OP hbdlux68 Campfire Greenhorn H Joined: Dec 2012 Posts: 28 North Alabama	Not sure if this is the correct place to ask but looking to see if anyone can run a quickload data for me? 7mm mag, 150 hornady eld-x (or nosler e tip 150), IMR 7828, cci250 primers, Winchester brass, 3.300 coal, 26” barrel. Just trying to see where the burn times end up at. Any help would be greatly appreciated. Thanks

At your specified COAL are the bullets touching or jammed into the lands? “There are three things all wise men fear: the sea in storm, a night with no moon, and the anger of a gentle man.” ― Patrick Rothfuss, The Wise Man's Fear

Sorry, I just realized I never got back to you on this. Apparently, my version of QuickLOAD doesn't have the ELD-X. The last update I did was about 2 years ago.

Using the 150 grain Nosler BT (@ 1.300" length)

USE THIS DATA AT YOUR OWN RISK

Code

Cartridge          : 7 mm Rem. Mag.
Bullet             : .284, 150, Nosler BalTip 28150
Useable Case Capaci: 74.340 grain H2O = 4.827 cm³
Cartridge O.A.L. L6: 3.300 inch = 83.82 mm
Barrel Length      : 26.0 inch = 660.4 mm
Powder             : IMR 7828 SSC

Predicted data by increasing and decreasing the given charge,
incremented in steps of 0.291% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !

If I keep the Nosler 150 grain BT but increase it's length to the length you provided (I'm assuming for the ELD-X?) of 1.402" it shows about a 1.0gr reduction.

Knocking on 3,000 fps. WLRM primers, Remington brass. Kills stuff, a lot. P Obey lawful commands. Video interactions. Hold bad cops accountable.
