Just for fun, here's a 100 yard target I shot a while back while working up a load for my .243 using a new powder.
I started at the top left, then shot top right, then bottom right, and since it was the last load (max load), I shot the center last. At max load I lost the fliers, and I've double checked that several times since.
Touching bullets at 100 yards with a rifle made in 1956 (a year after the .243 was introduced) is pretty decent in my book. The chrony showed this load to be shooting between 3030 and 3040 fps, so the consistency is incredible; even moreso when you consider that this load is with IMR7828SSC, which isn't even supposed to work well in this cartridge. No signs of excessive pressure at max load in my rifle.
