Just got back from it's first trip out.
I ran out to a small range we have at my brother's house, nothing fancy and I had to use a milk crate as a benchrest.
I was shooting Magtech .38 Special Cowboy Action Loads with a 158gr Lead Semi Wadcutter.
With this load, the gun shot about 1.5-2 inches to the right and about the same low, but very consistently.
I was firing 5 shot strings.
1st target
Last target, I was beginning to learn to correct and my groups got a little better.
Of course, I could not resist doing the playing card bit!
4 shots on the card, with the 5th going high and left.
It's been 15+ years since I shot a SA with fixed sights, so I got room for improvement for sure, and some playing around to find the best load for this one, but I had fun!
