NF1E Posted November 18, 2023 Report Share Posted November 18, 2023 In the process of changing bullets for one of my precision rifles. Savage Model 12 FVSS in .223. I am working at setting the seating die to provide a finished cartridge that will allow the ogive on the Berger 55 gn fb target bullet to just kiss the lands. Painstaking measuring and setting up can help produce the best results. Step 1. Determine the exact BTO, Base to Ogive, for the particular rifle using a Hornady OAL guage and they exact type bullet that is being used. I like the curved gauge so it can be used on both semi auto and bolt rifles. Lock the length of the moveable bullet when it is touching the lands. Remove tool and bullet. Step 2. Measure the BTO of the cartridge while still in the gauge. Step 3. Measure the cartridge separately from the gauge and determine the exact BTO needed for this rifle. Step 4. Set up micrometer seating die to measurements acquired previously. Usually takes a few tries to get it correct, by trial and error method. Step 5. Load away and enjoy your time knowing you have done your best. Whatta Hobby! Quote Link to comment Share on other sites More sharing options...
NF1E Posted November 18, 2023 Author Report Share Posted November 18, 2023 I have no idea where the " bulle" in the topic line came from. It should not be there. Quote Link to comment Share on other sites More sharing options...
