if you're using Bullseye...... be very, very careful that you do not double or triple charge your cases...........you can reach the maximum load of Bullseye with very high pressures, using just the slightest amount of Bullseye.........you can easily double charge your cases & with some calibres, even triple charge a case & not have the powder overflow the cases.......we only loaded Bullseye when using a single stage press, & charged the cases with our old RCBS powder thrower.....then using the Mark 1 eyeball to insure every case in the RCBS plastic loading block had the same amount of powder in it.....I'd be too afraid to use Bullseye powder when we're using our Dillon 550 to reload.
be safe, enjoy life, journey well
