So Ive got quickload and I really enjoy it. I dont have a chrony however. Ive always heard its very accurate for bottleneck cases but it lacks on straightwalled. Has anyone compared quickload numbers to a chrony on pistol cartridges? How did the results compare?

I'd PM Andrew Leigh if you dont get any answers. I bet he'd have some info.
If you are going to use QuickLoad, I strongly recommend getting a chronograph.
While I've used/depended on it for the last 8-10 years or so, I've always cross-checked
with multiple manuals AND THEN used actual chrono figures to backstop the likely/actual
pressures in that barrel, that case, that bullet that primer and that powder.
This is particularly important when using combinations not listed in the confines
of published loading manuals. Otherwise you are flying blind.
With pistol/straightwall cases, I hedge my bets by calibrating QuickLoad on the pressure
data supplied in some of the published manuals for a particular case/powder/bullet/OAL.
THEN I can vary bullet/types/weights/OALs while sticking to that powder calibration.

No. I always load within published data. Quickload often times helps me to decide where I want to be when I find 2-3 reloading recipes that vary a great deal. As stated earlier though, I stay within published data. A great example would be my hornady manual. Ive found imr 3031 in a .223 case to be in left field in this thing compared to other sources and quickload. (very light charges)
Quickload usually gets you within 10% of the chronographed velocity with handguns. Be carefull, it severly underestimates very short barrel guns like 2" snubnose revolvers. After a bit of experience, you can get an idea of how a hypothetical powder load will perfrom in the gun by looking at the pressure vs barrel travel curve. A nice initial bump followed by a good taper indicates a good burn and is probably being modeled properly. A shallow bump with the max pressure way down the chamber is probably not a good candidate powder and is probably outside the region where it should be burning and consequently, not a reliable indication of what will really happen.
It has been very helpful in estimating what powders will work durning these days of shortage, along with several load books.
