I can tell you that as of yesterday I was shooting the tightest groups that I have ever shot at 500 yards using the New A1 tips. This was using a pre 1992 Browning Bar type model made from 68 to 92. I think everyone should try these bullets and see for yourself. And you are correct they have ran a limited production before of the same type. Guys I'm not kidding these babies shot great precision. Actually it was the best precision that I have shot with this rifle. I'm going to try 800 yards just for the heck of it due to what they did at 500 yards. Then I think I am going to try them in my other rifles. Or at least purchase a good quantity of them for each caliber before they are sold out.
