Pointed (Spitzer) Bullets and Cross-Winds

Let's assume that you have a target set up at, say, 100 yards; let's further assume that a constant breeze blows across the target from left to right. Let's assume that you have three types of bullet, all of the same mass (180 gr,): a jacketed lead round-nose (like Remington seems fond of making,) a FMJ spitzer, and a jacketed spitzer hollow-point.
Now, intuitively, the round-nose will suffer wind-deflection more than either spitzer, but generically speaking, how much of a cross-wind do you have to have to get a "significant" (here assume 1") deflection of a spitzer bullet? The reason I ask is that I read (somewhere) that spitzers are "practically immune" to cross-winds---as opposed to round-nosed bullets. Application: in my case, I buy cartridges as inexpensively as I can get 'em, which results in bags of jacketed round-nose, bags of FMJ spitzer-type, bags of spitzer jacketed soft-nose, etc. And I can't help but wonder how goofed up my shots will be if I scope the rifle with the FMJ spitzers, then switch to the JSPs for assassinating water-filled plastic milk-jugs on a day when there's a bit of a crosswind.
