|I gave two stars despite the cartridges' fragmenting well and not over-penetrating my drywall targets because of critical feeding failures.
I live in an apartment building and worry about a stray bullet passing through a wall in a home invasion situation. I'd heard that frangible ammo would fragment and have a lower probability of passing through drywall intact, so I picked up a box of BVAC frangible cartridges and brought them to the range to test out.
The used brass all appeared in fine condition, and only 2-3 out of the 50 rounds I shot passed completely though my homemade double-layer drywall targets (two pieces of drywall, separated by 4" of empty space).
However, there were many, many failures to load and stove-pipes--perhaps as many as every 2-3 rounds. I was using a fairly new and well maintained Sig P229, and have had no trouble with any other ammunition--even after hundreds of rounds. Failure to properly cycle is a potentially life-threatening problem for this cartridge, and one that has put me off from using it in a self-defense situation, despite its impressive ballistic performance.|
