Just to say,
The very generous chaps at Brock and Norris allowed to have a nose around their workshop and donated 25 ( now deactivated) barrels for academic research. These will prove very useful in the teaching of forensic scientists. Very Very friendly chaps who were happy to take time out of their day to chat and explain things as well as giving a few very interesting demonstration on how their beautiful rifles are built. As well as putting me into contact with other companies who may be able to help.
Very impressed with the open honest and friendly atmosphere, and support of all shooting related activities.
Thanks again Chaps
