Question about quickload

[Alabama556]

I just got my quickload software and started playing with it and have a question

I am looking at 180 grain bullets in a 300 wby mag with r22 powder. When I put my load in (84.5 grain r22) and it says don't use the load. The data in the program lists 78.3 grains as the maximum charge but the alliant website shows 82 grains as the max.

I have been using this load in my gun for many years with no pressure signs.

What am I doing wrong. So far this software seems useless for the 3 cartridges that I have tried it on.

Just go through the list and make sure all the parameters are correct. Measure as much things as possible. I worked on a load for 2 month, I just got QL and it predicted MV to 3 FPS with out messing with burn rate. And barrel time was .004 ms from OBT chart. I'm impressed so far.

1. You will need to adjust your case capacity for grains of H2O.
2. Set your correct OAL
3. Set case trim length

You will need a chronograph to get your loads actual fps and then adjust the burn rate in Quickload until the velocities match.

Quickload is nothing more computer generated "guesstimates" that you have to tune to get close to your actual velocity readings. After you adjust your burn rate to get your velocities to match you have no idea if the chamber pressure readings are correct.

Quickload has its good points and its bad points, and all you have to do is look at the different loading manuals and see the variables.

Example, my Savage .223 does not have a SAAMI throat and its throat is longer than my AR15s throat, so the parameters within Quickload will never match actual readings. By the time you get done playing with and adjusting Quickload your could have loaded a workup load and gone shooting and gotten real world results.

So the goal is to figure out what your real pressure is after adjusting all of the variables that you know? Ie velocity, case length, pal, bullet length, etc?

I use it to find barrel time, didn't have to adjust capacity or burn rate, it was dead on.

My point being you need a chronograph to input the actual velocity in Quickload by changing the burn rate of the powder and other variables. Meaning your adjusting Quickloads guesstimate to your real world chronograph readings or changing Quickload to read half way correctly. If you really want correct data buy a chronograph and a Pressure Trace strain gauge and you will have actual measured data and not computer generated guesstimates.

Now open a reloading manual and input this data into Quickload and see how far apart the readings are between the manual and Quickload. There is no way a computer program can accurately output data to match all the variables for every firearm made in a single caliber.

Don't get me wrong, I have Quickload and its a neat "TOY" for playing around, "BUT" it wasn't worth the money spent for it. And the money could have been put to better use with anything that outputted real data and not guesstimates. If I had to do it over again I would have used the money toward a MagnetoSpeed chronograph and "REAL" data.

I have all my loads chronographed and the data output in quickload does not match up. I bought a magnetospeed today so I will verify my loads with it when I get it. I have been using my pact chrono for a while now with good results. I just can't figure out what quickload is good for if you have to manipulate so much data that is not "known" to get the results in the program to match up to your chronograph readings.

Why would you compare quick loads to a manual, Quickload is going to be much more accurate once you get it calibrated. Like I said my were dead on.

I just got quickload. Can you tell me where you enter your velocity data from the chronograph into quickload?

Thanks
