how many bricks would be required to stop a 45cal. @ 600fpe?
You would need 6" minimum of putty for such high energy projectiles. Even then we suggest a 3/16" steel plate behind the putty.
Would this stop an air rifle 25gr pellet at 15 yards?
Will it stick to the inside of a steel .22cal Bullet Trap? If so, how many bars will I need? Like the Do-All Outdoors Bullet Box, Pellet & Rimfire Trap, 10"x11"
How many bricks are required to refill the A.G.E. trap?
How malable is the putty?Is it soft enough to roll out to cover a larger area?
Yes it is but you will need to keep it fairly thick to be able to stop the projectiles.
how much area will one 6 lb. brick end up covering ?
It depends on the thickness you want to use. The dimensions of the brick are 1 3/8" high X 6" wide X 10 3/4" long.
