From solid to hollow-point
Reading John Hill’s article on case preparation (Australian Shooter, August 2018) reminded me of a problem I encountered but ultimately solved. I was given a large amount of 5.56 ammunition but when I fired some in my .223 I experienced considerable pressure signs.
I researched online and discovered the 5.56 has a far more elongated throat compared to the .223 so I checked the overall length and re-seated the projectiles. Now I had useable cartridges but they were solids and no good for hunting.
I carefully ground off the tip to reveal the lead, drilled a small hole to 6mm deep and now I had usable hollow point ammunition. They work well on feral pigs and really open up on foxes.
