last couple of weeks, I've done some preliminary work with the 200 grain Sierra GK and H4831SC powder. While I've struggled to get a muzzle velocity of 2800 fps, it appears that this bullet may be the most accurate hunting bullet tried so far. This is one of the few bullets I've ever used where seating depth made virtually no difference in accuracy.

Again, I've only done limited work, but it looks promising so far.
