Home Forums Hunting & Shooting Express Rifles and Big Bores Only 300 vs 350 gr 416 TSX for buffalo/ DG

Seems some of the 375 crowd is recommending the 270 TSX (or TTSX) for buffalo over the 300 grain. Does anyone have knowledge or experience (well-founded opinions might be OK also) on the success of 300 TSX vs the 350 TSX on buffalo/DG. Sectional density is something we don't talk much about anymore with monolithic bullets and the shorter 300 (1.2+ inches, s.d. .242) compared to the 350 (1.4+ inches; s.d. .289) are significantly different. By reference the 270 gr TSX is 1.3+ inches and s.d. of .272. I suspect any of the TSX would be fine for large bear, but what about thick-skinned? I am not looking for effective in best case scenario, but good in the chamber for less than ideal as well which means a charge to me.

The 300 TSX can be driven to near 3000 FPS in the 416 Rem I’d think it would be effective on Buffalo

JMO. I’m “not” a fan of light Bullets....even with “mono’s”! If I were going after “buff”, with my .375. I certainly wouldn’t go lighter than a 350 in a .416. In that ball game, weight and penetration trumps speed and flatter trajectories! memtb

No experience with the 0.416", but have used the 0.423" bullet in a 404 on several animals including buffalo. I prefer the heavier bullet (400 grain) at 2400 fps.

More penetration, especially in the worst case scenario you describe, is a characteristic of the heavier bullet and a definite asset. More velocity in an expanding bullet, given equivalent construction, is more likely to result in less penetration.

Never used em on heavy game, but 350gr TSX all day everyday, it wont be long range shooting.

I imagine a 300, 350 or 400gr would work out of 416. I would personally lean towards the 350 as extra speed never hurts a TSX, and it would flatten trajectory out if you needed to stretch it for PG. Dedicated buffalo hunt, a 400gr would be my choice.

My 400gr .423 worked fine last year on my buffalo, right at 2200 fps and the shot was a whole 40 meters long.

The 350/416 is well proven on buffalo. I plan on using it on this years trip for buff. I've used them on eland before.

Either will give enough penetration on a buff but my choice is the 350. Let someone else gamble their trophy fee!

The 350 gr TSX worked (416 Rem) like a champ on my Zim buffalo. I see zero reason to go lighter.

I believe I remember reading back in the day where Ross Seyfried completed a whole safari with 350gr TSX's and a 416, buffalo included, iirc, he came home and shot a bull elk at a hundred and some yards in a wallow too.

Read this with interest as I am hunting buffalo in Zim next month with my son and daughter and her favorite load for all Alaskan game with her 416 has been the 300 TSX . I was thinking of loading up some 350's. Maybe she can load a 400 gr solid down, followed by a 350, with the 300 on top and we can see how they work.

My son is taking his 375 No 1 Ruger with 270 TSX and I will have my 458.
It should be fun and Phillip Smythe will be backing us with his 500 so all should go as planned

I assume she has used the 300 TSX on moose, in my mind if it performed well on moose it will do the same on Cape Buffalo. I expect it to work well.

She uses it on everything, including Dall sheep

I like her hunting rifle decisions......find one cartridge, one bullet that you like, and use it for everything! memtb

I hunted a handful of plains game on the same trip. The 416 was my only rifle and did fine on a decent kudu at 250 yards and others well over 100 yards. My buffalo was taken at 110 yards.

She is ultimate familiar with the load so I’d change nothing

NICE! I love simple effectiveness.

I spoke with Connie Brooks years ago on both the 375 and 416. In both instances, she reiterated the 270 in the 375 and the 350 in the 416 appeared to perform better on Buffalo. Yeats later, Ross Seyfried in his book was adamant that NOTHING killed buffalo better than the 350 TSX...out of a 416 Weatherby.

NICE! Thanks Jorge, I couldn't remember which 416 Ross was shooting.

Because people read RAGS!!>> Why do people want the 375 shoot like the 3006, why do people want the 416 to shoot like the 375 , why do the people want the 458 to shoot like the 416!?!?! People read toooooo many RAGS!! Enjoy

Please expound on your actual African experience using above mentioned calibers, cartridges and bullets.
