Plastic wad change in Bullets, Cartridges and Reloading Posted October 18, 2019 3 hours ago, figgy said: Can you not look for a recipe for the wad and components you have got. Put your components on here and a member might have a recipe for you. I change wads at will but it's not recommended, can push pressures over the limit. Hi figgy, cheers for the reply. Someone on the Facebook group was able to advise me about changing the wads & altering the powder charge. Someone a lot more experienced than me.
