My new DI Precision B14r

[bostonbullit]

Got my B14r action back from DI Precision with a nice new 25" Muller 1:13 twist 1.125" straight taper barrel fitted up! I've been to the range the past couple of weekends getting things tested and dialed and it's already shown that it shoots better than I do. I've tested it with Wolf, Eley Club, RWS Rifle Match, SK Standard Plus (3 lots), SK Long Range Match (2 Lots, labeled Rifle Match on the target photo), Lapua Center-X (2 lots), Midas+, Super Long Range, and X-ACT.

It didn't like the cheap Wolf at all, and wasn't excited about the Eley Team. Those are both cheap Eley ammos that I don't really use so that's ok with me. The Standard Plus which makes 1030 out of my factory B14r and B14r Heavy barrels struggled to get to 1000fps out of the Muller and didn't group well so I'll save that stuff for the other rifles. Things started pulling together with SK Long Range Match and got better from there. Unfortunately the very expensive X-ACT absolutely hammered at 50yrds . Multiple ammos put up 5 shot groups in the 3s regularly and almost everything stayed under half-MOA at 50. It was HOT that day and I flubbed a few shots but I do that at matches so I guess this test is representative of what I can expect on the clock. The 50yrd target has data next to some of the targets, it's AVG FPS, Extreme Spread, and St Dev of all 10 shots of that ammo.

When the target moved to 100yrds things opened up but I had a lot of respectable targets (for me anyway). The winner here was the Midas+ which put up 5 shot groups of .448 and .435. Hot damn I wish I had a case of this lot number! The more wallet friendly SK Long Range Match was in the 7s and 8s as was the mid-price unicorn Center-X. Just about everything stayed sub-MOA at 100. The target is a big hard to read because with so many diff ammos I had a few random wandering shots.

Most importantly I have 350ish rounds down the pipe and not a single malfunction! Can't wait to get this rig out to a PRS match and see how it performs

Very nice build…congrats. I plan on having DI build a BR rifle for me, as my back surgeries are preventing me from shooting in the NRL22 world. Have you thought about sending the rifle to the Lapua or Eley ammo-camp? I just had a rifle come back after waiting about 7 months for my reservation to come up. I sent my rifle to the Arizona location; such a great team out there. They tested 16 lots of Midas+ and Exact in the rifle. Surprisingly, the Midas+ shot far better than the Exact in my rifle…lucky me, the price was far more attractive. Unfortunately, they only let you buy a single case of ammo when the process was completed. Good luck in the match. Warm regards from NH

Working with David at DI was great, he spent some time on the phone going over what I was going to use the rifle for and made recommendations on the best setup based on guns he’s built. Total time at his shop was in-line with his original estimate and as I said the gun is performing to expectations.

I would love to send the gun into one of the Lapua test centers, and probably will if things ever quiet down. The things that might prevent it are the shipping; the site says they only accept shipments from an FFL which is a PITA, the year wait, and the limit of 1 case. If I knew they would have a few lots of Center-X, Super Long Range, and Midas+ and I could get 2 or 3 cases of whatever tested best then I’d do it in a heartbeat. I’d rather eat the cost up front to know I have ammo the gun likes for a couple of PRS seasons

That's an issue...long wait times and then limits on it's preferred lot. Me personally I'd keep the chamber clean and season the barrel some more, get closer to 1,000 rds down the pipe and lot test again. The .7 to .8 groups you're getting right now at 100 is very acceptable for a prs/nrl build, more than capable of a good match showing...the rest is all on you ! Nice rig, good luck and enjoy.
