I have been new to pcp airgun s. I bought my Texan during the pandemic and jumped in with both feet. I was in my younger days a long range powder burner hunter Benchrest and gunsmithing. I was very used to long range setup s and dialing elevation. After watching all the awesome long range videos on YouTube I bought my Texan. In short it has been a extremely difficult to obtain consistent accuracy. I shoot slot and that's what attracted me to airgun s. Cost effective cast slugs and air much cheaper than the powder burner alternative. My Texan breaks .... 300 lbs of slugs and two major issues... I bought a Texan for the reputation and accuracy presented online.. In short I need 2 big bores to have one working. So in my eyes Texan Tx2 valve not reliable... Umarex Hammer not reliable.. AEA big bores...not.reliable.. So.who really makes a good reliable big bore??? I haven't had experience with Western Bush buck or Hatsun piledriver or extreme big bores.. I making this post to help myself and new shooters getting into big bores. How many rounds of slugs without break downs. With powder burner bolt actions they never broke just wore out barrels. I want big bores to get better.. The quality of some of the barrels.on many of the big bores are horrible.. I would like the industry to get better.. More performance and less marketing hype. Thanks for bearing with me Airgun Nation friends..
