I just got this from sportsman's guide. . .

 

(here is the link from BSA . . . http://www.bsaoptics.com/product.aspx?p ... ductID=113) - I guess I should have looked here first.

 

On the SG website it said "15 studs for popular calibers ranging from .177 to .50 cal. ."

 

Now that it arrived the studs included are;

.17, .22, .66mm, .25, 6.5mm, .27, 7mm, 30, .32, .338, .35, .375, .44, .45 and .50

 

 

No .308? No .223? Aren't those pretty popular?

 

I didn't mess with it to much, but I guess I can use the .22 stud for the .223? Any idea what is close to a .308?

Chad the .22 is for .223 and the .30 is for .308. The arbors expand.

BTW .22 nominal bore diameter is .223-.224" and .30 cal is .308. So, you should have everything you need.

 

Frank

I do have the same one Chad, for the price, you can't go wrong, its works ok, it get you close enough for the final sighting in at the range

 

308 is 30 cal..

223 is 22 cal..

30-30 is 30 cal

7.62 is 30 cal

 

380 is 9mm

Thanks fellas. Big help!

 

Frank, the only one that seems to expand is the shotgun arbor. Maybe I'm missing something?

Chad. The end of the arbor closest to the breach doesn't have petals on it to tighten up the fit in the bore? Sorry if I misled you.

 

Frank

Nah, just the shotgun one does. There is a "arm" that is supposed to hold tension to prevent the unit from spinning, but of course that doesn't work to well either.

And there's no thread on the breach end to tighten up that leaf? Weird...

Exactly, I thought it was weird as well. No nothing...no threads at all. :x
