There should be approximately .050” protrusion. Protrusion isn’t as important as the amount of force exerted on the primer. Using an original 40 gram firing pin and the original 22-24 pound spring with at least .250” of travel are the most important factors. Greg Walley Kelbly's Inc.

Maybe there are problems with one or more lots of the Wolf primers, since there are so many complaints. With our action, as long as the spring is 22-24 lbs. and there is .250" of firing pin fall, ignition should be optimum. Interestingly enough, the only primer failures I've ever had were two...

No, a .062 firing pin would probably make matters worse. Are you using the original Kelbly firing pin assembly? What kind of trigger are you using? Greg Walley Kelbly's Inc.

Amen to this. I remember wearing out a really good rail-gun barrel dickering with issues like loaded round runout. It was all inconclusive and a waste of a competitive barrel. A lot of these ancillary issues are like spots on the sun. Greg Walley Kelbly's Inc.

Great idea Jack... If anybody has figured out when to turn that dial simply by looking at the way the group forms and the shape of the bullet holes, it’s you! I remember back when I was a lot more enthusiastic about these things…and we would meet at Kelbly’s in the DEAD OF WINTER trying to get...

Jerry, This is an interesting tidbit of information that you’ve posted here. I remember we had discussions about ten years ago on how to get fouling under control with a “magic solvent”, which unfortunately I have yet to discover. If I remember correctly, we both agreed that mechanical...

Tenon length and receiver face to the boltface is 1.340 factory spec. Check for modifications, wear, etc. for variations on the above dimension. Greg Walley Kelbly's Inc.

Welcome to Benchrest! I also recommend Mike Ratigan’s book. It is the best and most comprehensive text on modern-day benchrest competition. You should investigate the Blue Grass Sportsmen’s League website: http://www.bgslinc.com/...

2850 FPS with 140g Berger VLD. 25" Krieger barrel. N-150 powder and Federal primers. This is with a minimum dimensioned chamber and freebore diameter and length as specified by Hugh Henriksen for the above bullet. The firing pin assembly in the above rifle is a Remington specification...

100 ft/lbs minimum Thanks Jackie...Well said. We fix at least a dozen "bad rifles", "bad barrels", and "bad scopes" a year in our shop by simply tightening the barrel. Greg Walley Kelbly's Inc.

Zippy06 You’ve been given good advice here. Having thirty flags requires a substantial expenditure of money, even if you build your own. One of the reasons for having requested rotations at the FISS is to not only help disperse the costs and convenience of flag setting for the competitors...

HopeToBe, It is true that the 6PPC will shoot better aggregates overall when run at the upper end of the pressure window. In fact, every cartridge I’ve ever played with shoots better when loaded at close to the “listed maximum” pressures. I’ve never been sure exactly why this is true, but...

35mm Modifier Information 1. May cut incoming light by as much as 50% depending on brightness of conditions 2. Depth of focus increases by approximately 50% 3. Modifies view of mirage and target 4. It employs no lens. It is simply a perforated aluminum disk, weighing only 1/4 oz. I don't...

Jerry, Jeff and Jackie – good responses. Use a little common sense and good judgement/sportsmanship. Generally I check to see if my immediate neighbors have completed their groups before I start checking loads on the sighter, or verifying conditions with extra sighters after my record group...

Fantastic! Congratulations my friend! You’ve worked very hard to be in the top tier of the competitive benchrest community. I know how important it has been for you to achieve the high standards necessary to compete for winning aggretates at the National matches, HOF recognition and to...

There isn’t an optimum length necessarily. Most LV benchrest barrels are 21-22” in length. One could get away with a barrel as short as 18” (cut to 18-1/2” to leave a little extra length for recrowning). There will be some velocity loss with the shorter barrel, but it won’t be a significant...

Don't send out a Stolle action for anodizing - the steel inserts will corrode during the process. After bead-blasting we use CRC brand 3-36 corrosion inhibitor on the action after it is washed with Dawn detergent and water. This helps keep the fingerprint grime and dirt from accumulating. I...

Total length is 32.25 inches. The other dimension is action dependent and also depends on the person doing the bedding job. Greg Walley Kelbly's Inc.

and... Don't forget to thank the Weather Gods. :) We had absolutely perfect weather every day...very rare for the Super Shoot. It was good to see you all! Greg Walley Kelbly's Inc.
