I'm in love with PCP.....Starting in.2020 I gathered up all.the message tools to.get started with airgun s...I watched all.the reviews.... First pcp TX2 Valve .510Texan....Second a Umarex Airsaber.... And what should of been first is a 22 pcp...I learned how to.cast slugs and powder coat them...Learned all about Airforce Texan...How to fix it....Learned how to hand lead lap barelsRough Texan .510 barrel a good.teacher..I have a Aqua environment 6000 psi external.regulator for.my SCBA tanks..I rebuild my Yong Heng compressor at least 5 Times...Learned alot.about compressorsGood and Bad....I.need something to.use less air....Also.it sucks.I live in Pa.and only 177 or .22 cal for hunting All after 3 years of watching and learning on the forums time for a 22 pcp...I.want a side lever or semi auto new awesome pcp that are on the market..... But I'm on a limited income. long term parts availability very important.... Also being able to work on .myself a must... So I bought a used Airforce Talon on the classified here...Having a stock on a Airforce a must for me....It has a Mad dog stock It also has a Altros Regulator A 20 inch barrel?????I'm hoping it's a custom TJ liner???? I.bought a Buck rail LDC for it$10.00 on the classified!!!!!! That was the only thing missing.... I'll. Probably shoot off of external regulator like my Texan...So when it arrives I'm going to remove and borescope the barrel....hand lap.for a lead.free smooth uniform bore....measure the inside dimensions of barrel...pour a lead barrel cast..figure out my desired slug diameter s...measure twist rate....Lastly order NSA slugs the right diameter... I know pellets just shoot...But I want to be able to shoot my home range which goes.to 125 yards..I want to buy a mold and sizeing dies and cast my own slugs in the future.. I should probably check barrel crown too...have access to lathe can re-crown and cut throat too ...I hope I'm not missing too many steps....
