How do you all feel about this chamber job?

The idea is that "cold bore" shift is really caused by difference in friction; basically after you fire a shot tiny amounts of condensation cling to the bore and change the friction of the next shot enough to shift point of impact. Josh (Persuit of Accuracy) has a funny video testing this where he primes the barrel by blowing into it with a soda straw before firing his first shot. His chrono and impact data showed that it did in fact make a difference. Since most of us aren't going to blow down the barrel at Make Ready the next best thing is using something to keep the air from getting down the barrel and drying things out. Muzzle protection devices made for paintball guns are good for this. Full disclosure I haven't tried this myself, I got something to test it with but I'm barely able to keep my chit in order during a match to begin with so I can't remember to cap my muzzle!
I have another match in a few weeks, but I'll contact customer service after that to see about sending mine in as well. Hopefully they turn around replacements quickly!Well sent mine in yesterday. So the wait begins. The rimfire thread tagged above shows a guy with same issue. Sent in and 7 weeks later received two brand new flawless barreled actions back. So hopefully that’s the case with those of us taking the initiative to address the problem
I really want to love my bergaras. I like my 18” and was hoping my 20” would be even better and I would build a 24” off the 18” action.
Should things go sideways id just sell and find a Rimx or one of the newer actions to build on. But ideally I’d like to run a custom Bergara and a 20” hvy factory for my setups. Mags haven’t given me issues (other than one mag that was worn which I bought used) that’s in the factory stock, MDT and MPA chassis
Fingers crossed
I can say my initial contact with Bergara, email exchange and my photos I sent in were great customer service. Very prompt responses and so far zero delay or run around. Initial contact to them setting up a label for return was probably less than an hour
It’s a good test in today’s market for Bergara. I’m sure a lot of members or non members will come across these threads when purchasing a rimfire. It’s been referred to as “poor man’s Vudoo”. With Vudoo essentially out of the picture at least for now I’d assume the Bergara sales crept up a little bit.
They play in a dangerous price point in my opinion if you send out barrels like this and don’t make it right. Especially in the current market for CZ 457’s. Once you factor $850-$900 for a barreled action that will need a trigger upgrade you’re around $1100.
From the cheap end you can do a 457.
On the opposite side of the spectrum if you had this barreled action Bergara sitting on the shelf and I bore scoped it before buying I would just opt for a rimx action instead.
I’d compare it to 2010 where you bought a savage for cheap. If it didn’t impress you it was a “so what” and you rebarreled it inside your garage. But you bought the gun for $450 and an action alone was $350 on the used market. So you weren’t out much and could dump the barrel for $100
For the battlehawk armory deal which was $640 it’s not a terrible gamble. But when you start creeping up to the $1k mark with the chance of just using the action it becomes a bit more of a challenge to decide between that or $1150 for a rimx
I have tested it too with my MTR and the results were spot on. No cold bore flier if capped or with a straw blowing down the chamber for a 5 count. A 10 count actually slowed that first round down, so there is clearly something going on.
In most matches, I will drop down to prone or lock my rifle into my tripod to check parallax when I’m on deck. I carry a straw in my kit if I forget to cap the gun, which is nearly impossible (my cap is attached to my chamber flag with a tether - so one goes on, and so does the other).
Not all of my rifles have that pop, but the factory MTR does for sure. That’s what I tested.
