I have decided to build a purpose built 200 Yard VFS HV. Bullet Central lists Bat Nuevo actions with Right Bolt dual port configuration, with BR/PPC bolt face.
If any of you have one of these, does it truly extract and eject either efficiently?. I want build it it Bart's Grinch to shoot the 80 grn BT, but would like the option of screwing on a BR barrel for 108's.
I talked to Bullet Central, they say no problems. But considering the cost of these actions, I want to be sure.
Jackie, sorry that I have not got around to calling you, I have been snowed under with "stuff" this week. As it turns out, we got our first blizzard here today. Fun.
The PPC/BR BF will extract fine (as Bart stated below). We have made it the default config for a Neuvo going forward but we will do special order PPC BF's as we know many people prefer that based on problems of the past.
I will add at this point that the Neuvo has proven to be a remarkable action. From the initial design the action has shot well barring some teething troubles on the first prototype. We made four small changes to the original design of which only one was necessary. These are incorporated into serial numbers 10 forward. That just shows how well the design had been thought through by the team. And there are many different features in this action that you will not find anywhere else. So considering all that, it has been a tremendous success. I have two of these rifles and I will be taking my prototype Neuvo (#1) to the World Shoot with me next week.
At first we ran into two issues, heavy bolt lift and ejection problems. The problems seem to come and go at the beginning of last year and every time I thought we had solved one of them it recurred.
The ejection problem was easy, the position of the slot for the extractor was a little too far forward and when we changed the extractor dimension the problem disappeared immediately. Although we fixed the original issue we came up with an even better ejection setup in the process which was not necessary but a bonus.
The bolt lift issue was caused because our lug abutments were much wider than a standard action and when the bolt was being unlocked the lugs had to travel across a larger contact area and that caused heavy bolt lift. We lapped an additional angle on to the leading edges of the abutments and that problem went away instantly. Today the bolt lift is smooth and about the same as a DS. The difference is that it is a steadier lift throughout the swing. The Neuvo has a very different feel and I am addicted to it.
We have such good ignition in the Neuvo that people have experimented with 5 pound firing pin springs - that was not a typo - 5 pounds .. and they have shot zeros at 200 yards!! I have not done it myself but this is from confirmed tests done in Australia. Pretty remarkable and that speaks very loudly for the geometry and design of the fire control. I have played with 14 pound springs and they have worked very well. Our current actions are still shipping with 20 pound springs.
Right now Dwight and I can not think of any major improvement to the current design so that speaks volumes. One thing we are wanting to do is perfect the spring used for the ejector. We are still shipping it will a heavy spring and we think that can be improved upon so as customers don't have to dink around tuning their ejection. We have erred on too much is better than too little. The other thing we want to look at next season is choosing a lighter firing pin spring. If these tests continue to reveal what we think then we will likely be issuing Neuvo actions with two springs, a standard 20 pounder and whatever we come up with for an alternative. These will all be available for customers with any serial number.
Most important, if you are a Neuvo customer and you run into any issues, please contact Dwight or I (or the BC office) immediately. We stand by this product and will not leave you stranded. We don't anticipate any issues but we want you to buy with confidence.
Let me know if you have further questions. And I will call you Jackie
