Re: 308 A.I. at almost 2 miles?
Thanks for that awesome post! The link on the group was very interesting. I guess if you fired 1000 shots at a target it would have to be perserverance.
That mini palma sounds tough. It would be fun to watch for sure.
The story of the 22-250 fast twist started last year. A friend and I were out at my mile range shooting at the gong at 1000 yards. The 75 grain A-max were hitting the 15" piece of steel almost too easily, so we decided to put the gong out at 1200 yards. We each nailed it several times and soon got bored again, so we moved it out to 1400. I shot first and I couldn't see where I hit. I fired 10 more shots and nothing. Not one puff of dust anywhere. So I grabbed the walkie-talkie and drove downrange and stood behind a telephone pole off to the side and about 200 yards from the gong. This was out in the desert in a spot that has no grass or sagebrush, so it is easy to spot a shot. And it was particularly dry this day. From my hiding spot, I told my buddy to start shooting and what I heard was amazing. I could hear the bullet coming a ways behind me and then as it went past, it made a very weird zingzingzingzing sound. I broadly looked out into the field and there was absolutely no bullet or bullet fragment hitting the ground anywhere! He shot several more shots, and all had the same sound and result.
The next day, I was on the phone with the Sierra tech boys and they said that the bullet probably yawed itself into oblivion. I guess when a bullet begins to yaw from transonic flight, it exposes more surface area directly to air friction which can be quite hot and a thin jacketed bullet basically incinerates itself!
Since then, I have done some testing of larger, less radical designed bullets with thicker jackets at subsonic speeds. I have found 308 with 180 bullets go subsonic before getting to 1000 yards, but they still plopped onto the backstop. They had absolutely no accuracy, as none of them came close to hitting the gong even in calm conditions. But I need to test this same gun/bullet combo at 1500 or maybe a mile to see if it ever starts to wobble enough to cook itself into pieces. It might not being such a big chunk of material.
I have owned that book for about 3 years. I had read the articles in question even before buying the book and the book made me question it even more! Anyone can take pictures of wild equipment and a shooting outing, but that doesn't mean it actually worked. The book's chapter is written by a witness and not by the actual shooters. The author can fib (not saying he is) and it would not count as them actually being the ones who fibbed (not saying they are). It would have been more believable to have the shooters also be the authors, then if there was a fib, it would be on their reputation, not an innocent witness!
If it's not far, it's boring.
