They also have some blue dot loads

While data for lead is similar,and you may not be too far out, I would never counsel someone to go outside published data without in depth knowledge and that includes a gun capable of handling a higher than normal pressure. I use old SXS Guns from before WWII so I am careful to not get carried away
