Hi, I live in the woods and would like to use a paintball marker as a plinker as it is less of a fuss than using my 22lr, I don't want a firearms licence anymore. I can get a good price for the dye dam and find it very nice looking and the fact that it can fully auto is great. The problem I have with using it as a pinker is that at 280fps it is to slow to really do anything from any distance. I'm looking to up the velocity to the 400fps plus range. closing in on 500fps would be ideal. I'm looking at shooting firststrikes but am aware that and that velocity they might burst inside the barrel so will probably use practice balls. What would I need to change for the marker to be able to handle that kind of output pressure? Any help would be appreciated thanks.
