What To Try Next For 9mm Accuracy
I took sixteen rounds to the range...all I had.
I shot from ~25 feet. My group was about six inches and all over the place. Much of this is me as factory rounds are about three inches, but a tighter pattern. I am shooting for the first time in years. I am not certain, but I think there may have been some key holing, but not every round.
127 gr Lee 356-125 RN
4.5 gr Ramshot Silhouette
1.086 COL
The bullets came out powder coated at .359-.360 and my barrel is .354 so I ran them through a Lee .356 sizer die, but they came out .355
There was no leading and no powder coat residue, but there was a yellow residue in the chamber and barrel that I believe was powder residue that wiped out with a single pass of a dry patch.
After using The Internets I saw try larger bullet, more powder, and reduce crimp.
My plan is to try another grain of powder first as that is the easiest along with checking my crimp which did not seem over done and was not swaging my bullets.
I am also going to try my Aloxed bullets that are closer to .356 unsized. I would have to open up my sizing die to size my powder coated bullets larger than .355.
What are your thoughts?
I cannot try anything until my press gets back from Redding, but I want to have a plan.

What level accuracy are you expecting from a sub compact (3") barrel? I mean, your close to derringer country with that length barrel.
What factory ammo are you using?
How many rounds have you run through the gun? Some need a couple hundred rounds to break in.
A more reachable goal might be minute of belt buckle.
Great points. I have only shot 116 rounds: 50 Federal ball, 50 plated 124 gr, and 16 powder coated 124(127). Of the first 100, the majority were in a 3.5 inch area. If I can get that (or even 4") I will be happy as the gun is for eventual CCW and 25 feet is the longest shot I would feel comfortable taking, and then maybe only in certain situations. Of course I have to qualify for CCW and I do not know what distance those targets are. I do not currently own a chronograph.
