I agree with Intel6. The priming system on the 750 is a step backward into the 550.
Setting off a tube is no joke and I'm glad it's never happened to me, but I've seen the after effects. And, it's the reason I always wear shooting glasses when I'm running either my 650 and even my 1050.
The upgrades on the 750 vs 650 were all, at least what I could see, copies of aftermarket upgrades made for the 650 over the years like the roller cam.
The only upside that I can really find is that the 750 is a bit beefier than the 650. But the primer system is just no bueno for me. If given a choice, I'd pick a 650 over the 750.
Now, the upgrade from the 1050 to the 1100 is a bit more pronounced and better. The stroke is better, the indexing is better and the swager is better. At some point I'll probably dump my 650 and buy a 1100 so that I can run large primer on my 1050 (45 and .308) and small primer (9mm and .223) on the 1100. Be nice not to have a shower of Varget every rotation.
