.5 lbs of tannerite at 60yrds is fine as long as it's not in something metal and you use the plastic container that it comes in..
I wouldn't be any closer than that.. There is also a point of diminishing return on Tannerite.. You can't just pour pounds of it in a single container and get an even bigger burst.
The bigger caliber and more energy delivered does make a difference. It does help to set off between 10-15lbs of it in an ammo can. it helps to get full compression and ignition. But don't be close to that.. In a dry lake bed it cleared all the weeds within a 20yrd circle.
In AZ, you cannot use it to take wildlife of any kind.. I thought it would be a lot of fun to to put it in the ground and use it to launch Prairie dogs. But, prefer not going to jail.
Check the local laws before doing it..
And, I hate to be the buzz kill, and man would i love to set it up with a backdrop to force the charge concussion toward the hogs to stun them or at least take out the ballance and then shoot them before they come out of it.. But, please don't tape it..
I did a lot of really dumb things as a young man with way to much testosterone and wow am i glad that we didn't have youtube. We very well could have been in jail. There is no such think as random and anonymous without being really really good at Tech.
thanks for the info and advice.
i am in canada and not sure of the regs but pigs are a different class of animal up here also.
i dont tape nothing and trust me i wouldnt even dream of posting it anywhere if i did.
i was after what the blast effect was at a safe distance.
i do have another spot where the pigs do come in at and its a
good 120 yards from a covered hi seat.
maybe i should set it up there just to be on the safe side.
timing is of the essence as the pigs rarely feed during daylight hours.sigh........
