Awesome thread, Lee. You do a great job of explaining things. What are the sheets between the stock and the bags? Dryer sheets? Yep, they're dryer sheets. They help the gun track (aka slide) more smoothly on the cordura bags. -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Lee,
While you are this close to the subject, why don't you go ahead and explain why you use hard bags, and not some soft ones.

I just noticed from the picture on the last page. There's an inch between the bell end of the scope and the barrel. There is zero cheek rise on the stock. Is the intent that the ONLY part of your body to touch the gun is the pad of your finger? A pic of you in shooting mode would be helpful.

Charles – hard bags are preferable to soft. The problem with the latter is inconsistent tracking. If cushioned, the gun can do two things. First, it’ll come off axis upon firing. Any deviation from the centerline forces the shooter to realign the reticle when going back to the forend stop. A little adjustment is normal but we aim to minimize those movements (because they slow subsequent shots). In addition, soft bags don’t give enough lateral support and they can create drag. The gun must slide fluidly until it contacts your shoulder. I use Zircon sand in mine and have been pleased with the results. But there’s a trade-off. If the bags are packed too much and are overly hard, it’ll cause vertical. That’s because the bottom edge may vibrate or even hop under recoil. The exception to all this are shooters that squeeze the rear for POA shifts (as opposed to dial or joystick control). In those cases the leather has to be soft enough to accommodate the change. Later on I’ll do a more thorough review of rest styles, bags, and gun positioning. Gregg – short-range benchrest rifles never use a cheekpiece, even on rigs where you hold. They just get in the way and it’s another thing to bump. We also set the scopes higher than traditional rifles. This keeps our heads off the stock and promotes better flag reads. Plus it puts the objective farther away from that hot barrel (see the post on mirage). I’ll take video of me shooting free recoil when I’m out this Saturday. Quick update on my 67 gr flat-bases. They continue to perform and are quite easy to tune. I’ve flirted with a screamer, having seven groups under 0.150”. Here’s one from last weekend (27.7 grs LT-32, jam + 0.005”). The penny illustrates the small size of a BR-100 target:   -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Lee, I read the article and had to laugh a little since I use Butch's Bore Shine, Shooters choice grease, and own 4 Dewy rods. The truth is really there, that the improvements across the board, mostly came from Benchrest shooters. I have seen it more in Stocks and the Pillar bedding than anything else. Some target bullets, but Scopes seemed to have been a multiple reasons other than just Benchrest shooters. All the notoriety about Snipers and more Varmint hunters requesting better glass. I am really impressed with your bullets. Has anyone else tried them yet? What did your Dad think? Charles |

The rifle, load, & shooter all look like they're ready to enter a sanctioned match. Or.... have you done that?

Charles – I gave dad 300 of these 67’s and he likes the look and how they measure. He hasn’t shot any but did load some in his 6mm Wasp. I've also sent them to a few long-time competitors. They were told to give me the good, the bad, and the ugly on how they perform. So far it’s been all good. Surprisingly good in fact. One tried them in his rail gun and shot 0’s in testing. He then switched to his LV PPC and got 1’s. George Ulrich makes a helluva set of dies. Hines Precision makes one helluva jacket. So far the handle puller hasn’t let them down. Gunzo – I plan on competing at Mainville, PA in late July (IBS – Group). I’m also going to shoot the two score matches here in Virginia in July & August (IBS). -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Wind Flag Carrier _________________________________ Here’s a quick way to construct a wind flag carrier. The design came from Rick Graham who made the flags. First you’ll need an appropriately sized plastic container. Mine fit perfectly in a 66 quart bin. Then get a piece of 2 x 4 and drill holes slightly larger than your centers. 13/16” works well with the Grahams. Next take a router and cross slot the holes so they support (but don’t pinch) the shafts. Optionally, you may choose to urethane the wood like I did. Check the height to ensure the vanes don’t hit the bottom or lid, mark the sides, and screw the rack to the bin.      Total investment = $7 -Lee www.singleactions.com"Chasing perfection five shots at a time" |

After the Posts on this thread I actually expected to hear something of this sort. Seeing the results of your shooting was most impressive with the new Bullets. Give me a date here, of the Match in VA ( in August) That would be a good enough excuse to come that direction. I can't promise that I can make it, but we never know. Charles |

Video Taping Groups __________________________________ Squawberryman – you asked for video of free recoil shooting. Last Saturday I filmed a group to illustrate the technique. A few things to callout: 1) There’s about 1/2” of space between the stock and my shoulder 2) It may appear as if my face is lightly touching the stock. It isn’t 3) I rest my finger on the bottom inside edge of the guard. When I’m ready to fire I lift it a 1/4” and hit the trigger. 1.5 ounces later it goes bang 4) I left my shooting glasses in another range bag. Eye protection is a must. This video kicks off a project my good friend Boyd Allen recommended (he’s a long time BR shooter and one of the most knowledgeable guys I know on precision shooting). For two years he’s been telling me to film my sessions and capture the wind flags. I’ve finally taken up the practice and already see the value in it. By noting the bullet’s POI I can assess its movement against the flag position upon firing. This video only shows the first flag at 8:00 in the screen. Next time I’ll arrange it so all three are depicted. Here’s what you’re seeing in this six minute clip: 1) Shot #1 – this one is on the sighter. The barrel was already fouled from the previous group. This round simply put heat back in the barrel 2) Shot #2 – I dial the rest up to the recond. Now here I misjudged the flags. You’ll notice just as I touch the trigger the flag does a right to left switch. Sure enough, this corresponds to the left hole in the target shown below 3) Shots # 3 thru #6 – these are all on the record and make up the right half of the group 4) Temps were in the mid 90’s and the mirage was horrible. Normally I shoot faster in those still conditions but I’m trying to hit the correct POA. What you can’t see is the reticle dancing all about 5) The load was 28.6 of LT-32 with the bullet 0.005” ahead of jam. This is hotter than my go-to 27.7. In the high heat extraction was a tad sticky. This is evident when I pull the empties 6) It isn’t visible, but my right hand is constantly adjusting the windage and elevation knobs 7) The click you hear when loading is the extractor snapping over the rim. I need to lighten the spring to ease feeding (been meaning to do that for a year now) Here’s the target and it measures low 2’s. Had it not been for the one I let go to the left, I would’ve had a “1-something” group.   Some video of the type of wind we get at our range. We’re at the base of a mountain and the air tends to swirl around the tree line. This makes for very switchy wind reading. The view is from our new bench looking up toward our old shooting shed.  -Lee www.singleactions.com"Chasing perfection five shots at a time" |
