I currently load the Remington 210gr SJHPs with 5.7gr of Green Dot for a target load in my Ruger Super Blackhawk (standard primer). I actually use them for shooting during league night at my local indoor range. They're consistent and provide light enough recoil to allow me to re-acquire my target quickly during rapid fire strings.
I like the 210's, but they're not available 8 months out of the year. I need to change out the 210gr for the 180gr SJHP due to availability. I'd like to keep similar performance, but I'm a little fuzzy on my logic.
My manuals always always show a higher powder charge with a lighter projectile. I'm guessing that's to keep the chamber pressure close to the max and get the bullet to perform at its maximum. But the other side of my brain tells me the projectile is lighter and needs less oomph to perform that same, thus needing less powder. The one thing I fear is underpressurizing the chamber and sticking a bullet in the tube or worse, creating a grenade.
Can anyone give me an idea which way I should go with the charge on the lighter bullet?
TIA
