If you use mass-production ring sets, other than Burris Signature Rings or SAKO Optilock Rings (which both feature polymer inserts), you can benefit from lapping your scope rings. Lapping your rings, when done properly, with the right tools, can improve the fit of the rings, reducing bending forces and stress on the scope. Properly-lapped rings are also less likely to leave prominent marks on your scope tubes.
Forum member Boyd Allen is a strong advocate of ring lapping for factory-produced ring sets. He’s tried various lapping tools and he believes that the Kokopelli system is one of the best available. Custom crafted in Kalispell, Montana by John Werre, the Kokopelli lapping system combines a specially-machined lapping rod with patented flat-ended scope alignment bars.
Kokopelli Lapping Tool
John Werre, Kokopelli’s owner, explains why his lapping tool works better than most others: “No one was making a lapping bar that would lap anything more than the bottom half of the rings and they were made of rolled stock and only a very short stroke was possible, rapidly wearing out the bar due to the limited area of use. I did something entirely different. I designed the bar to be used with the top halves of the rings in place and utilizing a long stroke thereby distributing the wear over the entire 12″ length of the bar. Why just do half a job?”
John adds: “Another problem was that the lapping compound would readily scrape off the bar, slide around and wear the bar out as fast as the rings. I added the spiral groove to stop the scraping off of the compound and later changed to a much softer steel and put a very rough, but carefully designed, finish to accept the lapping compound, actually allowing the grit to be driven into the surface of the bar. The nasty, scruffy rough finish is full of grooves and valleys of a depth designed to ‘catch’ the very sharp lapping compound, imbedding it into the bar. You then will wear out what you’re trying to lap rather than wear out the bar at the same time. The spiral grooves also cannot catch on the edge of the scope rings as can one which has annular grooves cut perpendicular to the axis of the bar in separate rings. I have very good reasons for every unique feature of my tools. Every aspect has a valid design behind it.”
Kokopelli Scope Alignment Bars
Kokopelli’s patented scope alignment bars have flat ends and work differently than alignment bars which use pointed tips. Kokopelli came up with a flat-ended design because alignment bars with pointed tips can yield a “false positive”, meaning the points can touch when the scope rings are out of alignment. To demonstrate, try this simple experiment. Take two ordinary pencils. With one pencil in each hand, hold them parallel with the pointed (lead) tips touching. Now simply move the outboard end of each pencil, while keeping the tips touching. You can see instantly that the tips can touch even if the pencils are way out of alignment. The same thing can be true of scope alignment bars.
With the Kokopelli scope alignment bars, each bar is an exact cylindrical projection of the interior of each ring. When you bring the bars together, if they don’t mate perfectly, i.e. if there is any gap between the flat ends when the bars are touching, then you know you have an alignment problem. Kokopelli claims that misalignments as small as .002″ can be detected. John Werre explains: “The bars actually are a three-dimensional projection of each ring ‘hole’. You’re looking at a solid representation of the hole through the ring. Put one bar in each ring and you can then compare the axial alignment of the ‘ring holes’ to each other. If the ends match and are flat together you have reconstructed the bars into one [cylinder] and the alignment is PERFECT.” Below, in Figure 1, you can see rings that are out of alignment. In Figure 2 you can see rings that are properly aligned. Interestingly, the misalignment illustrated in Figure 1 did NOT show up with pointed ring alignment bars. This amount of misalignment can create up to 3/16″ of scope tube bending (depending on ring spacing).
The function of the Kokopelli lapping tool and alignment bars are described in greater detail on the Kokopelli website. The lapping tool and alignment bars are sold separately, or as part of Kokopelli’s complete Accurizing Kit shown below. The kit, which combines Scope Alignment Bars, Lapping Bar, pointer rod, and lapping compound in a fitted box, costs $84.50 for 1″ rings, or $91.00 for 30mm rings. For more info, contact John Werre at Kokopelli Products, 3820 Foothill Rd., Kalispell, MT 59901; phone (406) 755-3220. NOTE: Kokopelli has maintained the same prices since 2003. However, due to increased costs of materials, John Werre plans to raise his prices by mid-January, 2010. You can get current pricing by ordering soon.

Louisiana Precision Rifles (LPR) has a new custom action with all the features you could want in a deluxe Rem-700-clone receiver. The new Rem-700 footprint LPR action is available in stainless steel or chrome moly, in Right Hand, Left Hand, Long- or Short-action versions, suitable for .223 Rem through .338 Lapua Magnum.
LPR’s owner William Roscoe included some very nice features in this new action — it’s a far cry from another “bare bones” Rem-700 clone. The bottom of the action features a .125″ radius cut for modified detachable box magazines, and the receiver is otherwise compliant with both ADL and BDL bottom metal. Notably, the new LPR action is slightly longer than a standard Rem 700 receiver. The LPR action has a longer 1.0625 x 16 TPI tenon for better barrel support.
In the front of the action is a precision-ground, double-pinned .312″ recoil lug. On top of the action, Louisana Precision includes a custom +20 MOA scope rail, that is both double-pinned and secured with oversize 8×40 screws. Roscoe has relocated the bolt release to the side where it is raised up out of the stock line so you don’t have to make a large cut-out in your stock.
The bolt is an inpressive piece of work also. It employs a fluted, one-piece bolt body with a threaded handle to accept custom bolt handle knobs. At the rear of the bolt, the cam angles have been carefully modified for smoother extraction and better camming. The front of the bolt is fairly unique. The ejector has been repositioned, and the bolt is fitted with an ultra-reliable mini M16-style extractor. The new LPR action design also allows a 100% captive firing pin tip.
Available on Complete Rifle Builds Initially
This receiver is available right now on complete rifles built by Louisiana Precision Rifles. Individual receivers will be offered for sale at a later date. The cost of a complete custom rifle built by Wm. Roscoe of Louisiana Precision ranges from $2,950 to $3,500 depending on finish, added options and stock choices. Estimated lead time is roughly 30-45 days on receivers. For more info, visit LouisianaPrecisionRifles.com, or call William Roscoe at (318) 422-0421.

In our Shooters’ Forum, member David C. posted this account about David’s recent positive experience with John Pierce of Pierce Engineering. It’s nice when a good deed gets acknowledged. Dave wrote:
“I don’t know if you guys know or have heard of John Pierce, but he makes a fine action and custom rifles if you want one. Well his shop is only about 5 miles from me so I went to see him yesterday. I had bought a Stevens .243 with the idea of making a 6mmBR out of it. I had it apart and had cut 0.600″ off and put the same amount of threads on it. I just wanted [John] to ream it for me if he had the time.
Well, John took one look down the barrel with his borescope and said ‘It’s Junk’. He then went through his take-off barrels and found a nice stainless bull barrel and said ‘this will work’. He then crowned it, cut it off and threaded it with a shoulder so no Savage nut was required. He then reamed it and put it all back together and checked the head space.
If that wasn’t enough, John then loaded 15 cases for me, gave me 100 primers and showed me around his shop. Now mind you I had been there most of the morning. Let me tell you, this guy has his stuff together. Boy does he make a great action. I said, ‘Well how much do I owe you?’, and he said ‘Nothing… just go shoot it and have some fun’.
I did buy him lunch, LOL. Guess where I will be getting my next rifle? Thanks John, you sure made this old man’s day.” – Dave C.

Lee reloading products have always represented good “bang for the buck”. The Lee Classic Cast “O”-style press is no exception — it works as well as some other presses costing twice as much. One well-known “boutique” bullet maker has recently switched to Lee presses because the tolerances and lack of slop were actually superior to more expensive presses.
The Lee Classic Cast press is a well-designed unit with a strong, cast-iron frame and all-steel linkage. It has important (and very cool) features you won’t find on an RCBS RockChucker. First, the ram is drilled in the center and fitted with a plastic drop tube so spent primers drop right out the bottom (where you position your trash can). Second, the handle adjusts for length and “attack angle”. This allows you to change the leverage to suit your task. As Lee explains: “The start and stop position is adjustable with a 48-tooth, ratchet-type handle clamp. In addition, the handle length is completely adjustable. Shorten when you’re loading handgun and short rifle cases.” As you can see, you can also mount the handle on either side, left or right.
 
You can purchase the Lee Classic Cast Press for under $86.00 at major vendors. FactorySales.com offers the Lee Classic Cast for $73.40, item 90998. MidwayUSA sells the Lee Classic (item 317831) for $85.99. Natchez Shooters Supply also offers the Lee Classic for $80.99, item LEE90998.
 Mark Trope of SurplusRifle.com has written a detailed Review of the Lee Classic Press. He notes that the press is “southpaw friendly” and he praises the priming system. Mark found that the spent primer drop tube worked very well and that the press “works perfect and has great sensitivity” when seating primers.
Not yet convinced? CLICK HERE to read comments from actual Lee Classic owners. Here are some highlights:
“It has a large, heavy-duty 1-1/8″ diameter ram that has been drilled out for spent primers … and a long clear plastic hose attached to it so you can route it to a trash can. [This is] a VERY well thought-out way to collect ALL primers to your trash can when you’re decapping.” –D. Oldham
“Fit and finish are impeccable. The spent primer disposal system is simple and neat. There is no spring or flexing of any kind. There is virtually no play in the ram, which is a good tight fit in the frame. Operation is totally smooth.” –R. Smith
“Totally outclasses any other press in its price range. Runs with presses in the $100-$120 range.”–W. Rose
“I like…the position of the ram at priming. The Lee seats the primer with the ram at the bottom of the stroke vs. the RC II, which seats in the middle of the stroke. Priming at the bottom of the stroke gives you a much better ‘feel’.” –M. Gallagher
