Bergara B14R build

My CZ with the lilja barrel shoots just about .40-.42 with SK match red. You might try some of that ammo

So I've taken both Bergara and CZ out several times. Haven't been able to find center x, but I did find a case of SK rifle match and for poops & giggles, a few boxes of biathlon.

CZ didn't really like the SK match (right side), but Bergara shot some better groups (left side). Toward the end, I tried biathlon with the CZ and I shot the best groups ever (3U). All 5 shot groups @ 50 yards.



Below is second time with SK rifle match & Bergara. A couple groups to get settled and then better results (not sure what happed with 1 flyer).

CZ still seems to like biathlon. Able to get consistent hits out to 307 yards (small hanging pig at ASR).

Finally got ahold of some center x.

Middle circle first 5 shot group. Cold bore shot about 1" to the right then next 4 shots grouped ok. Next 5 shot group (top right) was probably the best 5 shot group with the Bergara.

Top and bottom left center x with CZ. It still seems to like SK Biathlon (middle left).

It took a while, but finally managed to find some Tenex. I was told by a fellow shooter that Bergara w/CF barrel seems to like Tenex so I've been trying to locate some for a while. Tried it out and sure enough I was able to get some decent groups so I ordered a few bricks and went out yesterday.

I confirmed zero @ 50 yards and then took it out to 300 & 400 yards and then back to 100 yards (66.25 MOA of elevation at 400 yards...that equates to over 1600 yards w/6 creed).

Each pic includes a 5 shot group @ 50 yards and then a 10 shot group at 100. 1.65 MOA is disappointing, but 0.9 MOA gives me hope that this rifle isn't a bust so I'll keep at it.

If you want ammo that shoots tight groups in your gun, you should make the trip out to Mesa and have your rifles tested in the tunnel and just buy a couple cases of that ammo from Lapua. That way you're not worrying every time you buy a brick of ammo hoping that lot shoots well for you.

If you're wanting to shoot extended distance, you should be using a chronograph during your testing so you can get the SD. It'll matter quite a bit when you stretch it to 300 and out.

Interesting. I use chronographs when I try new rifles/ammo, but not so much for rimfire. I just usually zero at 50 yards and then true at 300 yards (actually 307 yards at ASR) to calculate velocity. Seems to work ok, but it's probably not as accurate.

I was (almost) today years old when I did some lot testing using a chronograph.

Good news is one of my Center X lots had 4.8 SD (20 shot groups) and when I shot it at 100 yards, it produced about 1" groups.

Bad news is what do I do with lots that don't do as well? SD isn't going to change because I shoot from a different rifle, right?

I prefer to take this rifle for hunting. The bolt-action, manually operated, bolt-action, rotary bolt-action rifle is designed for practice and practice. It replicates the geometry of the popular Remington 700 rifle platform and its mounting standards for stock, mounting bases, and triggers. This opens up many modification possibilities, and the single-row magazine is in the standard AICS format. That's why I bought this rifle https://walkeroutdoors.net/product/bergara-bxr-22lr-semi-auto/. Practice with this rifle is much cheaper and less tiring, allowing for more shooting and technique work while not being limited to finding a significant rifle range.
