I was just wondering how many fouling rounds do you need to shoot to get your gun back in to zero or good for testing
And how many rounds do you clean between the next cleaning
And how many rounds do you clean between the next cleaning
I feel that I have lap/fired broken the barrel very well as my gun shoots good but I have to shoot a handful of slugs before it starts grouping better againFactory Lother Wather Texan barrels very greatly.. Before I hand lead lapped my .510 Texan barrel..You needed to clean every 3-5 rounds for any kind of accuracy... It was horrible... Know that its smooth and uniform it doesn't really lead anymore after aggressively hand lapping.... So I can go 40-100 rounds and accuracy doesn't suffer... Airgun s need perfect smooth u inform barrels....Rough barrels do t work with soft cast lead...
I use powder coating and lube...After cleaning first shots off.Then it settles down.. Maybe trying going up a l in slug bore size..My barrel is 5.105 after lapping was .510.. So a lil more bore diameter... Your barrel has to lead to tighten up......MaybeI feel that I have lap/fired broken the barrel very well as my gun shoots good but I have to shoot a handful of slugs before it starts grouping better again
Thank you for the infoBarrels usually have to be "leaded" or "seasoned" per each different projectile. JSB 25.39gr pellets for example will not leave the same leading as a 26gr slug.
With my guns usually 4 or 5 shots will do it if I change projectiles, which I don't.
