RE: Shot some maxi hunters/ need helpwith nipple
Sounds like the maxi is the load to go with.
I know of only 3 thread types for nipples(there are probably more but I'm not sure). the CVA's use 6x1 metric, some use 6x.75 metric, and some use 1/4-20tpi. I'm sure others will chime in on which you may have and if there are other sizes available.
