Bergara B14R Issues & Solutions
- By 357Max
- All Things Rimfire
- 220 Replies
There are several B14R threads scattered about & I've posted bits here and there.
Thought it would be worthwhile to post a thread geared specifically towards B14R issues & solutions that have worked very well for me.
Issues:
1. Poor or inconsistent feeding especially with aftermarket stocks.
2. Ejectile dysfunction.
3. Excessive cock on close with aftermarket triggers.
4. Hard bolt close.
Going to have to split this into 2 posts since it's picture heavy.
#1 Feeding:
The B14R seems very similar to the Vudoo & Rim x with regards to feeding in that it's basically a controlled round feed. The B14R is very very sensitive to the height at which the round is presented to the chamber. In practical terms what this means is that although it's a 700 footprint, even a .010" mag height deviation (@ the front) via aftermarket stock will cause feeding problems. To explain this a little more in depth it's not just mag height. The mag height in any stock is obviously controlled by the mag catch just in front of the trigger guard. The rounds however are at the opposite end of the AICS SA length mag. So even if the mag catch in your aftermarket stock is at the perfect height; all it takes to muck things up is a slightly bigger magwell (these vary), thus allowing the important end of the mag to drop a little. In my case it is a Manners EH-4 mini chassis that has generous mag clearance allowing the front of mag to dip a little & resulted in shaving or jamming bullets as they chambered. If I held up pressure on front end of mag it fed perfect.
As a side note: Full disclosure the manners actually had a higher mag catch height & I cut a large radius on the top side of my mags to allow them to suck up a little higher to the bottom of the action (thinking this would solve/prevent feed issues). It didn't due to the looser mag well that lets the front of the mag dip down.
My solution for this one is simple and has worked flawlessly for 1250 rounds. I just cut and polished a small feed ramp in the chamber. This could be accomplished with several methods. I used an air powered mini angle die grinder with quality Shars mini carbide flame cutter followed with a shaped felt and polishing rouge. The small ramp makes the B14R & I suspect similar 700 footprint 22 actions much more forgiving of mag height. As a bonus it also makes it pretty insensitive to having your mag bumped up against a barricade. If you attempt this do not get carried away. Small is all you need. If someone were to get a little to aggressive with a big ramp I might worry about case rupture @ the unsupported area on HV rounds.
Below pictures show the ramp & a sample of what I've tested it with to include the highest pressure 22LR rounds I could find. Also pictured is a comparison showing the ramp imprint left on the back of a Norma - Tac 22 LV contrasted with a HV CCI Stinger.
#2 Ejectile dysfunction:
This one has been a common topic in other threads & I'm pretty confident that I've run this to ground. The problem is 2 fold and so is the solution.
My B14R was getting ejection failures at a rate of about 1 in 10-20 (completely unacceptable). The failures were never a failure to extract, but failure to completely eject the spent case leaving it in the action & causing a jam.
The B14R ejection system is comprised of an ejector claw on the port side, a tension claw, & a floating ejector bar.
The first cause of failure happens as the spent case is pulled rearward and catches on the rim of the next round. I played with this on the bench for a while loading a spent case above a loaded case (pictured below). This would sometimes result in the empty getting knocked loose in the chamber before reaching the ejector.
The second cause of failure is due to the mag feed lips. If you look at the picture above you can see the sharp corner of the feed lip in the middle of the loaded round. As you pull a spent case the round below rises up as you pull the spent to the rear. In the above picture the loaded round is blocking the feed lips, but I discovered that as the spent case rim is pulled past that location it can and does catch the lips knocking the case loose before reaching the ejector.
So in both cases the cause is premature ejectile dysfunction.
The video below prior to any modifications you can see the first round is ejected by the mag feed lips. It just so happened that it left the action on this one, but usually it doesn't. The next round you can see it snag on lips first, then rim of next round before finnaly reaching the ejector.

Fixes are 2 fold:
1. Stiffen spring of secondary extractor (tensioner). I used a small piece of an AR15 take down detent spring. Cut too about .070 shorter then tensioner spring, then nested within the stock spring. This eliminates intermittent failed ejections (usually straight up, remaining in the action) caused from contact with rim of shell below in mag.
2. Bevel the front corners of the feed lips in the mag. This guides the extracting shell up and over verses catching and prematurely ejecting in a random direction.
Beveled lips on stock mag & Mack Brothers mag
After mods it's been 100% reliable for 780+ rounds and counting. Edit: Just passed1500 2000 rounds with zero failures.

Finnish Black Jack Competition

- Competition Shooting Talk
- 0 Replies
We do not have a shooting range like you do have in US, in Finland.
And thank´s to EU, these shooting range are like dying dinosaurs.
There is a lead ban talk in the EU in the same time, war is going on on Ukraine, like WTF!
But anyways, i have done one shooting competition up here in Finland, thank´s to
Erik Cortina 500 yards BlackJack challenge.
We do have still some 300-meter range´s in Finland, but only one 500-meter range, that is open for public.
So we need to figure it out, that if we can not shoot 500 yards / 457 meters, which is 0.376 MOA, so we need to make
one with our rules, so we did make the targets smaller, to be equall to the Cortina 500 yard shooting competition.
So we had our first, so called Susiraja Black Jack Challenge competition in the last summe, June 15th.
10-shooters + blind.
2-minutes time, 12 rounds, from the largest to smallest, like Cortina competition.
And we had a blast

And now, there is a new edition made by one Finnish shooter, that
has a little different rules.
Still 300-meters, but 6 plates, 2-minutes and from the biggest to smallest, but if you miss the last, the game is over.
Login to view embedded media
And to let you know, that the smallest target in 300-meters is 3cm / 30mm is equall as 0.348 MOA, and that is just a tiny
bit smaller thant the Cortina target size, but i can sure you, it is not easy.
That´s why i do salute all the guys that has been on Eric Cortina challenge, it aint easy.
And for sure, there is open field, etc, but i am not going to say that we do compete with the Erik Cortina idea, just
want to say that we have made the idea of that, and made the system of our, because shooting
with the accyracy rifle is like making a sex with a VERY beautiful woman
