Hey guys, new member here. Im going on my first safari in may 2025 and Im trying to decide the best 2 rifle options I should take on the hunt. I will be hunting Cape buffalo and PG. (giraffe, zebra, impala, and wildebeest). I am leaning towards my lefty Blaser R8 in 300 Weahterby for the plains game? If thats a good option, what grain weight would be a good all around choice? As far as Cape buffalo goes, I haven't bought a rifle yet. Im looking at the 375 Ruger simply because they make in a Left Hand model. But Im open to other options on either rifle. I have been searching the site all morning and just haven't found the results Ive been looking for. Thank you for any advise!
Bullet weight for the .300
In the old days of cup & core bullets that generally fragmented to pieces, 200 gr was the overwhelming choice for .30 calibers, typically .30-06 and .300.
When the Nosler Partition initiated the era of Premium Bullets, a lot of folks progressively went, rightfully in my opinion, down to 180 gr, which insured that the rear core penetrated deep with typically 60% of the original weight, i.e. ~100 gr.
With Super Premium Bullets that retain 95% weight, it makes a whole lot of sense, in my opinion, and in Barnes' litterature, to go down one more step in weight, and some go down two steps. But by force of habit I expect that it will take a couple decades before this becomes standard thinking (just like some folks still shoot 200 gr from their .300)...
I am having flawless performance in my R8 .300 Wby barrel with 165 gr TTSX Weatherby factory loads (gold box) on any PG, including the large ones (Wildebeest, Hartebeest, Sable, Roan, Kudu, etc.), up to but excluding the Eland, which is in a class by himself, and for which the .375 H&H makes a lot of sense. Everyone who started following the seemingly slow but endless trot of a wounded Eland will vocally agree...
Sadly, Weatherby have discontinued the load, and I am happy that I bought 10 boxes (and should have bought 20) when I ordered, it will keep me stocked for a number of years as I only shoot them on game, and I shoot the 165 gr Interlock load (silver box) as a practice load.
When I spoke with Weatherby's technical staff to ask why the load was discontinued, they entirely agreed with the above logic but stated that the demand for a 180 gr TTSX load far exceeds the demand for a 165 gr TTSX load, hence this is what they offer now.
Too bad in my view as all the 180 gr TTSX brings to the party compared to the 165 gr TTSX load, is additional recoil. Both will punch in and out of any PG with a behind-the-shoulder-double-lung shot, which remains the deadliest shot there is, even in Africa: no mammal will go far with two collapsed lungs and likely an exploded heart...
But for those who prefer a shot through the shoulder bones, by force of old African habit, with the risk of causing only mechanical bone and muscle damages far less deadly than vital organs damages, the 180 gr TTSX is probably a more reassuring choice...
In summary, if you shoot factory ammo, the obvious, and entirely logical choice, if not in most cases the only choice, is 180 gr. No need to go heavier.
If you reload, I recommend 165 gr. TTSX.
.375 rifle
As to the .375 rifle question it seems so obvious to me that the "only" logical response is to get a .375 H&H barrel for your R8 (as others have suggested), that I am not sure what would cause you to hesitate. As the old saying goes, "beware the one-rifle-man, he probably knows how to use it...".
Even the financial argument lacks weight in my view: a standard profile .375 H&H R8 barrel costs $1,600, only $400 more than a Ruger .375 rifle, and the advantages of the R8 barrel, as well as the advantage of shooting the "standard" .375 H&H ammo, are well worth the modest price difference in my view.
Practice
To expand on the one-rifle-man concept, the R8 ultimately gives you the opportunity to even practice with that same rifle. Many of us have added a .22 LR and / or a .223 barrel to their Blaser battery for precisely this reason, and to the best of my knowledge there is unanimity amongst those who did, to vouch that this was the right move.
In the future
Actually, if you become fond of hunting the Karoo (or any other mountain), adding in time a .257 Wby barrel will make immense sense for Mountain Game (MG) such as Vaal Rhebok, Mountain Reedbuck, Klipspringer, etc. not to mention any and all small and medium plains game.
The same logic goes the other way: a .458 Lott barrel will make your R8 a DG killer.
In the end, for a traveling hunter, it is difficult to beat the R8 logic of 3 calibers & scopes in an airline compliant <62" linear and <50 lbs Pelican 1700.
MG, PG & Lion or Eland: .257 Wby, .300 Wby and .375 H&H.
MG, PG & Buff, Elephant or Hippo on land: .257 Wby, .300 Wby and .458 Lott.
PG, Eland, DG: .300 Wby, .375 H&H and .458 Lott.
One short and light Pelican 1700 case with three R8 calibers amongst .257 Wby, .300 Wby, .375 H&H and .458 Lott depending on what is on the program of the safari. The perfect solution for me...
