Attached is Creighton Audette's obituary published in the Dec. 1995 Precision Shooting Magazine. There were a lot of useful articles authored by Audette in PS as well as the American Rifleman. He exhaustively tested his theories concerning rifle accuracy. Note: in the attachment from Speedy...

Kev! I haven’t seen you in a while. I hope all is well. Keep in mind that carbide needs high speeds and feeds. Even with the sharp edge that’s typically ground on the chambering reamers commonly available (unlike a carbide porting tool used in industrial production), you’ll still have to...

Yes - Yes - and YES! I have fixed quite a few rifles that didn’t shoot by simply increasing the firing pin fall. Most of the rifles in question had fall around 0.210” or less total travel, and 22-23 pound springs. About ten years ago or so, I experimented quite a bit with ignition. I used...

Good explanation Mike. I think it is more important than what many shooters think to control the release point in relation to the tenon, so the whole length of the barrel is perpendicular to the face of the action. I also have evidence that is is very important to have the first few inches in...

Well said Jackie. -g-

Custom nuts! How many do you want? Why don't you find a local machine shop and give them a drawing and have them made from 4140 HT? Should be a pretty simple job for any shop that has a multi-axis lathe with live milling.

Another old great passed... Jim was one of my mentors when I started out in the game. He sponsored me when I joined as a member at Shelby Co. Deer Hunters, and was always enthusiastically helpful when I needed advice. He got me "in the click" when I wanted one of Warner Hail's much coveted...

Forget the anti-seize - use EP grease only. This issue has come up in these forums many times over the years. In my experience, the only suitable lubricant to use on barrel threads and bolt lugs are EP-2 rated greases…and even those seem to vary from brand to brand. Keep the anti seize for...

Proper sizing die dimensions The body of the sizing die should come very close to sizing the entire body of the case, although it isn't necessary to size "right up" to the extractor groove. If you find that you must have a case sized that far down the body, there is a chance that you don't...

They are tricky to adjust because there are six adjusting screws. You'll have to practice manipulating them to get a feel for how to move them properly. An adjustable torque wrench helps. They are of limited use, but are really handy for certain jobs. I used one with a homemade slitting saw...

Pete, there is a ER collet nut available that allows one to zero the runout in ER collets. I have used these for adjusting the runout out of reamers held in ER collets, and they are quite handy. Check the site: http://www.easyzeronut.com

Hornady Reloading Manual I have some sectioned cases I will take pictures of and post them when I get a chance. You can also check the older Hornady reloading manuals (1980-1990's vintage). In the instructions for how to reload for rimless cartridges, they give a nice illustration and...

Neat stuff Jackie. A manly job on a big manly machine.

Scribe a line Install barrel on action and put Dykem at the breech and muzzle. Use a square to scribe a line at TDC. Remove barrel and mount between centers in the lathe. Put a spring-loaded scribe in the tool post, align with the scribed line at the breech - move carriage to the muzzle and...

Is this a rhetorical question Butch? I don’t really know why the some of the chambers I inspected that were finished with the floating reamer holder exhibit these defects. Maybe the tooling wasn’t used properly?

Shortgrass...I agree with you. There is always something to be learned in the machining trade from those who have extensive experience. I have a few friends and acquaintances who run job shops, and are retired tool and die makers. They have taught me many things about the trade that I would...

Pusher or dead center I don't think I've ever seen a barrel reamed using floating reamer holder with the chamber on-spec. Usually they are oversized (>0.001") and elliptical. Often times, they cut larger in the back end of the chamber. They can also be oval or lobed. Ultimately the problem...

Mitsubishi "Micro-Dex" Get a Mitsubishi solid carbide SCLC type boring bar that takes the CGCT inserts: http://www.mitsubishicarbide.com/application/files/7214/4643/8970/b042g.pdf You can go down to a 0.200" hole 2" deep with these boring bars with a 0.0025" feed at 1300 RPM and a 0.015"...

I don't know if that is the case. You might have a point, although the final results on the target are about all we typically have to go by. I took flat base bullets and put a small (~0.001") score mark on the corner of the heel with a triangular file, and those bullets did not shoot very...

I won't be at the Shot Show this year - too much to do at the shop. I'll be at the SW Nationals for two weeks, so I'll be getting as much shop time in between now and then. I hope to see you at the FISS this year...WITH A RIFLE!
