Wait.... I recognize that brake! You picked up a 50 a while back as I recall! Now that is the ultimate bullet to swage! Your going to have to lengthen your range for that one  BT Yep, the brake is attached to my State Arms .50 BMG.  Also, George Ulrich called. My .30-caliber dies are done and he’s finishing the presses. Everything should arrive next week. -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Light Varmint 6 PPC Build – Part II _____________________________________________________ I recently chambered a 13.75 twist Lederer LV barrel. Initial centering was done on Deltronic pins inserted in each end. The pins are precision ground to 0.0001” for exact fit. In the below video, you’ll see dead zero at the breech and only 0.001” at the muzzle. That’s damn good over 27”, especially since the last 5” gets chopped: A dial indicator, accurate to tenths, was then run across all four grooves. Each zeroed without further adjusting the chuck. That proves perfect concentricity between lands and grooves.  BAT actions have cone bolts. That 25 degree angle must be approximated in the tenon and cut deep enough for gap. I set mine at 0.005”.  The threaded, coned, and chambered blank in 6 PPC - don’t mind the dirty threads. I used anti-seize to prevent galling when test fitting it to the main ring.  A Bix N Andy trigger was timed to the action as well. BAT ships two trigger hangers with their receivers. The first is a 0-30, the second is a 10-20. By rotating the hanger 180 degrees, you can time cocking piece and trigger sear engagement on close. The goal is to prevent additional cock-on-close, which can disrupt the gun. “0” puts the trigger sear the farthest forward, 10 puts it 0.010” back, and so forth up to 0.030” rearward. My Bix and BAT DS needed the 0 position for effortless bolt drop. Pull was set to 1.5 ounces.   -Lee www.singleactions.com"Chasing perfection five shots at a time" |

30-Caliber Cores ____________________________________________________ Inserts I just machined for my core cutter:  Thirty calibers are made from 0.250” wire, so I reamed the holes ~0.260”. Like my 6mm bullets, I’m using Crown Metal BW comprised of 99.25% lead and 0.75% antimony. Cut weights are computed as follows: Desired bullet weight = 114 grs Hines 0.925” jackets = 39.84 grs Final core weight = 114.0 – 39.84 = 74.16 grs I want to bleed 2.5 grs during swaging. That puts cut weight around 76.70 grs My first batch of 1,000 rough cores:  -Lee www.singleactions.com"Chasing perfection five shots at a time" |

About how long dos it take to cut the 1,000 cores?

About how long dos it take to cut the 1,000 cores? About 1.5 hours. That entails cutting the wire to 30" lengths, wiping them with acetone, and shearing the cores. Beyond that, they get lubed and swaged to final weight. That adds another 2.5 hours or so. -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Spoke with Lee tonight and am elated to report he spent an excellent day behind his benchrest rifle. This score shooting, where a target the size of a fly approximates shooting handgun silhouette with a target rifle. The benchrest target equals a dot of a sharpened pencil.... Lee far & away nailed most of ‘em. We talked shop for quite a while.Lee’s next appointment is this coming weekend, bench work @ 200 and 300 yards. Without a prior opportunity to dope his rifle @ 300 yards, Lee must go in cold. Even with velocity of 3,000 fps, a spitzer cannot escape the bite of wind. In handgun silhouette, I used the pig @ 100 meters to map wind drift. For Lee next week, I believe bullet holes @ 200 yards draft the roadmap to 300.
All of the mechanical perfection built between buttplate and muzzle and blessed by a bullet must pass through the shooter to ring true on target.
Our best shot comes as we ride our bullet. To immediately act on intuition introduces the alchemy of sharpshooting. My hat is off to Lee for this week’s performance. May it pave the way.

Match #25 – Mechanicsville, VA 100 Yard VFS ___________________________________________ I came close to winning the match, but more on that later. The day began with a pretty stout storm. Heavy wind actually blew rain up under the line’s roofing. Most guys had to cover their guns prior to shooting, myself included:  The rain subsided by the first record target but the wind remained stiff. On the warm-up session, I fouled my barrel with 3-shots on the sighter. They went in one hole - a good sign. For that target, plus the first two records, I hit every X. I knew the rifle was on but purposely didn’t look at the standings. In those conditions, I was just trying to stay clean on the 10-ring. Never figured I'd be in the running for 1st.  Shooting off the bench to my left was Wayne France. Wayne is a phenomenal shooter and has given me a lot of sound advice. Once we finished, he looked over and said, “I think you may have won this. We were tied going into target #5 and it appears we both just shot a 50-5X. If so, you have me on the tie-breaker (ie, Creedmoor rule)”. As it turns out, I missed one X by a few hundredths (for reference, the dot is 0.0625". Much smaller than it appears):  Wayne took 1st place with a 250-22X. I came in second at 250-21X. The 300 yard match David eluded to above is May 20th in Thurmont, MD. I’ve never competed at that distance. Expect it’ll be an eye opener if there’s big wind at play. This weekend, I’m shooting 100 yard VFS at Fairfax, then 200 yard VFS Sunday in Bridgeville, Delaware. The following weekend are the IBS Pennsylvania State Championships in Dallastown, PA (100 & 200 yard in the same day). -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Congrats Lee. I haven't shot that game much, but enough to know the feeling of a strong finish.

Match #26 – FR&GC IBS 100 Yard VFS ______________________________________ Saturday was hot but the mirage played nice. My .30 Stingray shot well, netting me 6th place. I stayed clean and got another “250 Club” decal. 15 X’s was decent, however a little more aggressive hold could’ve nabbed a few more and a higher finish.   -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Match #27 – Bridgeville, Delaware IBS 200 Yard VFS _________________________________________ What a difference a day makes. Sunday was cold and we worked on the front edge of a massive storm. Winds were steady at 15 – 20 mph with gusts over 40. It just never let up. Couple that with the eastern shore’s sand base, and at times visibility was poor. I shot video to illustrate the brutal conditions. The first half depicts about as good as it got on wind. The second half is the weather showing its teeth. At 200 yards, I was holding off 3 – 4 inches. We were indeed steering bullets into the 10 ring. For the second day in a row, I finished in 6th place. All things considered, I’ll claim that as a small victory.   Looking back at the benches. Note all the sand....very tough to navigate through in high wind.   The wailing wall.  My friend Chris Allen and I shared a bench.  Wayne France left, Chris Allen right. Wayne won the event.  -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Some tough shooting conditions really start separating folks. Glad to see that you did well and brings me to this question.
Did you, or do you, have some info mapped out? for wind changes? Or did you just have to calculate quickly from a sighter, and then go from there?
I just know that I have shot in 40MPH winds with my 22-250 on purpose for learning and did so at 300yds. Ballistic calculator helped me.

Did you, or do you, have some info mapped out? for wind changes? Or did you just have to calculate quickly from a sighter, and then go from there? Charles - there's no way to model holding off. The flags change so quickly, shooting sighters is the only way to go. Complicating this is the fact you're forced to manage multiple reads. Last Sunday, turbulence caused the flags to tail in many directions and intensities. You just have to be fast in getting from the record bull to the sighter and then back to the record. Controlled speed is paramount. -Lee www.singleactions.com"Chasing perfection five shots at a time" |
