[QUOTE="DMP25-06, post: 1676840, member: 27271"] Hello jbs2014 , Yes , I have tried the Satterlee method , but I have not tried changing the bullet seating depth to see if that has an effect on E.S. I have a flame-type annealing machine made by Mike's Reloading Bench , ( mikesreloadingbench.com ), that I use with Tempilaq to achieve proper temperature . I use an RCBS Chargemaster Combo to dispense the powder charge , and then I transfer that charge to my RCBS 10-10 Balance beam scale , to which I then trickle powder into pan until the beam perfectly zeros-out . If the trickler happens to drop 2 kernels of powder on it's final trickle , and the beam goes over zero , I will use a pair of tweezers to remove 1 kernel of powder , thereby balancing exactly at zero for the charge weight that I need . After I have filled all of my cartridge cases by this method , I will use an electric toothbrush touching the side of cartridge cases to vibrate and settle the powder inside the cases . Final inspection is to use a flashlight to visually inspect all cases to verify that they are equally charged before seating the bullets . After seating the bullets , I check the runout to verify straightness . The cartridges that I load and shoot most often are : 6.5CM - Peterson Brass , CCI BR-2 primers , H4350 and RL26 powders , 147 gr. Hornady ELD-M bullets . .308 Win. - Federal GM brass , Winchester LR primers , Hodgdon Varget and IMR 4064 powders , Sierra Match King 175 gr. bullets . .300 Win. Mag. - WW brass , Winchester LR Magnum primers , Hodgdon H1000 and Retumbo powders , Berger 215 gr. Hybrid and Hornady 208 gr. ELD-M bullets . And new toy , 7mm-.300Win.Mag. , that I am currently working on load development . SIG .300WM brass , necked down to 7mm in 3 steps with neck bushings , Federal 215 Gold Medal match primers , Hodgdon H1000 powder , Berger 180 gr. Hybrid and Hornady 180 gr. ELD-M bullets . Thank you for your interest , DMP25-06 [/QUOTE]
