Yes I do. The larger cylinder works much better. The cylinder does get hot, so when I'm sizing 500 or more, I wrap a wet paper around the cylinder to help keep it cool. This is much easier on the arm and shoulder than pulling the handle.
As for the Master Caster, it is working great also. This is a worthwhile mod for anyone who load a lot. I can cast over a thousand in less than 3 hours and not be exhausted when finished. My neck will start to tighten up sometimes, so I just get up and take a 10 minute break.
A little off topic but related:
I ordered a new .380 mold from Accurate and it casts a beautiful boolit. After casting over 1000 I decided to coat them with my usual Hi-Tek coating. After loading few I discovered my G42 does not like this boolit. It jams straight into the feed ramp and stops. If I hit the bottom of the mag it will feed into the chamber and the rest of the mag feeds ok while shooting. The new boolit is a 100 grain truncated nose without lube grooves. Adjusting oal has no effect. It also seems to do this with a Hornady Critical Defense. At first I thought it was the old versions of the magazines, but it also did it with the newest 03 versions. I may sell this new mold and get a round nose non lube groove mold. I have no trouble with the round nose boolits.
