Pressure Trace: PN45 A2015, 300rem jhp (Sabotless)
The burn rate of 2015 suggests that it would be useful as a duplex with light bullets or as a single with heavier ones. I traced this as a single because there is not much out there for it. Results were not far from QL predictions with a 99% powder burn. Predicted recoil for the 75gr load with a 300gr bullet approaches 32 ft. lb for an 11 lb gun.
TG
Gage and Module Manufacturer = RSI PTII Bluetooth model.
Trigger Sensitivity = 7. Strain Gage Voltage =5.096. Gage Factor =2.11. PSI Correction Factor: 5kpsi.(calibrated to my standard load) Rifle Stand: Caldwell Lead Sled. Altitude: 450 ft. Chronograph: Chrony Alpha Model 8 ft from muzzle. (13 fps. added to all recorded velocities to correct for distance of chrony from muzzle.)
Barrel Type: PacNor .45 Cal Muzzleloader. Barrel OD = 1.06in. Barrel ID = .452in. Barrel L.= 23.125in. from front of breechplug.
Breech Plug:Savage Std. (screw-in ventliner) ventliner orifice .032 in. Sensor dist fm BP=1.125in. Bullet Diam.= .458in. Resized to .448in Type= Remington 300gr. jhp.,unknurled. Sabot:None. Wads: Lubed wool over .06x.462 fiber wad. Primer: Fed 209A. Powder: Both Traces: Accurate 2015 75gr.
Shot fm. dirty barrel. These loads seemed safe in my barrel under the test conditions but may not be so in other conditions.
