Eddie, Walmart in Danvers MA. What Walmart are you visiting with a good selection. Danvers has Crosman & Gamo mostly .177.
That would be Stalwart...Well the .22 lr is very seasoned... read very well polished & worn rifling... plenty for up to 60 fpe tho... Eun Jin should do excellent and have some molds... The .22 WMR is unfired and it needs lapping... rough and catchy right now... will probably fire lapp with some 10-20 micron diamond paste or similar bore grit... then some 7 micron finishing with JB bore paste...the Wheeler 600grit (~30 micron) is to course imo...Have not ran into a leading prob in a microgroove barrel but most of us stayed with standard velocity rounds... My ex Has her dads still... Point is in a .22 sub sonic air rifle you should not be getting much leading...except if you have a rough barrel... even if you have a choked barrel leading should only happen if the choke has a rough spot... like machining artifacts from drilling...even the hammer forged barrels should be honed to final pre hammering size, to prevent transfer to the bore of any machining marks...Heym does TJ liner and BSA do not hone I think... so yeah it will depend on the barrel some will need some help others not so much...
