[QUOTE="TeamCarnage, post: 2787160, member: 108612"] Ok, I have to add to the discussion because it seems we are all beating around the bush here. Accuracy is a function of combustion, harmonics and down range ballistics. If you change any of the three, accuracy will change in one direction or the other. If you use different brass with a different case capacity your velocity will change as a function of pressure change and neck tension change. Sometimes a small amount sometimes a large amount regardless of whether you are using the same charge of powder and primer. This will effect how long the bullet takes to exit the barrel. Which brings up harmonics. Your barrel vibrates at the shot, depending on where/when in the vibration the bullet exits the barrel determines whether the load/barrel is in tune with this sine curve of vibration. This is where seating depth and barrel tuners have an effect. The last is down range ballistics which is a function of velocity down range and bullet design and really not important for the discussion. Bottom line to the OP. You changed combustion of the cartridge so you need to do another ladder then do a seating depth test to get your accuracy back. [/QUOTE]
