180 partition @ 2970
168 TTSX @ 3150
Both shoot the same 3/4 - 1 moa.
Anyone shot elk with both ?
I’m having a hard time not using the tried and true Partition.

I've shot a number of bull elk with the 180 NP in both the 30-06 and 300 WSM.

I've only taken one bull with a 165 TSX from the 30-06. Worked great.

However, I've had various mono's not open up, including the original .308-165 X, a .308-150 TTSX, and .308-180 Failsafe.

For me, the 300's are all about 180 gr+ bullets, and I'd say in general the shrapnel effect of the Partition will generally put game down faster than a TTSX. However, I'd not be worried about using either the TTSX or NP, even though I don't use mono's anymore.

Generally I used 64.0 of H4350 for 2,980 fps, but later switched to 64.5 of RL17 for 3,030 fps and slightly better accuracy.

The choice for me would be between the 180gr NPT, or the 180gr NBT at 3k.

For me, the NBT would win. It's and Elk Slayer.

Noticeable enough that I should consider RL17?

65g of H4350 is a solid load in my gun with 165 SGK, but average with 165 TSX....

I could try the 180 NP with H4350, or try the '17 with the pile of 165 TSX sitting here.

decisions decisions.

Both my loads were with Re17.
180 Part with 63.5 gr Re17 @ 2970.
168 TTSX with 65.5 Re 17 @ 3150
H4350 shot like crap with all 4 bullets I tried. Go figure.

That’s a very light load of RL17... you could easily go over 65.0 gr’s...

I tried 64 and 64.5 . Accuracy was not as good as 63.5 , and was starting to see some pressures signs with Norma brass @ 64.5 .
I figured 2970 FPS with a 180 would be good enough.

3k is the sweet spot, and the elk won't notice the missing 30 fps.

You must still be learning. H4350 shot lights out in every 300WSM I've tried it in. This was with 165's, and 180gr partitions. I agree with Brad on this. It's a great powder in everything I've tried it in, not just the 300WSM. As for bullets, I've used the 180 partiton on elk and caught 2, without a pass thru. I'd be more inclined to try a 200gr. partition in the 300wsm next time, as I know that is a damn good penetrator, and elk killer in the 30-06, even at moderate speeds.

Yes I am still learning , and I hope you are to.
However I’ve been reloading for 30 + years.
You haven’t tried mine.
I did shoot several 200 partitions. Accuracy was good . 2800 FPS was about max with 62.3 grs RL17.

When I had a 300wsm it was during the great powder shortage..😭 I ended up using h4831 with 190's and 200's.. I was getting 2790 with 190's and 200's. Then I triedcRL19 with 168ttsx and that was a very good load. When I had h4350 it shot very well, but ran out during those trying times had to substitute other powders and make things work. Anyhow to the op buy some h4350 and RL19. My buddy has killed 2-3 Brn bears, couple moose, caribou, black bear with his 300 wsm using my load I worked up using 190 hornady s good luck finding them. Also 180 NAB shot extremely well for me, the 200 NAB shot even better with h4831. But that was during the time you could not find NAB anything. Damn those were trying times..

Apparently 2,970 is the "sweet spot."

Having had 6 or 7 300 WSM's I can verify, like every other rifle, they're all individuals.

I’d use either one. Whichever shot the best for you at your max range would be my choice. The 180 Partitions are a standard, but the 168 TTSX is another that seems to be doing great as well for a lot of hunters. One of my buddies uses the 168 TTSX in his 06 and 300 Wby and wouldn’t dream of using much else.

This is not uncommon. I had used Norma brass exclusively in my 300 WSM's & 7 Wby's. When I began load work for my 300 WSM custom built rifle it immediately showed pressure signs even with low level fireforming rounds. After speaking to the builder, he asked what brass I had chosen. When I told him Norma, he chuckled & told me to switch brands of brass. I did & the pressure problem disappeared. He said Norma was notorious for pressure troubles. Would not have believed it had I not seen it. I was pretty endeared to Norma brass. Still like it & use it, except in that rifle.

Thanks for the heads-up on the Norma .300WSM brass, I was just about to order some from Midway and waste my money 👎🏿.......Hb

This batch of Norma is on its 5th loading and the primer pockets are still good and tight.
Also a 180 gr bullet at 2970 10’ from the muzzle @ 30 degrees isn’t to shabby.

You never know at what angle a shot at an elk may be presented.. You might get a classic broad side like you see in all the magazines. More likely to get a sharply angle shot coming toward you or angling away. You could also get a straight away shot. Consider you have been hunting for some days & have seen nothing.. You are dead tired, discouraged & ready to leave. Then a legal animal is sighted. It's moving almost straight away from you. No time to waste you have to place your shot.. . Maximum penetration is needed. The bullet has to angle from at least the last rib & at last a good 2' forward possibly thru heavy bone. . Me I want the toughest most dependable weight retaining bullet I can get. That bullet is one of the mono.'s . Barnes, Hornqady or Nosler. Which ever one shoots best in your rifle. The deepest penetrating bullets are a one piece homogeneous solid. . A bullet like the Barnes is a homogeneous one piece solid of copper alloy with an expanding nose which tend to retrain 95 to 100% of their weight. The mono's are know for their increadable penetration. . Any bullet that comprises of a jacket of any kind & a lead core of any kind can loose at least 1/3 of their weight & usually much more in the first 3 to 4" of penetration. . What bullet do you want the success of your hunt to depend on. Think about it.

Agreed, and you never know when you might have to take a " Texas heart shot" on a big Whitetail buck you been hunting all year and you'll probly never see again 👍........Hb

Depending on your setup, you could turn a 225gr. ELDM into a cruise missile. What’s lost in initial velocity would be offset at extended ranges by a .391 G7 BC. The payback is retained energy.

The Partition is never a bad choice, but neither is the TSX.................personal preference.

The 165/180 Accubond works just fine too.

I'd take whichever is the most accurate & not give it another thought....................overthinking just fu^cks with the mind; all will kill any elk alive.

I understand. I have three 300 WSM's. The Norma works fine in the other two. Weird, but true.

I killed my bull elk with a 300 wsm with a load made up of 165 gr ttsx, 66.5 gr Rl 17, win mag primer, 3165 fps.

I feel like the odd one out....

180gr Speer Hot-Cor over IMR4831 lit off by a mag primer.

I don't know why... that Hot-Cor bullet can just fly so much better than anything I have tried.

I use the Norma Brass in my 300 WSM and it hasn't given me any problems.

My Loads are 180 TBT @ 2950 and a 212 ELDX at about 2850. The brass has been loaded about 5 times.

Model 70 FWT

I have some Norma brass, 175 lrx bullets and just trying to choose powder. Have not found any load data for h4350 which I have along with Ramshot Big Game and R15. Or should I buy r17? Decisions decisions.

I took my Sako A7S 300wsm to South Africa and killed a Blue Wildebeest, Warthog, Impala, White Blesbok and Copper Springbok with 150TTSX’s. All 1 shot kills except the Wildebeest. I shot it quartering hard towards and we immediately went after it. It laid down 30yds away and when we walked up on it he stood up drunk and staggering so i put another round in him. Loaded 150 Accubonds and 150 TTSX’s with the same recipe straight out the Nosler book with amazing accuracy. 59.5 grains of RL-15, Nosler brass and WLRM primers. Both loads produced 5 shot jagged holes at 100yds. This load should work great on elk sized game.
