Had a 30/06 for almost 20 years that drive 150gr Partitions into little bitty clusters at 300 yards. It didn't matter if the tube was cold or you could fry an egg on it, all right in there.
Oh yea, jump was .25", yep 1/4". No telling, one just has to play.
Bumping this old thread since I consulted it when starting on a 180gr partition load for my husqvarna .30-06.
Started at 0.030” from lands. Results were ok but not great. Then I shot some old factory federal rounds with the same bullet. Slower than hell, but right at 1 MOA, which is better than I was getting. Measured a few and they were about 0.12” off the lands in my rifle. I said what the hell and loaded up a few to that length with my previous best charge…first group was 3/4”. Glad I tried those old rounds!
