Thread: 308 blanks

Hi
I've been making some good progress with the 22 in gun training my pooch. I can now shoot it right next to him and he doesn't flinch. He's still not excited or anything about it being shot so it's probably time to get him out shooting some rabbits just so he gets excited by the sound of the gun to make the transition to a 308 a bit easier..

Anyway, I was just wondering if anybody has had experience shooting 308 blanks rather than live rounds to get the dog used to the big gun? Will they ruin my gun? Are they as loud as a normal round shot into the ground?
Cheers
Tom
