A job for saturday??
I got a white coat (taken straps off it)
I got two pro chrono, one is bfta but its mine this week!
I will keep that at muzzle end as less chance me shooting it.
I put the other pro chrono at 50m (both read similar, bfta bout 5 fps + on average one behind the other)
I got 4 batches of pellet
I shoot, record fps. look at groups?
what do it do next?
