Ive had surprising good luck with the 3P EZ and the 250gr GoldDot in a few guns...even if they loaded a bit loose. The 300gr i had the best luck with the HPH-24 and heavier charges.

If you have a micrometer, check the size of the 250s. Lately they seem to run a bit on the large side but the 300gr seems to be right on the money or very close.
