Thanks for the replies, I was going to get a 410 but was put off with the size of cartridges and possible range and was told that if you use the 3" magnums to gain range etc then you loose the effect of the mod.
What are "sub sonic" catridges, as I have never heard of them?
Does the 12 bore moderated work well then to silence the noise as well? .
cheers for the help
