I am interested in taking my AR to practical rifle at tri-county, but I can't seem to find much information about it. I haven't done any practical long-gun competitions before, but I've been shooting IPSC/USPSA for the past 6 months. Who should I get in touch with? Is there any safety training I have to do beforehand or is it enough that I do IPSC? How much ammo should I bring? Any other tips or suggestions? Also, if anyone knows of any 2-gun competitions around Oregon, I would definitely be interested in that as well. Thanks!
