lgm, point taken, especially for african plain game rifles, and even DGRs . I agree that a hunter must master the recoil of his/her gun. Here I'm referring to .416 and up DGRs. However, I've heard and/or read instances where a client makes rapid multiple follow-up shots with a .458 with blood oozing his nose. Perhaps that client should not use a .458, or he should not make follow-up shots (let the PH do it, hehee).
In my original post, I'm just curious to know if a PH would allow a client to use a muzzlebrake, provided of course the client provides a Game Ear (hearing protection/enhancer gadget) for each one in the hunting party (PH, tracker/guide). That gadget (worth around $150 each) of course will then serve as a gift to each one.
This past weekend I practiced shooting my .416 Rem all morning (40 rounds during a 4 hour window) shooting off hand alternately with and without muzzlebrake, and shooting at a 50 yard target followed by a QUICK 25 yard shot (simulating a DG charge). In between these two rapid-shot sessions with the real rifle, I also practiced the same with my 9 lb. PCP air rifle (.22 with a 30gr pellet at 800 fps). The real rifle is a 9 lb. Blaser Luxus R93 Safari rifle with the included 600-gram tungsten filled tube/recoil-reducer inside the buttstock to balance the weight of the heavier barrel.
I can shoot the .416 Remington offhand all day (in regular intervals), not bothered so much by the recoil or blast. The issue is the time it takes to aim for the must-do quick followup shot, and the quality of the shot. Having that muzzlebrake on makes a LOT of difference - in the time and precision of the followup shot, as attested by the group sizes in the 25 yard target. Of course, the ibest result comes from the 22 air rifle's performance.
