[QUOTE="Alibiiv, post: 1975888, member: 69192"] After the rifle was built, .270 Ackley Improved, I sent three, full-power fired pieces of brass from the rifle to Hornady, they in turn made a custom set of dies for my rifle. I also had a hydro-form die made when the custom dies were being made at Hornady, these did not work out and I wouldn't purchase them again from this company. I only hydro-formed 10 cases when the die stopped functioning, the piece that is hit with a hammer, the plunger, to form the brass would not slide into the die itself. I contacted Hornady, [I][U]after a week[/U][/I] someone called me back, I told them the problem, and another plunger-spindle was sent to me, that plunger-spindle did not work either. So.....I have a lot of money invested in a piece of equipment that does not work, I have to use a pair of pliers and a hammer to get the plunger spindle to pull out of the die. I am not happy about banging Hornady's hydro-forming dies, however they have earned it, would never buy a hydro-form die from them again!! I use the cream-of-wheat process, this seems to work quite well, however have found that it is necessary full-load fire-form after hydro-forming to get a true representation of the chamber. If I use a fully loaded parent case, .270 Winchester, the case will be an exact duplicate of my chamber, this process has never failed me; however, a full load .270 Winchester is another round down the barrel of this rifle. Depending on the reamer and the gunsmith, with the parent cartridge you may find the bolt to close hard on the parent casing. I have two rifles,, in .270AI, that were built by the same gunsmith, at the same time, using all the same components, using the same reamer. When I close the bolt on a parent-cartridge in my rifle the bolt closes extremely hard, yet on my son's .270AI his closes as it ought to.
