Ive been using partitions for over 35 years love that bullet. Going out on a whim and trying some 200 grain out of my 300H&H for Africa this month. Any tips and pointers using the barnes bullets, having never used them before. All coments greatly appreciated.

Cheers
 
I would try a "lighter" triple shock, with these bullets speed is your friend. A good rule of thumb with these bullets is to move down a weight class as the monometal bullets do work differently. Penetration will still be there is spades.
 
Depending on the twist rate of your rifle, the 200 gr Barnes bullets might be a little long to shoot well. Generally speaking, you should try a bullet lighter than what you usually use when you try the TSX bullets.
 
Your 300 H&H is probably a 10" twist, so will stabilize the 200 TTSX just fine.
However, the suggestion to go to a lighter bullet when using the TTSX is a valid one.

If you have been using the 180 Partition, then you may want to try the 168 TTSX

If the 200 Partition was your poison, then the 180 TTSX may be the best choice.

Remember, when loading the Barnes bullets, most of the TTSX like to jump to the lands. [start at .050"]

I certainly would not worry about taking the tried and proven Partition to Africa, though. :)

If you have to do it, go with significantly lighter TSXs like the 168s and shoot everything through the shoulders. Make sure that you can't budge the seated bullets, it doesn't happen everytime but a lot of brass/die combinations seat these bullets loose.

Honestly though, I'd fight off the whim and go with the Partitions. Its a bit too deep in the creek to be switching horses, and the Partition just might be the killingest thing ever made.
 
that is one long bullet shoved deep inside the case, I am sure the bullet will perform the way it should, just that gut feeling thing, am going to run a bunch through the gun and have the tried and true partitions as a back up if the triple shock does not group as well or shows signs of pressure. Im running a pre 64 Hate taking these things to the last minute
 
One observation from loading many TSX: make sure you have a good inside chamfer.....they tend to want to "hook" as each groove slides into the neck, sometime shearing off a bit of bullet material. Could be just me, but thought I'd mention it.
 
I suggest that you stay with the partitions as well. Maybe try the Accubond if you want to try something new.

Otherwise, the 200 gr TSX in the 300 H&H in my experience is just too long. You lose valuable powder space (unless you have a true magnum action like a 602 and free bore that allows you to seat the bullet way out - then go for it).

I agree that to use a 168 TSX or maybe 180 TSX would be the most I would try. They are still plenty heavy and fast for African game (but for the heavy, thick skinned species).
 
End result good trip. The triple shock performed very well. Bloody long bullet and definitely saw pressure issues in country, but not in my own range. Lesson learned. It's a very accurate bullet more accurate than a partition but the pressure issues make a guy scratch his head as my loads are not cookers.

Great to hear they worked for you.

How far off the lands are you?
 
tight to the lands

With the pre 64 magazine well being so large I was able to put the round right on the lands, and still have room in the mag, undeniably a more accurate bullet than the partition, but at the cost of pressure. I like to use the higher end of the weight spectrum, for the most part everything was a clean one shot and drop, put insurance into the kudu from a close distance on the PHs recommendation to seal the deal, bullet travelled the length of kudu and lodged in his neck rode the spine for awhile then followed the ribs in the arc punched through the meat of the front shoulder clipped the forward shoulder bone deflected and stopped in the neck. I would not be suprised if that bullet does not weigh 180 grains, not had the opportunity to stick it on the scale,

on a side not what else is SCI doing to stop the foolishness of the import of trophies. Most of my clients are just regular working guys and the cost alone of getting things re dipped of which they do not need are starting to slow a lot of my clients down, its adding about %18 to 28% onto there taxidermy bill I am going to be the guinea pig and have most of my hides tanned in country as we are now working in conjuntion with HighVeld Taxidermy

If you actually seated them to the lands, that is your problem, as the Barnes monometal bullets will produce abnormally high pressure, if seated closer than about .030" from the lands. I find that they perform best .040" to .070" from the lands, and I have not run into any pressure issues.
 
If it's not a hot load I'd suspect your pressure problems are a result of being on the lands. I'd back them off 20-30thou or so and I suspect you'll see a difference. I've shot lots of monometals in hot climates without issue.
 
Remington's Model 700 CDL 300 Ultra Mag Part II (make sure you click on the link below and look at the fired bullets recovered)
http://www.realguns.com/archives/164.htm

"Bullet performance at elevated velocity can get a little dicey. The Remington CDL was fairly accurate across the weight range from 125 grains to 200 grains, however, it seemed to become exceptionally accurate from 165 grains up. The best 100 yard groups came from the least expensive and the heaviest bullet. The best 200 yard groups came with Barnes bullets. The best performing bullets, in terms of expanding and holding onto weight at any distance came from Barnes Delrin tipped TTSX bullets. I don't know what they do in treating the alloy they use for their bullets, or what treatment they receive afterward the mechanical production steps, but I have never seen copper this malleable hang together so well when pushed this hard."
 
Must be the seating depth, as when I hunt Africa, I drop my load considerably. I was far from what I would not hesitate to run in -20 which I see more of than +30:) None the less ive got 19 months to get new loads for three other vintage rigs for the next hunt
