I have loaded and shot over 100 of the 308 subsonic with a 20 gr. Berger .17 in the cavity and have had good success on deer.
I was able to locate 3 of the recoverable bullets this season and have included a picture (with the penny for size reference) as you can see, one shed all 3 petals and the other 2 lost 3 of the 4.
My loads were over 8.6gr. Lil'Gun with Magnum Small Rifle primers-CCI.
All were shot in a bolt action with 16 1/2' heavy barrel and suppressor.
The velocity is borderline sub/supersonic as one in 3 will crack the sound barrier but accuracy is so good that I live with it.
Does not seem to spook the deer though I must say we have large numbers of stupid deer around here.
