You will find that decapping bulk brass on your xl750 will leave it disgustingly dirty. You might try doing your decapping and primer pocket swaging on something like a Lee APP press it's cheap and fast.

A friend had the same issue your having and asked me for help I found his press mounted to a 3/4" plywood work station with C-clamps. After bolting his press to a proper solid bench that is bolted to the wall and floor it works fine. My 3 Dillon machines are mounted on a 5/16" sheet of steel that is bolted to my work bench and I can't remember the last time I had a damaged or upside down primer.

I just switched to Fiocchi small pistol primers and have noticed they take a lot less pressure to seat than Federal or Winchester. I measured a few and found them to be the same size but my be made from softer brass.

Spokewrench, I'm 5'7" and have found that mounting my reloading machines on a bench 40" high is right for me I can see the powder level in each case and I get very few high primers. I almost never get a high primer when using the stock Dillon lever and round knob but the roller handle is very cool and my shoulder likes the roller.

If you have been loading on a Lee loadmaster it my take a little getting used to priming on the up stroke. I very seldom have high primers when loading my XL650 or my new XL750 when I'm standing if I set I'll have about 5% high primers. Don't give up on your XL750 if you are one of the few that cam make a Loadmaster run you will have the Dillon machine running like a top.

I've been reloading on a XL 650 for many years it's a great machine the only problem with it has been the priming system. Yesterday I set up my new XL 750 and I like it Dillon has addressed all of the issues the 650 had.
