Then go get someone to help you with the finer points and correct any minor errors.
And bring that peashooter out to the next Speed Steel shoot at Mission. Low key fun and you'll get lots of practice with instant feedback. Not to mention no lack of opinions....

But seriously we have a couple of pretty good shooters there that know how to coach well. A combo that doesn't always match up. These meets are about fun and skill improvement for folks at ANY level so as bad as you may be or think you are do not feel that you're not ready for a Speed Steel match. These matches are very raw newbie to expert friendly. Just let someone know early on that you're looking for pointers and the organizer will match you up with a suitable mentor for the day.
