Bullets too long to fit in a magazine, feed or chamber will fall out of MOST case gauges/ammo checkers (other than full length) all day long...

If you 1st determine what OALs are required with your fire arm(s), then adjust the powder accordingly (if and as needed) your reloads should work.

Longer isn't necessarily "better" in all instances. Loading some longer than usual (for caliber) bullets short (so they'll fit) is where pressure-related problems can occur.
