[QUOTE="royinidaho, post: 792622, member: 2011"] You guys aren't thinkin' outside the box. Too much training, I guess.:) My 338 RUM die wasn't quite right for the chamber in the Rem. 700. Chamber is on the large side. So: 1. Use #7 drill bit and chuck in tail stock. Chuck desired case in head stock. Drill through the flash hole. 2. Using same set up but with 1/4 - 20 tap in tail stock tap the hole just made. Note turn the head stock by hand do not fasten down the tail stock. It's gotta slide.:rolleyes: 3. Scrounge around for a piece of 1/4 - 20 all thread or a long enough screw or machine screw or anything with a sufficiently long thread of 1/40-20 ilk. After cut to proper length Note: If done properly, or even close, the all thread/screw should be properly aligned so as not to have a bunch of wobble. This isn't all that critical as the honing process, at least the one I used was pretty much self aligning. :D It was a little hard on the wrist that held the drill motor though. :rolleyes: 4. Luckily there was some fine valve grinding compound around the place (saved a trip to town - a critical project criterion. Learned that tooth paste, while it did work was really slow. (Read impatience). Used Crest to finish.... Put what looks like enough grinding compound on the case, including the neck. 5. Carefully mount the die in the vice using a protective material to protect the threads plus allow for some wobble. There will be wobble!:) 6. Chuck the innovative honing device in the hand drill and go for it. Comment: one would think that brass would shrink before die enlarges. Not the case. The grinding compound embeds into the brass protecting it. It dries out fairly rapidly. Use oil or some such material, I used metal magic, to keep things from seizing. Comment: The dies are harder than Hades but too much material can be removed. Add compound as needed. Add/remove compound from neck and or case body to get desired results. Stop too soon rather than too late. By now you are laffing yur tails off but. . . The 338 RUM using a FL sizer die honed as stated above shoots sub 0.50 MOA @ 200 regularly with 300 Bergers @ 2735. And it did it the same day that I decided the die needed adjusting. Talk about impatience!!! Impatience is my strong suit. Machining and attention to detail is my weakness. :rolleyes: Sorry for taking up so much of your time . . . but what the hey! It was funny! This is like machinists porno . . . it'll stick in your mind forever....gun) [/QUOTE]
