Re: problems with bergers
I don't want to be a downer here, but truth is, if you hit that doe in the killzone she'd be dead. Even if the bullet failed to mushroom or fragment at all, if it went into the boiler room, she would not live that long.
My guess would be that you went just a tiny bit low and likely hit the leg but didn't hit bone causing only a muscle wound that would eventually heal up.
I haven't shot many animals with Bergers, but they've still never failed on me.
When it all boils down, caliber, sectional density, ballistic coefficient, bullet weight and construction, velocity, etc. all put together don't matter half as much as shot placement.
As long as you poke a hole in the right spot, the critter will die, as the dozens of cattle I've killed with a .22 LR have proven.
