So... here's what happened. I've been running a 650 for awhile now ( and a Square Deal since the 80's ), swapping back and forth between 9mm and 45 acp on the 650. I decided that swapping back and forth was too time consuming so decided to get another 650. This is course was perfectly timed to coincide with Dillon pulling the 650 from the menu. Ordered one from Amazon, which was promptly cancelled as "out of stock". I figured it was a 'sign', so I went ahead and ordered the 750. Set it up yesterday and here is my list of initial impressions.
There is a reason why you usually see pictures of the 750 from the back. From the front, you have the priming assembly and rod pretty much in your face. Ok, so I sit more to the left now. The priming tube is now directly in front of the powder measure, leaving almost no room to manipulate the early warning primer box assembly. It's pretty tight, and no matter which way you aim the large blue buzzer box, it partially obscures the powder measure. I use a mini MrBullet feeder and while it does fit, it dances between the powder measure throw bar and powder tube, somewhat precariously. I figured the first thing I needed to change was the primer early warning system. It's just too big and in your face. I ordered a round mini buzzer, CR2032 battery holder, mini reed switch and an assortment of magnets. I'm going to make a buzzer that sits on top of the primer tube requiring almost no space and activated by the reed switch coming into proximity of the magnet. If I can get it to work ok, that should take care of the obstruction of the warning buzzer box.
The priming system, while larger and more obtrusive, has the advantage of not needing a primer ski jump for ejected primers, and no dust pan required to clean up the mess if you didn't install an after market ski jumper. Improvements to the indexing smoothness were immediately evident, though the instruction manual has grown significantly with regards to adjusting all the possibilities. I am still confused about the tiny hole under each shell position, perfectly centered and just waiting to be plugged up with powder. It's probably in the manual somewhere, but I didn't immediately see it.
I ordered just the base unit, as I had everything else and naively intended to swap the case feeder unit over... back and forth. Ya, on second thought, I'll order another case feeder and skip the swapping on that too. What was I thinking....
And lastly, I suppose there are fewer parts to wear out on the priming system, and cleaning will be easier. That is a plus.
