I'm wondering if I can safely go over the 104gr charge that's is on the load data due to me seating the bullet out further than the original spec. What is the pressure at with the 220 gr bullet and 104gr us869 with a col of 3.60?
 
What is your H20 case capacity and velocity / powder charge to determine a more accurate assessment? And your temp in your area.
 
H20 113.1 gr and and wanted to see if I could safely get up to 105 to 106 gr of powder 40-50° average
 
You seem to be in the ballpark.

Code: 
Cartridge          : .300 Rem Ultra Mag
Bullet             : .308, 220, Hornady ELD-X 3078 G7
Useable Case Capaci: 96.717 grain H2O = 6.280 cm³
Cartridge O.A.L. L6: 3.600 inch = 91.44 mm
Barrel Length      : 24.0 inch = 609.6 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 64200 psi, or 442 MPa
or a maximum loading ratio or filling of 112 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.

Yeah. It shoots beautifully. I still am newer to the hand loading scene and don't quite know enough to know if I'm getting all of the potential out of the cartridge.

Your load generates good speed and a lot of horsepower, more than enough to handle most shooting requirements with a 30 cal.
Keep in mind that pushing the upper limits will cost you case life from loose primer pockets.

Could you see what length of barrel would get me to 100% prop burn?
 
Good afternoon you've been super helpful and I was wondering if I re barreled my rifle up to a .338 cal and renecked the 300 rum case to 338 edge if you could use your system to see loads. The renecked 338 edge has a h2o of 118.2, max chamber pressure of 64500 psi, it'd be at the same altitude and temperature. And I would say I would use the 230gr ELD-X. And C.O.L of 3.75 inches.
