I use QuickLOAD a lot before working up loads. But the latest update doesn't have that powder, or CFE-Pistol (or was that BE-86?). Anyway, one of those is one that many people say loads (at least in top-velocity 9mms) almost exactly the same charge weights as AutoComp...
So I'm asking if anyone has real-world experience with AutoComp charges, in 9mm, using 115-gr JHPs, give pretty close to the same velocities *in the same gun*, as identical charges some other powder...other than CFE-P or BE-86???
My own load/chrono results in 9mm using AutoComp, including correct case capacity and barrel length data, has shown that discontinued Winchester Action Pistol/current Ramshot Silhouette with its burn rate adjusted to my velocities matches closely, in loads predicting 26,000 or more PSI. But the modified WAP burn rate then deviates from reality in my AutoComp results at lower pressures. Alliant HERCO seems to match my actual results much better, based on nearly identical charge weights and velocities.
So has anyone played around enough to know what powder most closely matches AutoComp in the 9mm, with the same charge weights???
Thanks!
