Looking for someone with quickload to run some numbers for me

The makers of Quickload are trying to get people not give out this information as they are losing money. Also, there is just too many variables. Get you an assortment of reloading manuals and start at minimum and go up. Your rifle will tell you when you have a good load. Brass can vary from lot to lot as does bullets and powder. Weather conditions play a big role. I`m not trying to be rude but no two guns are the same.
Why would anyone ask complete strangers on a public forum for a max load?
And as stated earlier, there are way too many variables. I find that I usually have to shoot two loads at least one grain apart to "calibrate" QuickLoad to my individual barrels. Case water capacity is also necessary to get results that are even in the ballpark.

+1 to Nomad47.
Or, just buy QL. It's really not that expensive compared to some of the stuff people shell out money for in the shooting game.
I don't hand out QL data mostly because of the variability Nomad47 referenced - if I give you something without ALL of the pertinent information, I could be giving you a load that is well over max because I don't know something about your setup or you quoted the wrong number at me for some measurement. Not interested in being liable for that.

From the Hodgdon web site http://data.hodgdon.com/cartridge_load.aspcmorsch said:
200 GR. NOS AB IMR IMR 4350 .308" 3.300" 50.0 2364 45,900 PSI 53.5C 2550 57,200 PSI
So if your are chronographing your load and you are not yet at 2550 and using all the normal methods of monitoring for pressure signs....
As for QuickLoad, put it on your must get list.
Oh and you should be looking at accuracy not speed/more powder.

Quickload gives you computer software generated guesstimates, to get accurate Quickload data you need case internal volume and a chronograph to calibrate and adjust the Quickload output. I have Quickload and I do not have a chronograph and can tell you that sometimes Quickload "without" a chronograph can spit out some really wild a$$ guesses even with the correct internal volume.
As a example of computer generated guessitmates my computer spellchecker keeps wanting to change Mauser to Mouser.
(there might be a rat in my computer) :
The Nosler reloading manual lists 53 grains of IMR-4350 as the max load with the 200 grain bullet, and 49 grains as the accuracy load.
As stated very well above by Dave Berg if you plan to go higher now is the time to go in baby steps and watch for signs of excess pressure.

FWIW I have two AR15 rifles and a .223 bolt action rifle, each rifle has a different type chamber, throat and twist rate. The bolt action .223 has a longer throat than both military type AR15 rifles and its a factory chamber.
Without a chronograph Quickload just gives guesstimates, and each of these "similar" rifles would need a different Burn Rate Factor correction if a chronograph was used to get accurate readings on all three rifle.
My point being without the OP giving velocity reading no one here could give accurate Quickload data anyway.
Quickload without a chronograph can give you good "ballpark" estimates and help select efficient powders for a given barrel length. BUT they are still computer estimates and not real data.
If you just take the reloading manual data from several manuals and even correct for case capacity and input it into Quickload the output data can be way off from the manual. You have the Lyman manual using pressure test barrels and transducer pressure readings and other manuals using strain gauges for the testing. Then you have Quickload guessing about all the variables you can have with individual barrels. Without a chronograph and making adjustments to Quickload the output data is a guesstimate.

Amen, BigEd, Dave Berg, and others.
My powder Ba's (burn rates) are different for my 6SLR and 243Ai even though I have same length and twist barrels with nearly the same free bore. The Ba's are even different between 105 Berger Hybrids and 105 Amaxs seated the same in the same barrel - same weight bullet, same seating depth. So apparently different bearing surface lengths account for needing different Ba's.
