As rodwha pointed out 777 is pretty finely grained... Finer then 3f at any rate.. And I use it almost exclusively.
I DO want to "magnumize" my guns in fact... well sort of... and frankly I dont see a damn thing wrong with that!
Where I live we have a LOT of issues with black bear, including a LOT of "run ins". These are BLACK bears, and having lived out west I am well aware that thats a lot different then grizz... But we ARE also having some serious problems, like one guy last year that was literally picked up and thrown off his own porch when he walked up on one eating out of his cats bowl. My best friend in this area went out one morning, half asleep with coffee before work, and walked dead up on one on his back porch. He QUICKLY learned to keep his trash ELSEWHERE before he could make a trash run LoL. We also have hybrid hog here. REAL hybrids. If ya check, the largest records are always from eastern Tennessee. We had them as far north as Abington. Abington is a 45min tide from here, but that includes "out of my way" drive time, it would probably be 20mins as the crow flies. The reason for the records is that some are true Russian boar and most are bread with em... Nasty ass critters to say the least, and VERY dangerous.
I have loaded up to 38grs of 777 in my remmis and the only problems I have faced so far is some gas cutting on the arbor from practicing that load too much. I reduced how much I practice with it by using multiple cylinders. Yes, I have center fires if I KNOW Im going into the bears living room, but these days I usually dont and I almost ALWAYS have one of my BP on me.
Look, thats what DREW me into the whole BP revolver thing in the first place. If i WANT to shoot mousefarts, then I can LOAD for that.. But if I want to make sure Im loaded for bear, or hogs, or meth heads, then I can load for THAT too... Im basically handloading each and every round without ever having to invest a thousand bucks, and room I dont have, in hand loading equipment.
That being said, I also want to know just HOW much my guns ARE capable of, and want the wiggle room to use that much if the situation calls for it. Unlike others here, as a former bear hunter, I am damn sure NOT about to go up against a bear or monster hog with ANY BP sidearm if I can get OUT of it... But since its what I will most likely HAVE, if that day ever comes, Id also like to have the best chance that I can.
