Looking at Sierra data, and cross referencing with yours, I might go up to 43.5 grains. You generally won't find the max load to be the most accurate anyway...

Let us know how they turn out.
yeah, I'm not really wanting to go up to max data. .243 is a barrel burner anyways, so by using a slow-ish burning powder and trying to keep the pressures down I'm hoping to keep it as manageable as possible for the old man.
