Thanks, I will look around.

I'm a very big fan, and owner, of Ruger's.

I could blather away but to complement a cogent response please see this informative dissertation:

Just to rehash some matters to contemplate.

* Consider your barrel length when calculating velocity and pressure.

* Determine bullet diameter vis a vis groove/barrel diameter i.e., interference fit and the amount of obturation, squeezing it takes to push the bullet out the barrel.

* Consider bullet type, construction i.e., solid mono-metal, bullet Brine hardness.

* Stay within the burn rate chart limits and recommendations for your particular application. That is usually about 10 numbers/speed above or below the best pinnacle of effectiveness.

* Usually rule of thumb is that the heavier bullets carry more energy and punch than the lighter weights/grains.

Looks to me like you have already received a super abundance of advice from some very experienced and knowledgeable owners/users so my input seems superfluous.

Whoops, I messed up, hit the wrong key.

270 gr., not 170 gr. Thunderheads. I just saw that reviewing this thread.

Not a gun writer for sure, but..........for what it's worth in regard to the throat diameters in newer 45 Colt Rugers. I have one of the newer Redhawks, (manufactured in early 2015) and have slugged the cylinder throats. My caliper says they are .452+. My tool only measures to thousandths, so .452+ means a hair over .452. Cast bullets run through a .451 sizing die shoot fine with virtually no leading.
