After my initial South African plains game safari, I quickly found myself captivated by the thrill of African hunting. As an avid collector and user of bolt-action rifles—perhaps even to the point of indulgence—I was eager to add to my collection. My most recent acquisition is a Blaser R8 Professional Success Leather, which I procured through a deal with AH member @BeeMaa. This rifle, equipped with a 375H&H barrel, has proven to be exceptional. I also added two additional barrels—one in .300 Win Mag and another in .257 Weatherby Magnum—both of which demonstrate remarkable accuracy.

As I prefer shooting suppressed, I had Silencer Central thread both the .257 and .300 barrels to accommodate my suppressors. Additionally, I commissioned a custom Gunfoam insert for a Pelican Vault V700 case, specifically designed to hold the three barrels, three scopes, stock, two suppressors, assorted magazine inserts, and extra trigger/mag group, this case weights 43lb fully loaded. This case allows me to conveniently transport everything necessary for hunting, ranging from small deer/antelope to dangerous game.

Since last October, I’ve spent a considerable amount of time on the range, firing more than 500 rounds between the three calibers and stretching the distances out to 600 yards at the CMP range in Alabama. I’ve also put the rifle to good use in the field, taking a few whitetail does, a half dozen wild hogs, and a Saskatchewan black bear. The 375H&H was used for the hogs and bear, while the .300 Win Mag accounted for the whitetail deer.

While I’ve thoroughly enjoyed this rifle and have had great success with it, I did experience three instances where the spent brass failed to eject properly, landing back into the breach and potentially causing a jam. Two of these occurrences took place at the range, and the third occurred during a hog hunt. While this issue is not critical for non dangerous game, I recognize that it could become problematic in the event of a dangerous game encounter, particularly on a buffalo hunt. It is possible that the malfunction was user error, but I take full responsibility for ensuring the rifle I rely on for dangerous game is flawless.

To mitigate this concern, I’ve recently purchased a Winchester Model 70 Alaskan in 375H&H, which will serve as my rifle for testing and further familiarization. I own several Model 70 rifles, and I have full confidence in their ability to reliably extract spent brass. Given my experience with the Model 70, I am confident that this rifle will provide the level of reliability required for a successful dangerous game safari. I will continue to hunt with the R8 just don't trust my life to it.

Have you tried recording ejection in slo motion from an iPhone to see if the casing is bouncing off the scope or turret ? Will a R8 cycle and eject empty brass to test it ?

I'm sure it is bouncing off the scope but it happens so infrequently it would be hard to catch. The scope that is on that rifle is a Leupold VX6 2x12 so it has about as low profile turret as possible. In addition I have it in the high scope mount so the suppressor is not in my field of view so it should have plenty of clearance.
 
That’s a nice set up, @jimbo1972. I never heard of spent brass ejection problems with R8 before. I have shot hundreds, if not thousands of rounds, using various barrels on my R8 rifles without a problem.

I am trying to imagine what might have happened. Do you recall whether you pulled the bolt too slowly or not enough force in those 3 instances?

I tend to be rather forceful when operating any bolt action as this is something my dad taught me is not mess around unless just unloading. First time it happened I dismissed it but since it has happened twice more something in the rifle shooter system is not 100% reliable. Like I said it maybe me but I don’t have the confidence I do with a controlled feed action in a dangerous situation.
 
I've only owned two 375H&H barrels. One was on my wife's rifle (Selous barrel) and was sold to @Challer. The other one is a 17mm standard barrel with sights that I still have.

To my knowledge, I've not sold anything to @jimbo1972. However I will concede that I'm an unabashed proponent of the Blaser R8 and wouldn't be surprised if I had assisted in your purchase. I've done so for many of the members.

You have quite the setup when it comes to the R8. If I were to buy another barrel, it would be the 257WBY and we'd have nearly identical rigs. Congratulations.

FYI - I've fired hundreds of rounds through my 375H&H and never had an ejecting case hit the the turret and fall back into the chamber. You should have this further investigated and either make alterations to your setup or adjust/repair the extractor. There is no sense in having a DG capable cartridge on a rifle and not be able to use it for that purpose.
 
I am curious, which barrel(s) has this happened with and are you using the same type of mount and size and scope on each barrel.
 
I apologize I bought i

I apologize I bought it from @Bwaybuilder not Beemaa. I guess I have read so much good information from Beemaa I got the two confused.
 
I would try one of your other scope mount setups on the .375H&H to test first. I’ve never had an extraction nor ejection problem with my R8’s. I was out shooting my R8 .375 H&H yesterday. I use a Z8i 1-8x24 mounted to a standard Blaser rail mount on the .375H&H. I don’t recall ever noticing the iron sights. I live in California where Sound Supressors are prohibited, so I have no experiance with them nor High mounts.

Hi Lance, Hope you well. I collect Mauser rifles and they are very much part of my cultural history in Africa. Would you consider selling the rifle now a year on ? I'd like to place it in my collection of Mauser rifles. Many thx

I saw where you hunted elephant with backcountry safaris in Zimbabwe.
Was looking to book an elephant hunt and wanted to know how your hunt went
and if you would recommend them.

Thanks
Mike
hi, do you know about lions hunters, leopard hunters, and crocodiles hunters of years 1930s-1950s
I'm new to Africa Hunting. I would like to purchase a Heym 450-400 double rifle. I'm left-handed but would prefer a non-canted gun. Is anyone in the community considering parting with theirs?
