Like walkalong, I also like a 255 gr lswc with aa#2. I just don't think you need more than 900fps for full penetration with a heavy 45 cast bullet and this is within reach with medium pressure loads with #2. Your mileage may vary. I keep round nose rounds loaded below 14k for safety. All my lswc rounds are Ruger only. Keeps life simple.
Looking for 45 Colt pet load.

I too am reserving the round nose bullets for the SAA clone but would note that those bullets I picked are also softer than the semi-wadcutters used in the stouter loads.

I use coated 250-gr lead, with 6.2 gr. of Titegroup. Works great in my Uberti Cattleman. Burns clean, very little fouling. When I went down to 6.0 gr., it started to get sooty. Other powders I tried were even more sooty.

Dog Soldier I use AA5744 for 45 Colt as well, which we have talked a little about in the past. I get a lot of unburned kernels in the rifles that I have used it for. Do you see that in your pistols?
I have no doubt it does at .45 Colt pressures. A 100% fill of AA-5744 in .357 leaves kernels even at that pressure. Or are you loading 5744 at Ruger Only levels in .45 Colt?

Fill the case with just enough real BP to give about 2 % compression under a 250 or 260
cast boolit. Same bullet with 7gr Herco shoots clean through 2 does side by side at 40 yds. Keith style boolits are awesome.

I must be the only one who uses greendot? as I load 6.8gr greendot with a .457 dia cast bullet lubed with lee alox and its super accurate!!

What would make a .457 diameter bullet a good idea?

I am in the process of finding a load for the lyman 452423 bullet(mine is 245 grain with my alloy).

Lyman's Cast Bullet Handbook has guidance for similar bullets in 250 grain, Lyman #2 alloy. Looks like they had best results with Unique at 6.0-8.5 grains.

realgun I have two heritage big bore revolvers and they kept leading with .452 and so went up to .454 but still had leading so I then went up to .457 and the leading totally stopped! and infact accuracy came way up and so in these pistols they shoot this oversize bullet really well! so I tried this oversize bullet in my two rossi 92 leveraction rifles and didn't have any leading and can hold very tight groups!

There is some important context with that bullet size, it seems. Not disputing the good results, but I wonder what hardness you used in the bullets and why the bullets apparently were not previously bumping up in the rifling, sealing off gases that would otherwise melt the bullet. I also wonder about the throat size and how such a bullet size would pass without making a mess of the forcing cone. My point is that I am guessing that not just anyone should follow the example without understanding all the variables.realgun I have two heritage big bore revolvers and they kept leading with .452 and so went up to .454 but still had leading so I then went up to .457 and the leading totally stopped! and infact accuracy came way up and so in these pistols they shoot this oversize bullet really well! so I tried this oversize bullet in my two rossi 92 leveraction rifles and didn't have any leading and can hold very tight groups!

I get excellent accuracy with this oversize bullet infact when I used the smaller dia, bullets the cases when fired would have a small swell at the back of the case when shot out of my rifles but once I went up to the oversize bullet the case swell went away how strange! seemed like it had less chamber pressure with the oversize bullet as compared to the smaller bullets! I also use wheelweight lead for my bullets at this time! so bhn around 12 or so and works very well!

I understand obturation, i.e. sealing of the barrel ahead of the blast, to be critical in reducing lead fouling. Yes, there are other variables there too. Lack of obturation I believe would make the load inefficient.
If you have large throats, as midland man must have in those revolvers, you'll need larger than the norm cast bullets or a soft one than can bump up to seal (obturate) the throats. That same soft bullet could easily squeeze down if needed as well. Fit and hardness are both important. I want both optimized if I can get it.

I can tell you this in both my rifles and pistols this oversized bullet performs very well and holds tight groups! and the bores are very clean plus I have read were heritage supposedly made the bores to the original dia as the colts back then when they made them with .454 dia bores so I wonder if that's why the bigger bullet works so well? plus my rifles have .452 dia bores but perform with this oversize bullet with excellent accuracy!

I am loading AA5744 at pretty low levels and only with lead. I do notice unburned kernels in the barrel. The loads actually shoot pretty nice.

255 grain lead and 8.0 of Unique has been pretty much a "standard" for well over 100 years.

Same here. 40 grains volume(2.5cc) of 3FG Olde Eynsford and 250 grn Big Lube. Thumper on both ends!

Are you guys really using AA5744 in the 45 Colt? I use AA5744 in the 45-70 but never considered it for the 45 Colt. Where did you get load data?
RealGun

Western Powders own load data includes it in the copy I made.
