I have no idea what guns folks will be using, Tone.
The range of guns made in China is so diverse it's unbelievable, it ranges from the lowly b2 right through to copies of Daystate PCPs, and many of the Crosman based CO2 guns are converted into PCPs as well.
Don't worry about bringing a gun I have a bucket full of Chinese guns if you want to borrow one.
If you arrive tomorrow as discussed, Gerry, we'll have plenty of time to sort the job out and place a few obstacles about the range.
All the best Mick
