No offence, but your hand primer isn't the cause of FTFs. About 99% of primer failures for new reloaders is improperly seated primers. Primers have to be seated all the way to the bottom of the pocket to fire with the first strike. Before you start fiddling with your guns, just seat all the primers all the way to the bottom, and then add a little more pressure to make sure they are bottomed out. Disregard any "below flush" measurement, just bottom them out.
I tried hand primers (3 from 3 different manufacturers) and none seemed to fit my hand, which surprised me as I've been making a living with hand tools for 60 years, but I would have to reset the tool in my hand after each squeeze and for the first time in my reloading career, I got FTFs. I went to a ram prime, and have had 100% successful primer seating for the last 20+ years...
