I don’t mean to seem dumb after 25 years in the army, but I am finally going to buy a rd impact mkII, want a 30 cal but see they now have a 35 cal can someone help me what is the big difference between the two in killing power. So will the 30 cal kill the same size game as a 35 cal or do I need to save up more money. No one on YouTube seems to talk about this kind of stuff. And no one is showing anything about the 25 cal avenger adjustable regulated cheap pcp please don’t mind the spelling I am a soldier of the late 60s. Thanks everyone.
