My son has recently started shooting a 44 mag. I want to get him into reloading using my circa 1970’s RCBS equipment collecting dust in the garage. It’s been awhile and my experience has been with rifle loads only, ie. no crimping etc.
I bought some Berry’s 240 gr plated HP bullets and Bluedot powder. I couldn’t find any data at Berry’s online, (my handbooks don’t list plated bullets, need to get some new ones) so sent them an email for some info., there response is below.
Sorry, we do not have our own tested load data, but let me try to help you.
IMPORTANT NOTE: All of our standard caliber copper plated pistol bullets share only two limitations - Which are : NO velocities over 1200 FPS and No heavy roll crimps.
We also point out in our print catalogs & on our website that our 44 caliber bullets are not designed to be used for full Magnum loads.
I did find a load for you in Speer # 14 - as follows - 240 GD-HP with 12.3 Gr. Blue Dot for 1186 FPS - which will be within our velocity limit, but avoid any heavy roll crimps.
I used the above load because Speer also makes copper plated pistol bullets - with the designations of TMJ or GD-HP - Their copper is thicker & their price is higher.

So does this info seem reasonable to you experienced reloaders? With reduced loads and Bluedot powder, do I need magnum primers? The bullets do not have a crimp ring. Do I still do a light crimp? Are there any drawbacks using Bluedot powder with light to medium loads?
Thanks for any help.
