I have so far loaded up about 200 of the 240gr .44 SWC bullets and didn't have any issues other than a little wax/lead to trim off at the end before crimping. I chose to pair it up with good mag primers and trailboss. Have not shot them yet or I would go with 5 stars but they seem legit.
The 125 grain RNFP bullets are the most accurate bullet I've found for use in my revolvers (GP100 and 642). As with most lead bullets, you'll get lube buildup in your bullet seating die and the revolvers cylinder, but a little elbow grease solves that problem.
