I have been using quickload for couple of years now. I don’t have latest version because I don’t shoot any new cartridges that I need data for. Also to add I’m not new to reloading and I’m experienced enough to know how to read pressure signs etc. I notice Quickload consistently gives me velocity lower than what I get from chronograph. I would like to use program to predict optimal barrel time and hence reduce load development time/effort. At first I was using Caldwell chronograph so I thought maybe it’s not that accurate. I just purchased CED and even that one is showing velocities higher than predicted by quickload. About 40-50 FPS higher. I have tested this with 3 different firearms(two 308 and one 7mm-08), all 3 using different bullets and powders. I have measured and entered correct values for bullet length, cartridge OAL using same bullet, barrel length, measured case capacity(filled to overflow limit). If I try to adjust powder burn rate(as suggested by internet to match velocities) quickload predicts pressure to be higher than safe limits for the cartridge, but I believe it not true because I don’t have any pressure signs at all. Primers aren’t flat, no ejector marks, no heavy bolt lift and plus lots of people are running these loads in their rifles, so known good loads. For example my 308 load for 200 gr Hybrids Bullet I used for data measured at 1.5” Cartridge OAL 3.110” with same bullet Barrel length 30”(measured) Case capacity 56.7(Lapua brass measured average) Bullets are coated with HBN so friction proofed, using standard 0.66 number. 43.8 grains of varget as per quickload should give 2611 FPS at 56323 psi. Chronograph consistently shows 2650-2660 FPS(measured at 10 ft) Lots of guys I know are running 43.1 to 43.3 to achieve 2650-2660 FPS from this bullet in their FTR rifles. My bullets are coated and OAL is slightly longer so 43.8 should be around 2650ish which is confirmed by chronograph. Im getting similar results from 308 loaded with 185 jugs and H4895 and 7mm-08 loaded with 154 interlocks over IMR4895. Can one of you gentlemen please run above numbers for 200 hybrids on your end and see what kind of results are you getting? Just for those who are gonna say contact Neco, I did send an email to Neco about a week ago and haven’t heard back from them, they are probably backlogged. Edit: I have shot 200 at longish range(900) but lost all data during move. Plus bullets are pointed so B.C. is slightly different which makes it little harder to reverse calculate accurate velocity.
