Barrel Leading
Posted: Sat Sep 10, 2005 10:49 pm
EDIT-NOTE: see end of thread, S&W replaced the barrel.
OK, I'll show (more of) my INexperience...
I was at the range (new membership, convenient to the house).
and took my SW 22A-1 (didn't want to risk my 22/45).
I took some misc. .22LR to just "shoot" and get aquainted
with the range... Shot a couple-hundred rounds of some old
coated-Federals and they were just fine. Then I was going to
finish-off a brick of Rem:ThunderBolts that didn't shoot well
(actually very poorly) in a rifle several weeks ago...
after about one Mag of Rem:TB, there was NO-grouping,
off the paper and "tumbles" and fragmenting (paper-cuts
were not Holes, they were slices)... Well, I attrributed it to
the TBs... after I got home and inspected a little closer
my barrel is now Lead-Lined, SuperBoy would not be able
to see inside to inspect it!
I presume I should not use my long (dental-type) picks to
scrape the lead out of the grooves...
Am I EVER glad I decided to NOT take my Ruger or BuckMark!
I have my powder-solvent and lubes... but never bothered
to consider Lead-Solvent/cleaner... What Works ??
ThunderBolts are not THAT-BAD of a cartridge...
Is serious leading more of a barrel-problem ?
too tight? grooves-too-high? bullet going down the barrel
too FAST or SLOW to get in the grooves ?
or just a Lead-dia vs Barrel-dia mis-match and don't use
those in that one anymore... -thanks
