2 tenths of plastic wouldn't help me. I consitered steel, but I could never find anything thick enough. The most I tried was three quarter inch plates. After that i gave up. I think it is best not to miss.
BTW it was a 208 grain Hornady AMAX with about 99 grains of US869.
The chrony didn't have a chance.
Hornady came out with this recently (208gr A-Max). I had been hoping they would come out with a heavier Amax for a while. I was so excited I decided to finally start loading for my 300RUM. Hence the demolished chrony.
.30 cal hole from front to back... the screen now reads error..
:( Luckly I bought the Beta Master version so the replacemt parts are about 50 dollars.
To anyone looking for a cheep chron. I reccomend this option in case you accidently shoot it.
Also remember to aim high with a rile. Best to test on paper at that range to get point of aim.
