These are component bullets used to reload cartridges for modern or vintage rifles chambered for the .38-55 caliber cartridge; this is not loaded ammunition. These are newly manufactured, hand-made, semi-jacketed, soft point bullets with a 0.200" meplat (flat nose) that are perfect for tubular magazines of all lever action rifles. I try to stock 0.377" diameter bullets for a quick turn around for my customer as this diameter is the most popular for this caliber. If you don't know your firearm's groove diameter you should consider getting my .38-55 caliber slugging kit. I try my best to keep these in stock but some finish time is still required as I must install cannelures as requested and package as requested as well but I should be able to ship within a week of ordering. These are excellent bullets that will keep any .38-55 shooting like it should.
