The ASA websight is
www.asaarchery.com but they have a speed limit of 280 fps in most classes but a 260 fps speed limit for the hunter class.Quess you need to get some serious weight added to your arrows for those kinds of speeds.Do it early so you will learn how to judge yardage because those guys can flat out judge.
Not sure about the IBO web site.Just do a search.There board is on this site.Scroll down in the forum categories. They have a 5 gr /pound rule and if you choose to shoot lighter than that,you have a 280 fps speed limit.You must claim which category before they check you.
