My manual of arms with the Blaser R8...
I do it just a bit different, but in an identical way regarding the safety aspect.
I carry the rifle with full magazine and empty chamber until I get in "approach" mode, which can be either the final 25 yards of a PG stalk; or when the spoor gets so fresh that DG can be closed in at any time; or on the follow-up of an animal that was shot and did not drop on the spot.
Client PG or DG hunting is not quail hunting, or PAC work, and the chance for flushing unexpectedly at 10 yards an animal that I could and would want to reflex-shoot without judging it first, is so remote that I am not overly concerned about it.
The final 25 yards of a stalk, or very fresh spoor, justify a loaded chamber and a decocked R8, until the rifle goes on the sticks. And, of course, the follow-up of wounded game requires a loaded chamber, and I would go as far as saying that it likely justifies a cocked R8 when wounded DG is in open sight at bayonet range.
I typically load a round from my belt directly in the R8 chamber, on top of the loaded magazine. Since the R8 does not have a CRF extractor, it does not damage the extractor, and although I do not expect to use 3, or 4, or 5 shots, I see no reason to use the rifle at less than full capacity. And it is a rare case indeed, when I do not have plenty of time to load this way.
I automatically/mechanically reload, during recoil, after each shot, regardless of what I shoot, from Duiker to Elephant.
I systematically unload (remove the cartridge from the chamber) when the approach/follow-up action is over. This can be after a successful approach and shot(s), or this can be after a failed approach, or after a successful approach and a decision not to shoot, etc. Depending on what just happened, I put the cartridge back on my belt if appropriate, or I top the magazine if needed, and I close the bolt on an empty chamber ... and dry fire.
I happily admit that dry firing on an empty chamber is wholly unnecessary with the R8 since I need to cock the action to do it, then decock it after doing it, but for 40 years the "click" has been the final step in triple checking that the rifle is inert, and I still find comfort in it. Leopards do not shed their spots, I guess. Besides, since I invite the PH to listen to the click, it is also for HIS comfort...
I always verify that I have an empty chamber before packing the rifle and boarding the truck, even if I KNOW that I have an empty chamber. Since accidental / negligent discharges mostly happen with firearms that people "KNOW" are unloaded, I guess that knowing is just not enough...
Yes, the R8 is mechanically inert when decocked, and therefore safe, but I still like an empty chamber. Unless in "approach" mode (which includes follow-up), I cannot think of a single reason to carry a cartridge in the chamber, and I can think of a number of scenarios where it could become a liability. For example, on my last Vaal Rhebok hunt, the farmer/rancher whose mountain we were hunting, and who came along to guide, felt free to manipulate my rifle, without asking permission, while I put it down to take a layer off. I was happy that he did it on an empty chamber...
We all are the product of our own experience, and part of my experience is to have helped a South African friend NOT commit suicide after his rifle accidentally killed a woman because a cartridge was in the chamber when everyone thought that the chamber was empty. Of course a long list of firearm safe-handling mistakes were made all along, from the accidental loading of the chamber to the unintended touching of the trigger, but this is not the point; the bottom line point is that empty chambers cannot fire, no matter what...
As to removing the firing/magazine group to decock, I do not do that because I lock the magazine in place before top loading it, to avoid the risk of accidentally loosing it...
