Dan,
The bullet isn't long enough for that COAL. It would be completely out of the case. Although, QuickLOAD's bullet database isn't always correct. It's best to measure a bullet and overwrite the defaults. I don't suppose you happen to have bullets cast from that particular mold that you could measure?
At a COAL of 1.680" QL shows a seating depth of 0.620 (so fairly deeply seated). The .30 Carbine appears to have a neck length of right around 0.308". So with 100% neck tension that would give you a COAL of 1.992". Going as low as 75% neck tension (my personal minimum) would give you a COAL of 2.070".
And I can't completely take the minimum load density out of the equation as 29% is lowest allowed.
***USE THIS DATA AT YOUR OWN RISK***Cartridge : .30 Carbine
Bullet : .309, 180, LEE C309-180-R
Useable Case Capaci: 16.677 grain H2O = 1.083 cm�
Cartridge O.A.L. L6: 2.070 inch = 52.58 mm
Barrel Length : 18.0 inch = 457.2 mm
Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 40610 psi, or 280 MPa
or a maximum loading ratio or filling of 110 %
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.
