DI Precision (about post)

David Lott · Feb 15, 2025

I wanted to take a minute to explain what we are about and what our focus and goals are. I am not a gunsmith or a machinist. I AM a shooter(former hot rodder) and everything I do and think is always from behind the rifle. When I started shooting PRS rimfire in 2017 I had no idea what I was doing other than I like to shoot and being competitive I thought this could be fun, my first rifle was a CZ455 and was somewhat disappointed so I ordered a custom 455 and again was disappointed in the accuracy (side note I learned how to reload for precision from David Tubb over text and I got spoiled on what true precision and accuracy were.) When Vudoo came out my first thought was they are crazy, no one will spend that kind of money on a rimfire, shortly after a guy shows up with a Vudoo and promply wears us out with it, so on the way home I reached out to Vudoo to order a barreled action, after talking a bit I asked if they would make me a deal on 2 and Cole countered with buy 3 and I will set you up as a dealer, DEAL I said and that is how all this started. After I supplied pretty much all the shooters at TX precision matches in Navasota we all quickly found the start of feeding issues that Vudoo got famous for. Now looking back we KNOW it was not the rifle but the way we were using them, We added weight and made magazine blockers long before anything was commercially available. One day after the match as we were discussing our problems I thought what if we had a longer heavier barrel, so a text was made to Paul from Mullerworks and he sent down a 1.250 16 twist blank, balance problems solved and we did not lose the accuracy we were getting from the shorter barrels. Fast forward to I think I can make a business out of this. Now the question was never can we chamber and build an accurate rifle but could we do it consistently over and over in a semi-production format? That sent me CNC shopping and after many calls around the country talking with various shops I ended up with a Doosan 2100 LSYB turning center(remember I am not a machinist so I was as lost as can be but I knew that I did not want to handle the barrel twice to tenon/chamber and then cut the slots on a mill, so a steep learning curve ensued). I made a custom jig to hold the barrel in the hydraulic jaws and off to races we went. Below are a few samples of results we have gotten the last couple of years sending in a few at a time to see where we stood. I also included a few from some customers sending theirs in. The point being I want yall to understand that this is a lifestyle choice I made to build and provide the best product that I can make and feel good about selling it. We test each rifle for accuracy at 50 and 200 yards, If I am not happy it doesn't ship until I am confident that it will perform to the customer's expectations.

I never received a test target with mine last October

Are you talking about the above test center results? if we agreed to send that one in, what was your name so I can send it to you?

fiddlefadel · Monday at 2:30 PM

Whe I spoke with you about ordering you said that you tested the rifle at the Lapua test center. I did not get a printed target however my rifle had been shot a lot when I inspected the bore it looked like it had about 200 rounds through it enough that I cleaned it. This was last October.

I've heard great things about David's rifles. Sadly I have way too many rifles right now. I put up a cert for some good work for David on the PX if anyone is looking for some DI work.

David, do you specialize only in PRS style builds? I am currently shooting ARA Unlimited with my Vudoo 360 repeater and doing well but thinking about going to a single shot, right bolt, left port in a Vudoo or 2500X

tlsmith22 · Wednesday at 6:03 PM

Idk if David spun my DI Vudoo barrel or not but I have never seen a 22 shoot as good as this one.

I do more NRL/PRS style than anything but I have built a hand full of Bench rest on Vudoo single shots and 2500X,

If in the last 3 months I am doing all of them as my long time machinist got a job closer to home,

wraithdu · Wednesday at 8:24 PM

I myself have one of those made by the man himself, built in Nov/Dec. I've had great results so far with my own lot testing in Lapua Long Range. I'm heading to the test center in OH next week, so we'll see what some of the slower stuff does.

I’ve only tuned at an indoor 50 yard range, however, these were my results yesterday with a recent 360 you did. I’ll check the tune at 100 when I get to a range with some distance. The top row was only foulers. This was with Eley Match. The rifle loves it!

Sir, Have you figured out how to keep up with which end of the barrel the bullet comes out of ?!?!?!?!? LOL!!!

Why yes I have lol had to re slug a few before I thought why don't I just write what end is what BEFORE I cut the ends.

I have sent my V22S with an ACE barrel to DI to have a new 26” MullerWorks barrel with a Ross taper installed. The V22S with the ACE barrel did not meet my expectations, and in fact, my V22 3-60 with a Bartlein barrel performed better. I am looking forward to getting it back, and I am confident that David will work his magic on my V22S.

That is my fear! I have a single shot BR specific rifle built and it won't out shoot my current 360 with 26" Shilen ratchet
