I almost bought just the case feeder for the 550 but decided against it. I ordered the 650 with case feeder and mr bullet feeder from double alpha/alpha dynamics. There is a decent deal if you order them as a package since it seems nobody discounts any Dillon products. I don't know if that is double alpha's normal pricing or a sale item as I have never looked before. I will need to get new qd plate and ergo press arm from inline now and besides the shell plate bearing kit are there any other upgrades you guys suggest? Also, I was going to order the redding carbide comp die set for 40sw, is that advisable or not worth the increased cost?
