Last highpower match: Sighters are useless on reduced course (wind not an issue). If it ain't shootin straight beforehand, it won't on match day. When shooting offhand, take your time, get plenty of rest and breathing spaces between shots. Don't hurry into position so quickly that you ignore your body alignment, even in rapid fire.
Last IDPA: Test your reloads BEFORE the qualifier, not DURING GRRRRR
I'm switching to FMJ for the next match. That leading adds up during a 90rd qualifier.
