I've owned a good number of different .22 rimfires over the years but nothing that anyone would consider "top shelf" so I never really gave much thought to wringing any real accuracy out of them.

I have a brand new sweet Savage MKII Classic .22lr with the Accu-trigger coming and a beautiful Leupold VXII Ultralight 3-9X33 EFR scope to top it off.

This is going to be a relaxing squirrel swatter but I really want to get it to shoot it's best.

Every centerfire rifle I've owned I took the time to hand lap the barrel myself right out of the box before the first round was ever fired and I have some pretty sick shooting big game rifles for the effort.
Should I do the same with a high end rimfire to remove any factory machining flaws or is it not necessary?

What really IS the proper way to clean a good .22 for promoting the best possible accuracy? I've always just done the usual solvent and patches for all my plinkers but never really worried too much about lead build up.

The Savage MKII Classic has a 24" button rifled barrel.
