Sorry I'm late to the party. I've been shooting steel matches fo a long time. What I show below is what my wife and I have been using in matches.
Recently I decided to buy a 1022 at a Black Friday sale and try it at steel matches. But I needed a red dot for it. So I have a cheap ADE red dot I bought from Optics Factory that's been mounted on my Marlin 1894 .44 mag for a while and it hasn't given out.
It has a nice sharp round 5 moa dot. It was well worth the $44.00 I paid for it
This is a J Point 6 moa on .22 conversion
This is a 8 moa C-More on a .22 conversion
My Spikes dedicated.22 has a C-More 8 moa dot
My wife's dedicated Spikes .22 has an older 6 moa Tasco Prp Point
