Home Forums Reloading Big Game Rifles Seating depth trial

Did this test over 10 years ago using a proven load of 117 pro hunters for a base line. Seating depth test 110 Accubonds. Seating depth in the last group ended up being 10 thou farther out than the proof load of 53 grains RL22 and WLR seated 3.165. 110 load was 54 grains RL22 WLR and the last group was seated 3.175. The 10 thou was the difference between the base to ogive difference of the 2 bullets.
I always use a sharpie to mark the bottom of the case and leave the color legend at home. The 2 in 1 out seat deeper that Aussiegunwriter mentioned has been around for 20 years at least and does work.
As mentioned my hunting rifles have all ended up with a fair size jump, but target rifles have responded anywhere from a light jam to a small 5-10 thou jump.
