I woke up around 430pm Today, working on the weekends and overnights shift has me attempting to sleep during the day, and I was hoping to get this done yesterday but the weather was not cooperating and was pouring rain all day. Not ideal for muzzleloading. I was able to catch a break in the weather and found conditions temperature wise, similar to what I'll be hunting in for bear season this fall. I figured that was good enough for me and headed off to the range.
I was able to measure out 120 grains by volume of Blackhorn 209, and selected 3 shots worth, and got the ELR's ready to go. I placed my chronograph out at 5 yards. I registered a speed reading from the first shot of 2,226 fps, 2,164 on the second shot, but after ripping the rifle apart between each shots for cleaning, which is my standard for muzzleloading, I saw that I had a little blow back, placed an O-ring on the third and final primer for a speed reading of again 2,226 fps, at 5 yards. After hand correcting this with the Vortex LRBC I was able to register a muzzle velocity of approximately 2,238 fps generating 3,113 ft lbs. of energy. I had a 3 shot group of 2.29" with the flyer being the second shot with the blow back, and the first and last shots cutting each other's holes for a 1.17" 2 shot group.
Overall this is going to be a top contender as a load work up, for my rifle for overall use, whether it is deer, elk, moose, bear, this is hitting harder than a Barnes 45/70 Gov't TSX FN 300 grain round, which is more than adequate on bears or any animal in North America at close range. I did a comparison of my collected data with Barnes Vor-tx Rifle Ammunition and this directly compares to a 7mm Remington Magnum and beats the performance with the 140 grain and the 160 grain TTSX BT bullets in kinetic energy. Below are comparison photos as proof from the Barnes website.
