I need a new hydraulic press mainly to press gun barrels my old one is crap. AK barrels don't take much to press but these HK barrels are much tighter. What pound press do I need to get. I am sure the biggest I can afford the better or whatever. BUT will a new 12 ton do the job? 16 ton? 20 ton? I was looking at a 20 ton but if I don't need that big of a press I am gonna save a couple bucks and a little back pain getting it loaded. Thanks in advance.
