been working on this awhile. thought i had it solved but I finally understand what no lead means with a recent try of trailboss.
noe 429421 hp acww drops .4335 at 233 grains bhn 9 sized .4314
gun is ruger sbh 4 3/4 44 mag
firelapped and slugged .4292 bbl
throats .4304 to .4306
felix lubed bullets
shoots accurate with 2400, unique, trailboss, all under 1.5 at 25yds
when using tb a recent thing (no and i mean zero lead 100 rounds 200 rounds zero)
770 fps over chrony and if i could do my part i believe it would go in same hole.
lube making it to end of bbl and a little lube build up on forcing cone but 0 lead with trailboss at 770 fps. i have shot umpteen million and can run dry patch and have shiny bore.
using unique, 2400, 4227 anything that goes past about 900 fps lead rears its ugly head down the rifling. i have checked for tight spots, fire lapped and can't feel anything. what do you guys think is going on? bore looks incredible when clean.
please help. i have put alot of time in this project and have an incredible plinking load but now i see what no lead means with tb load how do i get it with full pressure or even moderate loads?
sorry for the rather long post.
should mention i have tried water dropping with no change in leading
