Jerry, I guess we will just have to agree to disagree on that one. If the concentricity were that critical, then I should throw my barrels away after 100 rounds. The throat concentricity from the top of the lands to the bottom of the grooves of the barrel in this video measured about as close...

Respectfully disagree Here are results with my method at "the most critical area" referred to by some of the contributors to this thread. Again, it is a fallacy to state that good alignment and concentricity can’t be achieved with the steady rest used in the conventional manner… provided the...

? I'm not sure how one could have 0.010" at the throat, and no runout at the chamber if the centers were cut into the barrel bore properly. Maybe if a floating reamer holder were used it would end up that bad. I don't think I've ever seen one more than 0.001" FIM...even on the Ultra Mag and...

Actually Jerry, your reasons for using your method are the same reasons why I prefer using the steady rest. I can avoid cutting elliptical chambers and tenons that aren’t perpendicular with the receiver face by establishing a true center in relation to where the pilot registers during reaming...

Jerry, I don’t really have the time to put a video demonstration together, but if you can read my post #10 here for a simple explanation: http://benchrest.com/showthread.php?87931-kelbly-video-on-accurate-shooter&p=718373&highlight= I don’t normally like to interject or get into the fray on...

Wrong! No...using the steady-rest is not inferior: http://youtu.be/R7CZaBO8jNA

For what it is worth…A long time BR shooter and HOF member cooperated with me on a project by making a batch of 100 bullets; 36 were defective, and we mixed them with 64 proven excellent bullets made on the same dies and lot of jackets. The gross defects were as follows (six bullets each): 1...

Well said Charles +1 We always hear the bad news LOUD AND CLEAR. We seldom talk about the good news.

Excellent Sierra Jackets I've used 224 cal FB and BT bullets made on Sierra Jackets, and they were among the best bullets I've ever used. Recently, I've tried Bart's 6mm bullets made on Sierra jackets in the rail-gun, and they too were exceptional. Greg Walley Kelbly's Inc.

Yes indeed George...so I've been told :rolleyes: Are you coming to the Super Shoot next year?

After the barrel is cut to length, the barrel ends are faced off and new centers are put into both ends of the bore either with a 60° piloted center reamer or indicated and tooled in. This 60° center machining step is dependent on how concentric the bore is in relation to the section where the...

Actually, that particular photo is of a section of a benchrest grade barrel that was sawed off. The edge in the lower left is the band-saw cut edge. I was trying to focus the image on the rifling land/groove area. I have some other photos of the actual crown edge. I'll have to dig those up...

No. Boyd is correct.

I'm not really sure what you mean by "amount of trigger timing", but the most important parameters you need to concern yourself with is 0.250" to 0.280" total amount of firing pin travel with a 24 pound (original) spring using the original firing pin. Greg Walley Kelbly's Inc.

Get the appropriate contour barrel for the weight class Years ago, I asked a top BR barrel maker about fluting barrels for short-range BR competition. He said he didn't like the idea at all. When I asked him about fluting being the only option for a particular situation, he said "take off...

WOW! Conditions at Holton go to the extremes. It’s either blowing chaotically, or it lays down for record-setting conditions. Imagine shooting a teen agg and coming in 11th place! I hope the weather stays nice and everybody has a good time. I'm sorry I couldn't be there!

Process of elimination You may or may not gain accuracy by having the action trued. If you are trying to spend your money wisely - and are trying to get the best accuracy potential for your buck, you should do the following (in order): 1. Completely bed the action (no barrel block) 2...

Then Midland and Phoenix might as well be Saturn and Neptune.

Wind flags...with all else a distant second, third, fourth.... Flags definitely are the biggest help. Just look at the trophies awarded at the Nationals and Super Shoot where the aggregate sizes are listed. One can easily tell when wind flags were introduced. 0.1000" easily shaved off of...
