45-70 got a scope now, 2X7 leupy, front site was so big i couldn't see a pig behind it. .450 does not have iron sites, put the first scope we took off the .450 on my .405 seems to work ok so far,so far I have shot 43 pigs with the .450, 27 with the .405 and 6 with the 45-70 I have not really warmed up to the 45-70 yet. .450 and .405 way out shoot the 45-70. as for a ar shoot out I am ready when ever you are. don't have a .22 anyway. rio7
