    I ran into the same thing with my 22-250. I eventually saw that every caliber in existence is the same. I worked my way up to the max of the maxes. It made more noise. It had way more blast. Even my sister commented on the difference. But in the end, the max-max loads shot like "crap" If I'm used to seeing 1/2 to 3/4 groups, 1.25 groups don't really cut it. I'll take a loss of 150 fps (I'm guessing, I don't have a chrony) to gain that half inch back. What good is missing a varmint at 400 yards even if you have the fastest load available for your gun?

    And those max loads were clearly hard on the brass as well.

    Shoot them only for amusement. It seems everyone here has a similar opinion to mine. More noise, more blast, less reloading (from cartridge failures), and less accuracy.

    You'll probably find the mid-range loads are the most accurate. Though the low-level loads are nice due to being less noisy.
