[QUOTE="25WSM, post: 1917091, member: 38048"] From what I'm told by the guys that have been doing this for way more time than me is small brass give a slightly slower ramp up of pressure. A neck sized case doesn't need to expand any and the pressure ramps up faster. They say that's why some fireforming loads are more accurate than once they are sized. They claim the bullet gets a softer start. I don't have any scientific data to prove or disprove this. Just what I've been told by guys doing this for 50 yrs. Maybe PO Ackley wrote about it somewhere. They also say brand new brass shoots better because it's small. The turd in the violin case. Shep [/QUOTE]
