All of the holes are the same, the only difference is the 550/650/750 mount is taller and it comes with the loaded cartridge bin bracket for the 550. The 650/750 mount is shorter and it does not have the bracket. I have both.

I heard this Supposedly voids Dillon's warranty.

Use the same swage rod but there is an adapter for the guide rod to do 9mm/38s. There is also one for. 40 and one for .45 The 9mm and .40 adapter go on the 223 guide rod, the .45 goes on the .308 guide rod. Of course you don't need the adapter to swage 9mm, but you don't NEED a Dillon press to load ammunition.

I have never seen a riser block for the 1050 like you describe, but you could probably get someone to 3d print one for you fairly easily.

This is the reason why they adapted the 550 priming system to the 750, if you have a detonation it will only be one primer and will not chain react the whole magazine. I'm not saying it's not possible, but it's not probable.

If they are 7/8 x 14 they should. You should use the Dillion 1" lock rings though. 550 head is small and the bigger lock rings are harder to use with the 550

I cast several hundred at one time, and powder coat different colors. Most of the time they all weigh the same, but the color represents powder charge. Sometimes I just load rainbow loads of all the same powder charge, but all my loads are bagged with a tag that shows what's in them. Sent from my Pixel 4 XL using Tapatalk

This mirror on Amazon works really well for a powder mirror. 1 wrap of electrical tape helps it stay put. HARDK Inspection Mirror Magnetic Base Welding Magnet https://www.amazon.com/dp/B07HNBWJ3M/ref=cm_sw_r_cp_apa_i_66W9DbW729TZG Sent from my Pixel 4 XL using Tapatalk
