My 550c came today and just got it set up and while doing the 556 kit first, I noticed the funnel for the powder drop was different than the one I had in the 750.... It caught my eye instantly.. thought hmmmmmmmm.... Got the 550 up and running and not a dang drop of powder spilling!
Im kicking myself because I got that 223 conversion kit for my 750, second hand and trusted the person.. guess he got the parts mixed up because he had A LOT of kits for sale. (getting out of reloading)
Lessons learned for sure... and though the 750 was a beast when it comes to speed, I do love the 550c and Im pretty sure after all this, I wont part ways with the 550C again, and just keep it and get a 750 next year if my shooting increases.
Thanks again for all the replies and help... I let my temper get the best of me on this one, but in the end, Im glad to have the 550C and a little money left over compared to the 750 and case feeder.
