Don't know how many peps on here specialise in one or a few calibres but anyway whilst cataloguing the collection i must have 40 or so rounds that came with the cases they have been pulled from but won't go back in. The neck of the case needs to be evenly expanded to accept the projectile. This problem took me back to the days when i had a steamroller and had to re-tube the boiler. I used a tool from Wicksteed Engineering called a tube expander and a 30mm version turned up in the post today I can only recommend one of these if you have only one or two sizes due to the cost of a precision tool. This one expands from 28.22mm to 31.14mm and came in at 83.75 delivered! Expensive? Yes, but produces a perfect result. Wicksteed can be contacted on 01933 318555 if anyone’s interested. p.s. photo is a stock photo as i don't have a camera that talks to the computer with me at the mo.
