I'm loading .45 Long Colt anywhere from Cowboy mild up to maximum loads using .452 sized cast alloy bullets. I want to try .454 sized bullets in my gun (Ruger Blackhawk) to see what kind of accuracy difference there is. Wanting to be carefull, I will start with the mild loads, however I was wondering if anyone has any thoughts or experiences on what kind of pressure increases I might expect, keeping all other variables & components the same.

RW2. See if your .452 bullets are a snug fit in the cylinder mouths of your Ruger. If they are loose, try .454 bullets. The ones with the snuggest fit will usually give you the best accuracy.
I feed 3 Colt SAA's and a Ruger Blackhawk,(old model) and settled on .454 bullets just for simplicity's sake.
For some great info on loading your Ruger, go to ( There are some really good articles by John Taffin, Paco Kelly, and John Linebaugh. Also there is pressure tested hot loads for the .45LC.
