We thought the same thing, John. We try to go above and beyond with the end-user in mind. Working with experienced shooters, custom rifle builders, and new enthusiast, two things we wanted for our clients was ease of use and customizability. We believe we've done this all while building a Bolt Action at an affordable price. Our team is ready to support you with your next custom rifle build. Reach out to us at sales@pristineactions.com if you have any questions.
Charles must be part gorilla because he makes popping the shroud off look so easy. I’ve got 2 bolt assemblies on my bench and I can’t get them off anywhere near as easy as he shows
Hi Jack, you will have more consistent accurate headspace control if you remove your extractors and ejectors, but we have discovered it is still the correct headspace leaving them in. So no need to remove the ejector/extractors from the bolt head to set the headspace, but you can if you want to. In our next video, we will show how to use the Go gauge with our action when using a Prefit Savage Barrel.
There are a lot of factors to consider with that question. The type of barrel used, caliber used, grain, and the companies that make those products. We know through our test you can easily have an accurate, reliable, and consistent short-action rifle that shoots past 1000 yards. But it all comes down to the parts used, how well the rifle was put together, and the end user. For more information on what components we use, follow us on Facebook and Instagram. There you will find builds done by us and some of our clients.
The rationale for Pristines' 6-lug bolt head, which uses two rows of three locking lugs, ultimately comes down to the necessity of a light bolt lift combined with a smooth bolt throw. WHY TWO ROWS OF THREE LUGS EACH? Safety and increased load-bearing surface. We could use a single internal lug on each side, but then we would only have two lugs bearing the entire 50,000 PSI force generated by your cartridge. Pristines' 6-lug bolt head and 6 matching recoil lugs inside the action spreads that massive load over six times the surface area resulting in far less pressure on each individual load-bearing surface. Less pressure per contact surface means a stronger, more consistent, and ultimately safer design. During our early testing, we discovered the downside of a triple-lug bolt head (three rows of two or three lugs) is a heavier bolt lift resulting bolt lift. A light bolt lift is difficult to achieve with a 60-degree bolt lift. We experimented with the roller wheel cocking piece to see if we could achieve the light bolt lift required but we could not achieve satisfactory results. The firing pin spring must be reset regardless of whether it’s a 60- or 90-degree bolt lift. A 60-degree bolt lift requires more force because the same work is done over a shorter distance. A 90-degree bolt lift allows the maximum lift distance which, in turn, allows the bolt lift to be extremely light. While a lighter firing pin spring would make the bolt lift lighter, the downside - inconsistent primer strikes - is completely unacceptable. That’s why we kept a heavier firing pin spring - to ensure every firing pin strike fully ignites the primer. When the prime isn’t struck with sufficient force, the primer’s ignition won’t be complete, and this impacts how fast your powder burns and differences in bullet speed. Since Pristines' primary goal is to manufacture the most reliable and consistent custom action on the market, we chose to go with the 90-degree bolt lift for a light bolt lift and a silky-smooth bolt slide while keeping the heavier firing pin spring.
@@pristineactions As i know, 3 lock lugs is the main stream design. Steyr SSG08 bolt head is also the same. 60 degree lift up require 1.5x times of 90 degree lift up. Thanks for your explanation.
It's always nice when parts are machined to fit so nicely (and no springs to go flying across the room).

The engineering behind this action is absolutely beautiful!
Thanks for your kind words.
Hi Could you make a video on replacing the extractor.pls
Awesome video and product Bending Ballistics sent me. Glad to be a new subscriber
Hi Chris, Glad you liked the video. Our team worked really hard to make this video happen. We hope to have many more just like it.
Great video and a great action

have two of these actions and neither shroud comes right off
Do you need to remove the ejector/extractors from the bolt head to set the headspace with a Go gauge when swapping barrels?
Hi Jack, you will have more consistent accurate headspace control if you remove your extractors and ejectors, but we have discovered it is still the correct headspace leaving them in. So no need to remove the ejector/extractors from the bolt head to set the headspace, but you can if you want to.

What is the matter of the back of the bullet
How about the accuracy on each calibre?

Yawn. I'll take a Mauser in 7x57 and do it all with the one.
