Any tips on getting the inside of the flex tube on the c/back cleaned then "dry" .. I can always still see small droplets of water in there, and think - mould! cheers ..
Yeah, Go down to your local gun shop and buy two of these. One for washing the tube, and another for drying the tube. If they don't have the woolen ones for the .303, just get a .410 shotgun one and shave the diameter down a little. They always have the shotgun ones in stock because they are more popular.
It's for cleaning out the barrel of a .303. Just put a bit of string on it and pull it through. It has an eyelet on one end for this purpose.
Or, what I used to do is get two pipe cleaners, twist them around eachother so they look like a barber shop pole, this makes them exactly the right thickness to clean the tube.
Tie one end of a piece of fishing line to the end of the pipe cleaners, and tie a cable tie to the other end of the fishing line. .
Feed the cable tie down the tube, hold the tube upside down and the cable tie will fall down through the tube and out the other end.
Before you pull on the fishing line and pull the pipe cleaner through, put a drop or two of washing up detergent in the tube, wet the pipe cleaners just pull them through. It's a tight squeeze so you have to make sure you've tied them on well.
Do this a few times and then rinse the detergent out of the tube.
Repeat this process with a dry pipe cleaner to dry the tubes inside.
