Thread: Indoor range

Talked to owner more and got more info. Council got involved and ended in a court ruling of 55 decibels but not sure where measurements are/ were taken from. Anyway using a modified container with sound proofing materials he got the initial blast noise etc down but the disturbance of the bullet passing through the air to the target produced 65 decibels. As said digging a trench and roofing it will be probably be the best and cheapest option. As luck would have it I may have found about 50m worth of old precast concrete slabs. Will be following up and then maybe make some forms up and make the rest. Thanks for you guys input. Will post the outcome if we give it ago but will be a few months at least.
