Hello All, I'd like to share a link to some handy little items I've been using to keep powder coat where you want it and off where you don't when using the dry tumble with air soft BB's method.   http://search.eastwood.com/search?w=58038&ts=custom>http://search.eastwood.com/search?w=58038&ts=custom   If using PC for lube on bore riders these will shade the noses so as not to add girth.  If you like to use conventional lube and just need to add girth to the nose for a better fit just cover the bands and grooves, coat the noses then lube.  These are reusable and work well for me.  I've found it helpful to make a small  hole in the nose of the cap so pressure doesn't build with heat and push the bullet up in the cap.(silicone heals enough to not let powder in)  Part #58038 works for 30cal. and part #58039 works for 44=45cals.  Best to all    GP
