I've been hanging around for a while and have gained a lot of knowledge reading the posts. I have two 10/22's. I have a wallyworld model in stainless and a target model in stainless. I have replace trigger,hammer and sears. I have also added mag release entensions and bolt releases as well as bolt buffers. Still trying to improve my groups at 50 yards. Have anyone installed a bug hole tuner and what is your opinion as to how much it improved the groups. I've read the threads on bedding, but it looks like the right amount of pressure at the right location would stabilze the barrel. Thanks and keep the info coming.
