Link?Check out GRT if you haven’t already, may not be as good as quick load but it’s free and I enjoy messing around with it
Make sure you’re measuring each of your components and inputting that data, especially case capacity. Do t just rely on the default values. If you have data from a known charge there’s a tab you can go in and input that and it will then true the burn rate and should be pretty close for all its other predictions.Well, played around with it, and it velocities run a good 90-150 fps faster than my Garmin says. It doesn't account for primers? And I have Forster benchrest dies, not as good as mandrel and bushing, no annealer, so neck tension is iffy. 300 blackout
Never did that. What's the best way to measure capacity? Thanks.Make sure you’re measuring each of your components and inputting that data, especially case capacity.

Highly recommend not thinking in terms of "jump". Certainly, to start of with, you'll want to know where your lands is, typically because you either don't want to jam a bullet or you do want to jam a bullet. Knowing where the lands is helps you decide on where you want to start. . . like .010, .020, .030, .060 or whatever. Otherwise, focus on seating depth and forget about jump.What would .250" jump do to pressure and velocity?
It’s been very accurate for my long freebore .223 bolt. Not sure what’s going on there. Oh well, was worth a try.Idk man, I'm inputting book loads into it and it's saying they'll all frag.View attachment 8408913
My first crack at something like this, I'm probably missing a parameter or something.It’s been very accurate for my long freebore .223 bolt. Not sure what’s going on there. Oh well, was worth a try.
There are a bunch of tutorial videos for it. It is not the most intuitive program to use.My first crack at something like this, I'm probably missing a parameter or something.
Double check the book value for COAL. QL is showing 2.260 for that same load, which is quite a bit longer than the 2.070 I see on your screenshot. Max pressure is only 40761 and velocity is 2088. QL also shows that load to stop burning before the bullet exits the muzzle on a 28" barrel.Idk man, I'm inputting book loads into it and it's saying they'll all frag.View attachment 8408913

This is why I got QL, to play around with different parameters to learn things
Interesting. I checked my Hornady book...for that bullet it shows 2.090 COAL with maximum safe load of 15.7 gr Lil Gun. But it also states a maximum of 2.260 COAL for the cartridge which is what QL is showing. Maybe that's magazine maximum?I did, Lyman AR Reloading handbook 2nd edition. 2.075.
