The chamber throats on Marlins[lead] needs to be altered to get better accuracy.Never liked micro-groove rifling on any gun.Savages are all good shooters ....................nothing against the .22mag but you can load load centerfire varmint rounds cheaper and get better performance..........loaded up or down....................Harold
I agree with pioneer 2 that a good idea would be to reload a centerfire 22 which would be cheaper and you would get alot more velocity out of it to than a 22 mag obviously.
