I just got my copy of Quickload in the mail yesterday and started entering data for some of the reloads I've done before.

My H335 load looks good, but CFE223 looks way off in QuckLoad.

I originally used data from Hornady's manual (9th edition) that shows 22.8 - 27.5 grains for a 55 grain bullet.  Working this load up years ago before I had a chrono, I settled on 24.6 grains as an accuracy load (as accurate as can be with a Hornady 55gr fmj).  I finally chrono'ed this load last week.

Chrono at 7 yards and 63 degrees F, 10 round average with a 16" barrel was 2611 fps.
QuickLoad shows this load should be only 2384 fps (70F default temp).

This is after entering all of my cartridge information including H2O capacity of fire-formed cases, trimmed case length, and bullet length/seating depth.

Even comparing QuickLoad to the published Hodgdon data, QuickLoad just seems way off (under).

Am I doing something wrong in QuickLoad?  Are my expectations of QuickLoad too high?

I can tell you that CFE takes some extra powder to get moving for me.

27.5gr will make a 55gr do 3175 out of a 22" barrel. That's the same as 25.5gr TAC.

26.5gr TAC will do around 3300 from the same barrel, and from a 16", 3125-3150 range. All shot same day around 85-90*

Quite a while ago, on a 55* day, I had ran 26.5gr CFE for 3025 (22"), while 24.5gr TAC did the same velocity.

23.5gr H335 yielded 2914, equal to 25.5gr CFE, on a 47* day. Wolf gold shot 3250 in those conditions. Again, 22" barrel.

That may seem all over the place, but consider comparing the data I have to any you have, and see what quickload says. Because of the potential for inaccuracy of scales, consider the difference in charges more than the actual weights.

All shots here done with #41 primers, usually in WG cases, but sometimes mixed cases.

Thanks FritzTKatt.  The default data for CFE223 in QuickLoad shows about 200 fps slower than your reported velocities.  Using my adjusted burn rate numbers to match up my velocities, your numbers are very close.

It seems really odd to me that QuickLoad would be so far off for this powder.  It is well outside of what should be acceptable variance for a canister grade powder.

Comparing to Hodgdon's data... 24" barrel with a 55 grain projectile (Speer SP, as defined by the hodgdon data, loaded to 2.200" with a case length of 1.759".  30.2grains of H20):
26.0 grains - Hodgdon: 3,133 fps and 43,300 psi.  QL: 2849 fps and 34,279 psi.
27.8 grains - Hodgdon: 3,329 fps and 51,300 psi.  QL: 3072 fps and 42,622 psi.

I've never used quickload, but if you can consistently get 200fps (or whatever, high/low), then it may be usable.

Where you may get into trouble, is relying on that pressure data. Don't be stupid, work it up.

How does QL match my numbers with TAC? H335?

QuickLoad data comparisons given above in red.

TAC seems to be off as well.

H335 is fairly close.  Note, it seems QL is very case capacity dependent.  The numbers above are for my Lake City cases.  If I switch to the case capacity for my Geco brass (31.2 grains H2O for LC vs. 30.2 for Geco), the H335 load goes up to 2876 fps.  If I use the default data for 5.56 of 28.5 grains of H2O, the QL estimate goes up to 2959 fps.
My H335 25.0 grain loads chrono'ed at 2827 fps, and QL estimates 2819 fps (16" barrel).

I've never bothered measuring case capacity with water. No need to for *me*, I just load the shit and see what the chrono/primer says.

The majority of my cases are WG, followed by LC, and FC. Also a lot of CBC.

I have some prepared, ready to load brass, #41 primers, trimmed to 1.745. Of that I pulled 10 WG, and 10 LC (mixed year). I also have some fired GECO, of the same lot, untrimmed. I left the spent primers in so they will hold powder.

The WG averaged 97.9gr, and a case weighing exactly that will hold 30.4gr CFE.

The LC averaged 96gr. I also found a case weighing as such. It held 31.4gr CFE

The GECO (again, spent primers, untrimmed) average 96.8gr. Again, I found one of that weight, it measured 1.745 (oddly enough). This one took 31.3gr CFE. I found one prepared GECO case, weighing 96.8gr ready to load, but being short at 1.741, which held 30.6gr CFE.

These are random cases pulled from buckets, fired in God knows what chamber. Some of those LC might have been reloaded many times before I got them.

I put the cases in a cup, put my funnel on them, and poured powder until it mounded up. Then leveled it off.

Maybe you can work some capacity off that. You must have CFE223 on hand or you wouldn't be asking these questions

Soon enough I'm going to load up some of this CFE, as I just want to burn it up along with h335 and h322. I have yet to work up loads for them, so I'm going to make it quick and hopefully get at least 100rds of each to blast with.

ETA: I believe QL is generally pretty accurate, maybe you're off with your inputs?

Out of that same 22" barrel, WG/#41, 25.9gr TAC launches a 55gr Vmax seated to 2.240 to 3100fps at around 80*. That load is ridiculously accurate out of that barrel (considering what it is, the optic, and shooting conditions/position). Happens to be in some velocity/harmonic node when loaded a bit slow like that. Wondering if this load also gets calculated 200fps slow

Wondering how those parameters compare to other loads listed. Did I mention I seat the 55gr FMJ (hornady) at 2.200"? Hoping to give you enough data that you might find more correlation.
