Was testing some new to me bullets today, 243 cal. 75g sierra FB HP at 100 yds., When i got to the top of the ladder for near max charge, a 3 shot group had only 1 bullet show up. How can you tell when a bullet disintegrates before it hits a target at 100 yds? Im shooting a Rem 700 with a heavy 26 inch barrel with RE-16, 3 shot groups, 43g, 43.5 and 44g, near max. The 43g group was good at only 3/8 inch, the next of 43.5 was 1 1/2 inch, and then, like I said the third and last group at 44g only 1 bullet on the target, and I know it was'nt me, because my groups that morning were all 3/4 inch or less, and these 2 bullets did not show up anywhere on a 3ftx4ft target. I decided not to use my chrono today, because I had load data for the same load only a different bullet, a Hornady 75g vmax, which I chroned before at 3587fps. Im pretty sure that this one was a bit faster, because I had to seat the bullet .030 deeper in order not to jam the lands on my short throat new Shaw barrel. Any ideas where my other 2 bullets went?
