I ran some numbers through QuickLoad for the Speer 130 grain SBT with a 16" barrel.
Do these look right (safe)?
-----------------------------------------------
28.5 Grains H335
COL: 2.255"

Max Ch. Pressure: 67,000psi
6.6% compressed charge
-----------------------------------------------
25 Grains Reloder 10x

Max Ch. Pressure: 62,000psi
8.1% compressed charge
-----------------------------------------------
26 Grains Norma 200

Max Ch. Pressure: 71,000psi
2.5% compressed charge
-----------------------------------------------
27.5 Grains X-Terminator

Max Ch. Pressure: 68,000psi
8.5% compressed charge

Check out the Speer manual below for the 130 Gr. bullets. According to Speer, those loads produce 55K PSI. QL doesn't really work with the 6.8SPC without tweaking it.

Well then I guess the next question is: How reliable is QuickLoad?

I've found some info on the forum regarding people using the 130 grain Speer and a couple loads that are similar to the ones I have listed. I just found it crazy that people were able to load THAT bullet if the pressures achieved are way above 55,000.
Therefore it makes me wonder if QuickLoad needs the tweeking.

QL needs tweeking for the 6.8SPC. Constructor and Tim_W use it, but they know how to tweek it.

I already got the PM and answered with a novel length Pm actually I had to cut it in half because of the 5000 word limit. cold you will need to disable that for me or I will not be able to send half my PMs Actually it really does need to be changed as you can not send copied instruction or posts that are long. Its a real PITA for me.

Actually no matter what cartridge it is QL must be tweaked. The data they give you by default is only gernal averages. The bullet and powder data is fairly accruate but you must confirm. Barrel case etc specs much for every single cartridge done and filled in. The thing with Ql is it has great formulas and equations to get you amazingly accurate predictions but they are just that formulas. You must supply it with accurate data. Crap in crap out gold in gold out.

Never arbitrarily load a charge recommend by QL if you do not have a expert level of experience with the program or you have reloading manual data or confirm it with. You will always have to work up tp a max load. QL is not a short cut. It main benefit is to finding the best powders to try with a particular bullet in your barrel. The other once yiou understand everything and have a chrono is you can use it to find the accuracy node charge much faster that with normal round robin loading program again you have to have everything inputted accurately.
