I have been playing with my Standard Manufacturing 45 Colt.
I had pretty good success with a 250 gr RNFP bullet over 8grs of Unique.
I am now trying out my 270SAA mold that drops bullets at 288grs over 8.0 and 8.5 of Unique. The gun hits about 5 inches high to POA at 25yds with these bullets and this load.
Would you drop down to 7.5grs of Unique or try a different powder? I'm thinking of 10grs of HS-6 or 18.5 of 4227.
Opinions wanted!
Thanks

I think you need to get it going faster if you want the point of impact to lower. Five inches sounds like a lot. You may need a taller front sight.

Thanks ***** About the best way to lower POI (Point of Impact) is to shorten BARREL TIME. A lighter bullet is a low pressure route to reduce barrel time. To put it country simple, barrel time is the time elapsed between primer detonation and bullet exit from muzzle. Recoil begins while the bullet is in the barrel. Which is why variations in grip invite fliers @ 12 o’clock. And why individual velocities from a heavy bullet load may correlate directly to vertical Point of Impact, with the slowest bullet printing highest; the fastest bullet printing lowest. I would not try to lower POI by raising velocity, and certainly not with your gun. I would DEEP SEAT a lighter bullet over a starting load of fast powder. David Bradshaw

Try it out to 50!

MY RECOMMENDATION IS TO STICK WITH THE 250gr RNFP AND FORGET THAT HEAVIER BULLET. JUST A "FEELING" FROM A BUNCH OF SHOOTING, I BELIEVE THE 250gr RNFP IS WAY MORE ACCURATE THAT THE 270SAA, AND BTW, I HAVE ALSO FOUND THE 250gr RNFP TO BE A VERY GOOD KILLER. OVER THE PAST 140 PLUS YEARS OR SO TONS OF GAME HAS BEEN KILLED WITH A 45 COLT 250gr RNFP TYPE BULLET.

I agree with 45MAN, particularly since you don't mention a problem with that load hitting high. One of the loads I use in all my 45 Colts is that same 250 RNFP with 8 gr. of Unique, and it has been nicely accurate. I do also use heavier loads on occasion, but only in the large frame Ruger Blackhawks. I would never do so in SAA clones, despite Elmer.

Thanks Hows your trigger lighter trigger usually helps if you are on the heavy side ?

I would stay with the classic 250 gr slug if you're happy with it, if not you will have to replace that front sight with a taller one. The heavy weight bullets can accelerate wear on that fine 45 that you have, better leave them for the Rugers & FA guns.

David walked me through the issue of hitting 6" high @25yds several years ago on my EL Dorado 44. My rear sight was bottomed out and I really like the EL Dorado original as possible.
I dropped from around 250g to 180g and increased the velocity. That brought it down 5" at 25 yards. If I were you, I would try this just for the education.
Some of that drop might also be from following David's other advice about Follow Through. I know that really helped on consistent accuracy.
However, I'm still thinking about one of 2 Dog's front sights on a regular basis. I really don't like building rounds for one gun and keeping them separate. I also much prefer the heavier bullets. They just seem to sing louder, like sinners at church, when massaging steel gongs.
