Um... guys, I'm not sure some of you read the original post completely. Advice to firmly crimp .44 mag loads when using slow powders like H110 and 296 is good stuff, but he's not loading H110, 296, or even Blue Dot--he's loading HP-38 which is a relatively fast powder, and not even remotely close to H110, 296 or Blue Dot in behavior. Strong crimps are necessary with the slow powders to help them ignite and get a good, consistent burn, as well as to prevent bullet pull. Since he's making light loads using a fast powder, he doesn't need the same crimp--only that which is necessary to prevent bullet pull. The question is, how much crimp to prevent that bullet pull?
Renaissance, I guess I would suggest at this point that you experiment with progressively stronger crimps to discover what it'll take to keep the bullets in place.
