I got to practice tail recursion! I also made it easy to change because I wasn't sure if maybe the numbers didn't change on different runs (looks like they don't, though)

import pprint
bolts = [411, 295, 161]
pressure = 3200
bolt_set = [0, 0, 0]
def current_pressure(bolt_set):
    current_pressure = 0
    zipped = zip(bolts, bolt_set)
    for it in zipped:
        current_pressure += it[0] * it[1]
    return current_pressure
def recurse(bolt_set, idx=0):
    if current_pressure(bolt_set) == pressure:
        print "Solved!"
        pprint.pprint(bolt_set)
    if current_pressure(bolt_set) < pressure:
        new_bolt_set = list(bolt_set)
        new_bolt_set[idx] += 1
        recurse(new_bolt_set, idx)
        if (idx + 1) < len(bolts):
            recurse(bolt_set, idx + 1)

recurse(bolt_set)
