Oh my, I am outnumbered about 100 to one. I use my Dillon 550B, and one at a time, now that I load very few cartridges and weigh every charge. Yeah, it's slow, but it's either that or tv or a book.
I like the Dllon press. I have all the leverage in the world, if I needed it, and can easily feel the primer hit the bottom of the pocket.
My bud has a handprimer and was loading many of his with high primers. He also was having ignition problems, of course.
Yeah, I'll stay with my Dillon, but I know the handprimers are good stuff.
Of course, I didn't go with a digital scale until last year; my Ohaus 505 worked for me for 50 years without a hitch. I still use it, occasionally, as another backup for my RCBS digial scale. Also, I use my check weights, 10 grains and 20 grains, as my digital scale doesn't hold zero very well.
