I have been shooting and casting for my Airforce 50 cal for close to two years and it has been a learning curve . I as many others would love to part time cast and sell airgun slugs. My 50 Texan needed a complete rebuild after a 1000 rounds. The Umarex hammer doesn't seem to be slinging much lead and time will tell if AEA is long term reliable and has long term parts support. I think the air guns cast slugs and pressed slugs are for the most part very accurate and reliable. Point being I think the air guns are going to need to be more reliable before there is a demand for slugs. The need in the market seems to be for quality pressed slugs small caliber.22 to 30 cal. Is Nielsen speciality ammo and Mr hollow point meeting the demand? Thank any of you for you thoughts. These are my .510 slugs from 650 grain to 460 grain
