Lee.... congratulations on spectacular shooting under “Trial by Wind.” Noticing, winner Martin and second place have the lowest X-count, with higher X-counts among also-rans.
Two factors are inescapable
1) NODE----the graphic of barrel harmonics, as registered at the muzzle. Vertical deviation not to be confused with velocity spread.
2) SHOT TIMING----wind condition pulls trigger.
These bench guns are the most accurate rifles in the world. As such, platforms for ballistic analysis. To include VERTICAL & DRIFT effect of rifling and wind. These minute adjustments are virtually meaningless without a rifle and bullet of extreme accuracy, lessons in EXTERIOR BALLISTICS, which the marksmanship incorporates. Those who think velocity alone defeats wind drift need to be stripped of their rangefinders, wind meters, and computers, to lay on the firing line stripped of props, to shoot the wind on experience alone.

Hi How are you? I want to make a Remington 700 Bolt and Action in my home for 223 rem. I searched in internet and find you. I am newcomer. I need all dimensions, CAD drawing, and any required matters. Can you help me or introduce someone to help me? with the best regards Mahan Back-Up Rifle _____________________________ I just added a .30 Stingray tube to my LV PPC. This creates a much needed back-up gun for IBS score competition. I’m not worried about the Martin action mechanically; it has been solid for 5,700 rounds. A barrel dying mid-season however is a concern. If one goes and I don’t have time to chamber and tune another before the next match, I’m cooked. This becomes plan B. Action – BAT DS Trigger – Bix N Andy Barrel – HV Lederer 18 twist, 4 groove, finished 23”. Chamber – .30 Stingray, 0.331” neck Stock – Dixie Rings – Harrells Scope – March 50X, fine cross hair reticle with 3/32 dot Tuner – Bukys TSI Weight – 11 lbs, 15 ozs     The gun is light for IBS score. Doyle Anglin got the stock to where it’ll make 10.5 pounds with a 20.5” LV barrel (6mm PPC). That’s good for group shooting, but is a lot of forfeited weight for 13.5 lb VFS. Even with the longer, heavier .30-cal and a tuner, I’m 1.5 lbs under. I may add mass to the fore-end depending on how it handles, Relief recesses were milled in the barrel channel to save weight. I’ve already devised a way to place removable lead blocks in those areas if needed. More expanded and neck-turned .30 Stingrays:  -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Match #53 Black Creek Winter League, Match #4 IBS VFS 100 yard ___________________________________________ It was a cold day for our 4th installment of the Black Creek Winter League. When we arrived at 7:30, the temperature was 17 degrees. By 10:00 it was still in the low 20’s. The wind wasn’t too bad but swirled just enough to keep you honest. I had a nice 3 X lead going into the 4th target. If I could stay clean and continue hitting 4 X’s on average, I stood a good chance of winning. But I came up short. On the 4th bull of the 4th target, I let the bullet fly under what appeared to be tame flags. Center held on the dot and the gun tracked beautifully. Then I looked through the scope and saw a hole in the 9-ring. I fired on #5 and took out the X. My friend had finished his target early and watched mine through his spotting scope. “The third flag at 75 yards made a hard left as you shot”, he said. Basically, I got caught in a shift and: 1) didn’t see it in time, and 2) even if I did, I was on the trigger as the flag turned. I ended-up 5th out of 14. That’s benchrest.

Match #54 Fairfax Rod & Gun Club Winter League, Match #4 IBS VFS 200 yard ________________________________________________ Saturday was another cold one with high wind. For the fourth time this Winter League, there were no 250’s. In fact, the best score at 200 yards this winter has been 248 out of 250. The conditions were ever changing, making it hard to reliably use sighters. Like others, I’d drop down to the lower right, fire a shot, and by the time I was back on the record bull, most of the flags had flipped. Compounding the problem was the wind hardly ever flowed in unison. Instead, one flag would be hard right, one would be hard left, and the others would be in and out. I managed to get out of there with 5th place. So twice in a week I finished 5th with the highest X count.  -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Match #55 Black Creek Winter League, Match #5 IBS VFS 100 yard ____________________________________________ We held the last match of our Black Creek Winter League on Saturday. The wind was mild, but the air was damp and cold. My good friend Chris Allen won his first match, while Wayne France and I shot 250-20x’s. He got me on the tie-breaker however.  The Winter League Champion was calculated on the best 3 out of 5 match results:  I enjoyed running the Winter League as Match Director and agreed to handle the series again next year.  -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Lee, I know the benchrest work has been going on for a few years now but it still seems like a pretty quick climb to that #1 spot for the overall winter league! Congratulations on a great season.

Looks like the Lee Martin answer to Would you rather be GOOD or lucky?
Nobody on the Firing Line wants to be unlucky. Yet, just how does one make it to the winner’s circle without skill?
Answer: not far.
To run a match AND compete means that the Nuts & Bolts of putting on the tournament steal time from the COMPOSITION of performance. While Bench Rest----and most other marksmanship discipline----is not a cardio-vascular pump, performance is built on DETERMINATION, and determination without composure is just a ricochet.
Take the well-meaning phrase, spoken as a competitor steps to the Firing Line: “Good luck.” Sounds like a curse. Better to say nothing, just nod. Or, “Good shooting,” or “Don’t forget to breathe.”
The frame around a picture does two things, it protects and separates the picture from its environment. For a competitor who doubles as match director, line officer, target setter, there is no frame to lock-out the ditch-digging. The transition from presenter to performer is immediate, without pause. Lee knows it all, from from chips flying off a milling machine to making his own bullets, loading ammunition, doping the wind.... to TIMING his SHOT. All the while making it possible for others to compete.
A tip of the hat,
David Bradshaw

Match #56 Fairfax Rod & Gun Club Winter League, Match #5 IBS VFS 200 yard __________________________________________________ Saturday was cold and we started with snow on the ground. But for the second week in a row, the wind was calm. In the prior four 200-yard Winter League matches, the best score was a 248. No 250’s had been shot. That changed last weekend with four and a stout X count by Chris Allen. His 14 X’s gave him back-to-back wins. I finished 3rd.   For the overall series, Tim Henninger took 1st, Wayne France was 2nd, Chris Allen had 3rd, and I got 4th place. -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Barrel Management _______________________________________ My first Stingray barrel has 3,319 rounds on it. It still shoots tight but like everything has a finite lifespan. It seems 5,000 to 6,000 is the norm for .30 BRs in competition. Some die sooner, others report strong performance up to 7,000 – 8,000. I average 2,500 per season and am not willing to gamble on Krieger #1. The Score Nationals are in late September and mid-October. By then the barrel will have amassed well over 5,000. Having it go to sleep on me in South Carolina or Georgia isn’t a risk I’m willing to take. So I installed a new Krieger 1:18 twist and added a Bukys tuner. The gun made weight at 13 lbs, 4.4 oz (heavy varmint limit = 13 lb, 8 oz). Krieger #1 has a lot of life left in it and can be re-installed in a pinch.  -Lee www.singleactions.com"Chasing perfection five shots at a time"

Barrel Tuning – Krieger #2 __________________________________ Like my other .30 Stingray barrels, 33.0 of LT-30 @ jam – 0.010” shoots the tightest. This is the lower node, moving at around 2,980 fps. The upper node at 3,030 is a close second. Once confirmed, I installed the tuner, backing it out a half turn. The first 3-shot group showed vertical (for reference, the inner circle is 1/2" in diameter. The second ring is 1". They look huge when photographed close-up):  I then moved the tuner out another 3/8” to the first mark (3/8” on circumference, not travel away from the shoulder). Three shots went into ~0.10” spread:  Getting aggressive, I moved another 3/8” to the next number. Those shots printed even tighter at ~0.05”:  Guessing I was about to come off the node, I moved another full number. Sure enough, the vertical reappeared:  I locked the tuner between the first and second marks; or halfway between the two positions that yielded groups 2 & 3 shown above. That’ll provide buffer in case the barrel wants to jump tune as conditions change.  -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Match #57 Black Creek Gun Club, Mechanicsville Virginia IBS VFS 100 yard ________________________________________________ The new barrel did well in competition, matching my best 100 yard score ever. Good friend Chris Allen and I shot in lock-step across the five record targets. The normal Creedmoor couldn’t decide it, forcing a double tie-breaker. Whoever dropped the first X gave up position. On target #1, I missed my X ahead of his first lost dot. He got the win and I took second.  This outing did a lot for my confidence in the new blank. The hardware is capable of winning, which puts the rest on me. And in benchrest that's where you want the onus to lie. -Lee www.singleactions.com"Chasing perfection five shots at a time" |
