At least that is what my 50 yd long line shot group looked like.

I am shooting a Springfield Armory 45 1911 with match grade barrel, sites, trigger...the works.

At 25 yards nice tight groups with 185 gr SWC w/4.0 grains of Bullseye. But at 50 yards, the shots are all over the place. Looks like a shotgun patter with nothing close to the center and that is from shooting off a rest.

Recommendations, thoughts?

Got to the 230gr bullets. My SA 1911A1 won't group at range with anything lighter than 230gr. 200gr cast start opening groups at 25yds and 185gr jacketed begin loosing it at 20yds. Don't back the loads down any either or this will also cause accuracy losses even with the 230's. Mine is a standard out of the box gun, just added a compensator. It doesn't care much which particular powder you feed it as long as the load gets the 230gr bullets moving over 860fps before they clear the muzzle. Powder I've run (that I can think of at the moment) Red Dot, Green Dot, Herco, Unique, Bullseye, Blue Dot & AL-5. Unique shoots well till it starts crapping up the gun then accuracy will fall off. Bullseye is the most economical as in loads per pound, it and AL-5 are the two cleanest burning powders too. Cast or jacketed, doesn't matter either, I run my cast from strait WW alloy, bullet shape doesn't matter much either RN, TC & SWC all produced the same groups, maybe it you clamped the gun in a rest it would show some difference but from the bench holding by hand, can't see it.

Are you shooting these from a Ransom rest? Or off sand bags.
In my experience, my 45 Gold Cup shoots wonderfully the closer to the target I get. When the Gold Cup doesn't shoot well it's usually the jerk on the trigger.

I am shooting off sandbags but not even a relatively close shot. I am tyring to get into Bullseye competition and need to figure out a reliable 50 yd load.

Go to a 230gr bullet and push it with 5.0 to 5.4 grains of Alliant Bullseye and you'll likely see a marked improvement in accuracy.
