You would be suprised some of them don't crack as loud as the numbers show . i shot 3 or 4 rounds of raptors and they were in the high 1400s and one made 1510 now that sounded like a 22, they say it want hurt these nitro piston ags but it seems like dry fireing them i personaly don't like them. You can go back about 4 pages and see my chrony results and one mountain made a nice chart with the results iI don't seem to have enough sense to do that. But these are fine rifles and they shoot very hard. thanks david
