I was going through all the SolidWorks files that I've done over the years and ran across the Lapua Fixture that I designed at the request of my friend, Adam Braverman, for the Lapua test facilities. As one can see by the pictures, the barreled action is bolted into the fixture, and the assembly is then clamped into the bench fixture at the test facilities for lot testing ammo.

As I looked at the work from the past, the thought occurred to me that some or maybe many of you would like to have a Lapua fixture of your own for whatever reason; cleaning, maintenance, taking your own fixture to the Lapua Test Facility; maybe all the above.

If you folks sound off to this post with interest in having your own fixture, I'll produce and make them available. The fixture is designed to accept left- and right-hand bolts and it doesn't matter which side the ejection port is on.

Edit to add: Based on some questions I received, I designed a Bushing Plate to take the place of my DBM for those not feeding from a magazine for lot testing and, to take the place of the DBM in order to bolt the receiver into the Lapua Fixture. I added the pictures below so everyone can visualize how this works. The Bushing Plate also provides lateral support so one doesn't crush the center of the fixture in whatever clamping system that's used.

The drawing would indicate "hints" that it will accept a magazine . Is that correct?
To be more specific, it accepts my DBM, which accepts a magazine, so one can feed from the magazine while lot testing. I'm designing a bushing plate right now to take the place of the DBM for those that wouldn't use a DBM. The bushing plate will also provide lateral support so one doesn't crush the fixture if it's clamped on the middle part instead of the solid forward part.

@RAVAGE88 Mike if the fixture will work with any 700 foot print(RimX 40X ECT)I'd like a couple of them.
The only thing that will determine if all Rem 700 footprints will fit is the dimensions/depth of the recoil lug pocket. I can oversize it in the model without issue.

With the shortage of Lapua, would it be a bad thing to do a full clean on my V360 and swap to Eley?

I know the Vudoo shooters say it’s spaced for Lapua and stick with Lapua/SK, but would it cause harm to try some Eley and swap back to Lapua if it doesn’t work out? Currently Center-X at 100 shoots the best for me, but stock is hard to find.

NO!
 
There's enough interest in the Lot Test Fixture (LTF)) that I'll move it into production, but I also received questions/feedback about the overall length.

A number of you would like to see a bit more material forward of the recoil lug pocket to provide more surface for the vise to hold onto. So, the overall length is now 15" instead of 12". A Bushing Plate will be included with the LTF; it's used in place of a DBM for the Gen 3 Single Shot and while doing maintenance and/or cleaning. Those wanting to feed from a magazine can add the DBM. I don't have pricing just yet.

Additionally, all parts have moved into production, as well as the Receiver Wrench for two lug and three lug receivers. I'll announce when I'm ready to accept orders.

Thanks to those that reached out with questions/feedback.

As Mike alluded to your issue is not with the magazine per se (depending on where you want to assign blame). The shaving is caused by the round not fully seating up into the bolt face. This condition is the result of the magazine spring not having enough force to overcome the tensioner and extractor. Is the tensioner and extractor springs too strong or is the magazine spring too weak? Pick your poison, but have you to fix one or the other. We have magazine spring tuning kits coming out for the Stinger mags very soon as we can control that on our end.
Any expected date when the tuning kits will come out?
 
Worth a reference look.

I run voodoo mags and shoot Eley.

I run poly Vudoo mags and have shot thousands of rounds of Eley. There is no feeding issue per se. The only issue that can come up is loading the mag. You need to be a little more careful as the Eley bullets can cause rim lock easier. After I load the mag I lay it back at a 45 degree angle and pull down the plunger and give it a little shake to settle the rounds in. Works great.

Other than that the only other issue some find is extracting unfired rounds. Never had that problem but heard it from some due to the bullet difference from Lapua.

But in the end shoot Eley if it’s all you can find.

When Paul sent out the later versions of the extractor & pusher after I started having problems with my early Gen 1 rifle, he also sent me a few spare plungers & springs for them, along with instructions on how much to shorten the plunger springs. Installing the newer parts - including the shortened plunger springs - fixed all the extraction/ejection problems I'd been having 100%. This was with V22 poly mags, and every one of them that I had have worked with perfect reliability ever since that time - which was late fall/early winter 2017.

I also bought a couple of Vudoo's aluminum 12 & 15rd mags, and they've worked well in my V22, Three-60, and early 40XB conversion rifles w/o any mods. Now if I could just get the L3i aluminum 15rd mags I bought not long after they came out to work as well as the Vudoo mags, I'd be pretty pleased...
 
I originally designed this DBM back in 2009 with a greater focus on centerfire applications. Based on the core group of end users I was building rifles for; I developed the Preload Piston to capture the back of Accuracy International AICS Magazines between two points. This eliminated rattle and provided a more tactile feel when inserting the magazine. The Preload Piston didn't work on the original Nylon VGW magazines, but it will work nicely on the new magazines I'm working on.

When the Rimfire thing started happening, the DBM was changed very little until I moved away from the Oberndorf style (inside the trigger guard) magazine release. This was during the influx of confusion (based on variation) about the proper length for the magazine release.

After introducing the TacMag Release, I received questions about why it was so thick. I didn't answer then, but I'm providing the answer now. I had this idea about how to do an adjustable release in a DBM, as they've become somewhat popular in a few chassis systems in an effort to make up for a broad amount of variation from one chassis and DBM to the next. However, I do like the idea of adjustability to fine tune feeding such a finicky round (of course, that being the 22LR).

I'll get these in production along with the Lot Testing Fixture.
