I was hoping to shoot the two qual's this weekend with some friends. Could anyone clarify some of the instructions?

I don't have an ACSO 99 silhouette, so I was just gonna use an IPSC target and make the A = 5 points and the C = 4 points.

On stage 1 it says "Kneeling right hand using barricade support". Do they mean freestyle, bracing against the barricade a la Bianchi Cup? Or SHO/WHO using barricade support?

On stage 3 it says "Standing right hand only, Mandatory reload from the slide lock position". Is this a 1 handed reload, or two handed? Thanks.
