Running a Kimber 45 have been loading the 230 gr. TMJ with Bullseye at 4.9 gr. and OAL of 1.275.
Problem is I have the Lyman 48th edition and there is no data on the cast bullet.
Have a box of Lazer Cast 230gr. RN
With the cast bullet will I need to mess with the OAL?
If I can use the Bullseye will I need to mess with the powder levels to get the action to work right with the cast bullet?
Why with the different bullets weights does the OAL change?
Do I need to buy a new book for the load data?
Thanks Keig
