I’ve been shooting my DE .44 for a few months.
My initial loads with WW296 were too light for the gun and I worked up to 23.5 gr with the Norma JHP and Win LP primers in Starline brass.
It still failed to go into battery every now and then, so I polished the inside of the mag lips (600 grit sandpaper) and knocked off some minor burrs on the follower. Now it fine.
An alternate load is the 180 gr Hornady XTP over 28.5 of WW296. Oddly enough, it shoots to the same POI as the 240 gr load at 50 yds.
I need to chrono these loads.
All in all, the gun’s a pussycat to shoot. True, there’s a lot of recoil, but it’s totally manageable and there’s no pain, so the recoil isn’t an issue.
A common problem that I’ve read about is the gun shooting low with most any load. I ramped and serrated the front sight and went to the range with a file. 20-odd rounds later, it was shooting right on the sights at 50 yds.
Holsters for this thing are a problem. The ones I’ve seen advertised are either crap or the dumb, “tactical” leg holsters. I wanted a cross-draw for hunting. I found a local guy who made this one for me. Cost $100 and certainly worth it.
