Training for gas gun matches, what target sizes?

Just me but when I got into the prs type matches . I just took my camera , a note book , and ask probably a hundred questions . Thats where I would start. Plus you can get a chance to see what the format is like . where I shoot we don't shoot any further than 700 yds with gas gun's . If all else fails contact the match director , I have yet to see one who won't go out of their way to help somebody wanting to get into the game .
 
I’ve shot a lot of PRS/NRL matches since 2017 so in general I know what to expect match wise.

Always liked gas guns and just want to stay practiced up for a gas gun match if I find one that works out for my schedule next year.
