On the recommendation of my buddy at Hausofguns.com, I picked up a 1lb Star Exploding Target a few weeks ago and just finally today was able to set it off with my dad while visiting their home here in Middleburg.
This was a first for both of us.
We used a 55-gr .223 bullet to impact the target to set it off.
Some info on Star Exploding Targets:
Star Targets are very safe when used as intended and the directions are followed. Once mixed it must be impacted with a high velocity round to set it off, it will not go off if it dropped, shaken, kicked, even lit on fire. You can hit it with a hammer, shoot it with a pistol, or throw it off your roof. It takes about a 40 grain bullet traveling at 2200 FPS directly impacting it to cause it to go off, anything below these requirements will not set it off.
Each target contains two components, a base and a catalyst which is pre-measured for each target and sealed in a bag within the target. To prep the target for use (first read and ensure you understand all directions and safety instructions), simply open the target, remove the catalyst and dump the contents back into the target container. Seal the container back up, mix vigorously for 45 to 60 seconds (the entire contents should be a light grey color with no white left). Place the target at a safe distance and location then you are ready to shoot. Not for human consumption.
I can honestly say that I have NEVER set off such a large explosion in all of my life. These things are absolutely incredible and I can’t wait to get my hands on a few more!
