[Marvel] how good would Hawkeye be with an unreliable device, say a cheap and inaccurate slingshot?

As per title, follow up question: if he were accurate with it, would he need to fire it once to get a 'feel' for it or could he get all the info he'd need for accuracy by simply looking at the weapon?

What hawkeye

Clint of three worlds

MU - Held be good a human level crack shot he'd need to get a feel but that not gonna take long it only take a few throws of cap's shield to be as almost good as steve at throwing it. 

MCU - It's not superhuman but his Line about golf, gives you a level of skill that almost superhuman. he may need on practice swing

Ultimate MU, Clint is superhuman and has bullseye's powers in one story killing men with flicked finger nails while tied down, any item in his hands is deadly. with no practice time. 

old man Hawkeye - is doing zen archery while blind and has even more experience than MU Hawkeye

Kate bishop - Hawkeye
Kate is almost as good as Clint but needs to take longer training and it clear with time she is gonna be even more skilled than he is (faction Run)
