Of course, it is ALWAYS the neck length that suffers. If you measure your brass length after firing, you will find it is far short of chamber specs. This means you are jumping the bullet accross a void between the end of the chamber (neck) before it reaches the throat. This does nothing for accuracy and can build up carbon in this "unused" neck area! I only trim my cases .005" short of chamber length for this reason, and you can easily be .020" or more short when forming a Gibbs or A.I. Using the .270 0r .280 brass will eliminate this problem. Hope this makes sense. As far as powder charge, you can use the same charge in the Gibbs as the A.I. ........rich
Denny.....it just occurred to me that when you trim your formed 'o6 cases, you have to trim down to the shorter ones and there is always variation. When you form from a 270, you actually have some case length that HAS to be trimmed so you can end up with the exact same "correct" length for your chamber. Also, when you form the Gibbs case, you are using the same technique as I use for the Sherman, so why not chamber to a Sherman in your next one? I have the reamer and I even have a set of custom dies that I would consider selling.....Rich

Rich: You are quite right about the case length. When I read your earlier answer, I checked my reloading manuals for case dimensions, and by the time I got from my gun room upstairs to my computer downstairs I apparently had a senior moment and got them switched, thinking the 270 was shorter. My humblest apologies for questioning your expertise. I knew my cases shortened when formed, but never thought about using another case. I appreciate the suggestion. My cases always end up the right length because they stretch when fired, but as you pointed out, damage is being done to the chamber and throat of the rifle while I am waiting for the case to get long enough. I agree with you on trimming the minimum. I also am, after extensive experimentation, a firm believer on seating bullets very close to the lands. I bought a Weatherby Mark V without doing my homework, and I have never been as disappointed in a rifle in my life. The action and the clip are so short that you are condemned to seating bullets very deeply to allow them to feed, plus the Weatherby has a long throat, so the bullet basically goes on vacation before it gets to the lands. It makes a pretty good single shot, but I would sell it cheaply to anybody who wanted it. I read an article about the Mark V and it talked about very heavy bullets actually bending before they can get out of the case since they had to be seated so deeply. That sounds a little whacked out to me, but that is what it said, true or not. Thanks for all the info; you have helped me in a number of areas. I appreciate your offer on the reamer and dies. I need to research the Sherman and see if it is something I want to get into. I have so many .30 calibers, from a .308 all the way up to a couple of Lazzeroni Warbirds that I don't know if I want to build another one. But I appreciate the suggestion. Many thanks. Denny

Re: 25-06AI case forming

Thanks again.


I don't know if this is appropriate here, but I have been warning every site I go to watch out for a guy who sells guns and goes by the handle of Kiowadriver27. I bought a Sako M995 from him, and fortunately the gun was everything he said it was, but the deal was supposed to include a high end set of rings and two boxes of Lazzeroni ammo. He did not deliver on those even after multiple contacts. That was $400 worth of stuff. So if anyone who reads this is thinking about dealing with this guy, I would advise against it.

Sorry if I have broken forum protocol, I just don't want this guy to screw anyone else.
