Last time I LEOSA qualified, I used Federal 38G, in my S&W M640 No Dash. I had it in my safe. Couldn't get anything else.

Halfway through the course of fire, the rounds leaded the barrel so badly, that it changed the point of aim/point of impact.

I started shooting at the clock center and hitting the clock center. Then with the same point of aim, I started hitting at 11 o'clock. High and left.

I noticed immediately, and after two or three rounds confirmation, adjusted my point of aim to 4 o'clock.

Once again, I hit clock center.

Shooting fewer than 25 rounds, this load leaded the barrel so badly that they affected POA/POI.

Stay away from Federal 38G.

I have other posts here, over the years on the topic.

Just don't. My advice. Your mileage may vary.
