I started reloading last month, beginning with the 38spl round. I've reloaded 300rnds of .38spl +P with speer's 125gr JSP with no issues. Everyone went BANG, good accuracy, still got my fingers and eyes.
To save some money I decided to reload Speer's 158gr LRN bullets instead. (#4647) Then I hit confusionland!
The speer manual number 13 says to load these rounds to an OAL of 1.510, which means seating the bullet far past the crimping cannelure. By comparison I seated the JSP rounds right to the cannelure, which matched recommended OAL.
Here are the numbers:
38spl case: 1.1550
#4647: ~.675
Cannelure starts at: ~.460
Even if I seat to the very edge of the cannelure I'm at 1.6150, which exceeds the max 38spl case length by a fair margin. Should I ignore the cannelure? If so, why the heck is it there?
I'm sure there is a good and obvious answer to this question! Perhaps I have ingested some illicit narcotics?
