With the proper handloads, what kind of accuracy can I expect with a 6" barrel, factory iron sights and off of sandbags at 100yrds. If you have any specific loads, I would be glad to hear that also.

I own several securiy sixs with good loads 6 inch groups should be doable if you can do your part.

I won many police revolver matchs with mine back in the day when I carried one for work.

I carried a six inch back packing loaded with hard cast 160gr swc's at 1300 fps for years.

Now carry my Ti 41 just because of weight.

I really like the security six to bad ruger stop making them.

Thanks p dog. I carry mine loaded with 180 gr hard cast in front of 12 gr of 2400 as my sidearm when hunting or just trekking. I don't know the speed but it has authority!

I bought a Security Six 6" blue years ago and put it up to play with. Forgot I had it and bought a 6" blue GP100 last year. Got the two out and looked them over. The Six is much smoother feeling.

I shot a security six in PPC competition back in the 70's. I think that 6" groups at 100 yards are possible, maybe even 5", but would take a lot of load development and practice in order to achieve groups of this size on a consistent basis. IMHO 7 or 8" groups would be excellent.

Super, I have two, one 4" stainless, the other 6" blued. The 6" is a real shooter. It will shoot 1 1/2" groups at 25 yards all day long. It's been a long time since I put it on paper at 100. I think it would do 6" at 100.

It likes 2400
CCI magnum primers.
Nosler 158gr hollow points.

I think my load is above what's listed in the modern manuals, so lets just say it shoots best close to max.....I just won't say on which side of max.....

I've tried alot of other bullets in it, but none will shoot as well as the Noslers.
