Quick load software, how user friendly is it.

[jtoews80]

I've been hearing about this type of software for awhile and seen POP offer load comparisons based on this data. My question is, how difficult is it to use, for instance do you have a list of known components and build your data from there or do you need to get actual mathamatical burn rates from an update server or even find them out with formulas?? Or Perhaps measure bullets, do displacement calculations for bullet displacement/usable case volume?

I am curious as I often end up trying loads with other bullets, cases or sometimes even trying to take an average of the loads for two listed powders and find these two listed powders and the one that isn't listed which I want to use and roughly calculate how much would be a good starting load to work up from.

At the moment I have three loads which shoot well and chrono well that I have worked up that I am not sure will be useful because of possible brass and barrel wear.

Unfortunately, I end up at this juncture quite a bit as I often help my brothers load and they are new to it. Thing is I don't like taking chances with their guns. It is one thing to test and play with your own as the consequences will fall on you and your own equipment, another to work up a potentially dangerous load for someone who may not notice the signs of pressure.

Quickload has all the numbers you will need except for your barrel length which you imput. It is a little overwhelming at first, I'm still learning how to use it and have had it for a few months now. They have a very extensive list of bullets, powders, and calibers. I would almost guarantee that it will give you way more info that you "need", but it's good to know. And then there is info that is just way over my head!

Bottom line: IT IS VERY WORTH THE MONEY!!

It should not take you all that long to fulfill 80-90% of your needs.

Now if you get into designing your wildcats etc etc it can be a bear....but only because I never explored this issue.

I also like the trajectory or exterior ballistic program which is included.

POP, humour me and check if these loads are normal pressure, please. I don't want to ruin my 30-378 brass. I've tried 110-112 grains of retumbo with a 180 grn AccuBond bullet. The 110 load chrono'd @ 3450FPS, 111 @ 3570FPS and the 112 grn load @ 3605FPS. The bolt was a little tight on the 112 load, but the primer and case head just below the belt looked ok. With 200 grain Accubonds, I tried 104grns and 105 grains, with not appreciable change in velocity if not a slight loss, so 104 is great perhaps reduce to 103. I loaded the 130grain AccuBond with 68 & 69 grains of Retumbo, the 69 produced 3280-3331 FPS, although I loaded those last rounds in a hurray and the spread may have been due to poor loading.
LOL, I'll probably buy the software at some point just to be able to quit guessing. It's much appreciated.

Pop I agree with it not taking to long to figure out 80-90% of it. I started playing around with the wildcat side of the program and I'm not quite sure I have it all figured out yet but gives me a rough idea of what I'm after (I think), and is prety dang cool!! If a guy has a few hours to sit down and just play with everythinng and figure it out you'll have it down in no time. Prety much it is like having every load manual ever made and then some at your figertips :twisted: .

The one thing that is taking some getting used to is how "padded" the data is for saftey reasos. Can't say I blame them but it would be nice to not have to work up from so far down.
