Loading Lead in a 44 Mag ???

[Big joe]

I have a Ruger Redhawk in 44 Mag and have reloaded a lot for it with jacketed bullets. I would like to start reloading lead bullets and I purchased 500 lead alloy 300 gr. bullets for it. These bullets have no gas checks but I was told the alloy was VERY hard and that I could use regular jacket bullet data when reloading. Several questions here... Can I use jacketed bullet data?.... Can I use jacketed bullet data to max levels?... Will increased velocity cause a leading problem? ... Does it help leading to fire a few jacketed rounds beteween lead rounds ?

I have never shot lead out of anything but my 38 special, but I would love to shoot my 44 Mag more without the increased cost of jacketed bullets. So, the answer to the above questions and any other information you think might be helpful for me would be greatly appreciated.
