Reg Leg, to take a 250 m shot with a double for a Kudu or Oryx... yes, good luck and I can not be comparable to you...... I stay within 80 m and have done it for long time !
So, when you have experience enough I would be interested.
So why don't you read what I wrote - As for experience, I have made the profession of arms my whole life. I have been in combat more than once to include special ops. I could be equally derisive of your vast expertise with weapons. I have no doubt you have more double experience on game. So let's both can all that bravado and try to objectively look at what I actually said.
1) The right and left barrels of the S2 shoot TSX bullets into separate minute of angle groups. Those two groups form a 2 1/4 inch non-crossing composite group at 100 yards. I use a Zeiss Victory and sight the rifle in so that the right barrel is one inch high at 100 yards. I have no hesitation taking a right barrel shot out to 250 meters with the rifle with the scope in place. I admit I have done that on game only once with the .375 (waterbuck), but several times with the 30-06 barrels in place.
2) At 250 yards the above regulation gives me about a 5 inch composite group. Is the second, instantly available shot as accurate as the first at that range? Of course not - but it is minute of kudu or oryx if I need that immediate follow up.
3) That said, with the .375 barrels in place, I am not principally hunting plains game. In this case, in August, I will be hunting a buffalo. I will shoot him with the scope in place just as I would with one of my mausers. The only difference is that I can hit him with a second round far more quickly. Is there an advantage to that? I don't know, but I would think it would be just as advantageous if I were squinting over the open sights of my .500/450 at 60 yards. But unlike the .500/450, I do not have to have a second rifle along to deal with a target of opportunity should it appear.
Should a rifle like the S2 or my use of it offend you in some way as non-traditional, I really am not likely to lose a lot of sleep over it. That strikes me as your problem - not mine. The weapon works exactly as I have described it. Perhaps you should give one a try before you deride my experiences. And should we want to compare total round count down range and under what conditions than let's do that off line. You can PM me. I am sure that I'll be impressed. You might be surprised as well.
