I was shooting Berger 205gr hybrid out of my 300WM with a load developed at .005 off the lands. Nicely putting 3 shot groups into .3 moa but loaded single shot. Now I want to load from the magazine seated max length and of course groups opened up to a tad over moa. If someone could give me an idea where the nodes will be a break for me.

Need to know your original powder charge, velocity, barrel length, cartridge OAL, mag length to give a realistic answer
 
Hope this is what you need. Powder charge 73.6gr, velocity avg 2880fps, bbl length approx from chamber thread start to end of muzzle brake threads 25 1/4”, cartridge length 3.34”, mag length 3 1/2”.

You say the cartridge length was 3.340". That will fit in to your mag length. What was your original cartridge length that you had to single feed?
 
Just an fyi, your barrel length is measured with a cleaning rod from the bolt face (with the bolt closed obv) to the end of the barrel.
 
I input the data you have, and I would try 72.0grs, 72.5grs and 73.0grs H1000 with an OAL of 3.340".
One of these loads should be on a half-node.
 
QuickLoad is modelling software. If there is data missing or incorrect then it won't output accurate results.
The original OAL of your cartridge when you were single feeding would be very helpful.
It would also help a lot if you load a round with an OAL of 3.340" and determine how far the ogive is from the lands. Shoot 3 of these new rounds to get average velocity and I can revisit it for you.
 
I believe Berger uses QL to create their data, and they use the program's default start pressure of 3626psi which isn't realistic for most rifles that don't have 1/4" of freebore. This makes for higher powder charges than you'll be able to do in real-life.

The further off the lands you seat a bullet, you'll have to add some powder to recover the pressure loss from the longer jump.
