Dot size for 22 cal Hunters Pistol Silhouette

[nitecapt]

I have just ordered a Volquartsen Black Mamba and plan on outfitting it with a CMore Railway sight because the dot modules can be changed depending on what the use is. I would like to shoot steel and also silhouette. These would require different dot sizes based upon target size and distance. I will use 8 or 10 MOA for steel but I am a little perplexed on what the proper MOA dot size would be for the silhouette. The smallest dot that they have is 2 MOA.
Also, if I sight in with a small dot and change the module to a large dot, does that require a re-sight in?

Any input on what the best dot sizes would be would be very much appreciated.
Thank you
Ray

Most red dot sights can change dot size with a knob. Those railmasters are really designed for action pistol shooting at very close distances. A 2moa dot is not even close for silhouettes- you need more like 1/4 (i use 1/2 and at 100yds its huge)

Interesting, I couldn't find any by googling it. The Vortex doesn't but most of them do change dot "brightness". Are you certain?

The one on my s&w 41 changes sizes, colors and even shapes from dots to crosshairs to triangles. It wasnt an expensive one for sure. I have another one that was even cheaper- i think its an nc star- and it does the same. Looks like youre looking for a better unit than the el cheapos. If i used them for more serious work id do the same i guess

The Ultradot Matchdot (version 1 and 2) both have variable dot sizes from 2 to 8 MOA.
