I'm looking to step up to Wilson type seater dies for my 308. I only go out shooting about 1x per week and I only shoot about 30 rounds per outing so I'm willing to sacrifice speed for quality. My question is do I need an arbor press or can I get away with a rubber mallet? Intuition says that wacking a die with a rubber mallet is not a good way to achieve a precise seating, but it is listed by many people as a way to use these dies. Would this still be a step up over Forster seaters with a Co-Ax press or do I need to upgrade to an arbor?
