I live in the coastal NC area we have all kinds of no legs slithering around & I`ve found this loading to glue em to the dirt , dead rat now!
when ya first shoot this load it`ll seem benine at first ,pattern it , but it`ll do the job , I shoot it from 4"& 6" revolvers .
If it`ll penatrate an aluminum can both sides it`ll put no legs to sleep, 15ft I would say is max effective range
1: anneal mouths a bit ,not a lot.
2: prime with as hot a primer you have
3:you need a full length 222 rem sizer die, size the max case to the shoulder portion of the 222 die.
4: cut cards from cereal boxes or thick poster board ,I use 2 cards tite on 4gr of CLAYS
5:fill case with shot, I ran across some #10, fill to 1/8" ,leave room to place another card on top, run case into the 222
die a bit deeper, the shoulder portion will roll the mouth a bit.
6: seal with water proof carpenters glue
PS:
After firing the brass will fire form to the chamber & will hold even more shot!
Have fun ,Be Safe!
