I shoot IHMSA often. Not as often as I would like...
I am shooting UAS with a XP-100 in 6.5 BR for full scale and 22 BR for half scale. Both are rear grip guns that have Lilja barrels, Anschutz triggers, and Leupold scopes.
Of any of the games I play, it is the most relaxing. Just lay down and start shooting. The time constraints are not real tight for me being an IPSC shooter at heart.
Now that our Sniper Matches and Steel Challenge Matches are over for the year, time to start up IHMSA again.
