One hole shooter
It is nice see someone else has done some work with this cartridge. I did this back in 87 and made a true one hole shooter. On a saturday morning in still air, I put the first four rounds through the same hole. The fifth was a bad trigger, and I knew it as soon as the gun went off. ihad pulled it to the left(Left handed) about half the diameter of the 308 bullet. I am not healthy enough now to keep that type of shooting up, so I am putting it up for sale. I still have that target, but over the years the hole has become larger. I used a 35 degree shoulder and fire-formed the brass. Once formed I would turn the case neck and seat the bullet so it engaged the lands. 125 gr spun hollow point custom bullets, and a 26" barrel (Heavy).
