RE: Finally got to shoot my new Lymans
Id heartily agree with the other posters about the nipple being a possible problem...
Iffen the cap doesnt seat all the way down on the tip of the nipple its a crap shoot iffen *any* cap will ignite at hammer fall. Another possibility is that the hammer spring might be weak or the lock a tad tight at the hammer...
Before I got into the lock I'd be inclined to try sanding the Od of the existing nipple , another nipple or even other cap brands as not all #11 caps fit the same...
Im personally kinda partial to the CCI #11 mags and either an Ampco or a Hot shot nipple on all my hardware.
Keep yer powder dry,
