At the other end of the spectrum are 5. Sometimes, even 5. In between are chambers designed to balance pressure and accuracy, for the long freebore and throat dimensions of 5. These include. What all of these chambers have in common with the exception of the Noveske chamber, which is produced by only one shop is that they are reamed by a wide variety of machine shops and personnel who may or may not be experienced, skilled, or caring.
When you buy, for example, a. If it was made by a company with more of an emphasis on cost savings than exact machining, it could be a minimum spec. Even between chambers reamed by a reputable company, differences exist, as you will see. In addition, the pressures of different types of ammunition can vary wildly — this is, like many things I mention in this article, a topic for another day, but I saw pressures between 45, and 63,psi while conducting this testing. Summary: Instead of there being two or three or four possible chambers.
This can result in differing pressures with the same ammunition. In order to test how 5. The Weatherby Vanguard Compact. However, I felt that it was better to test a large amount of ammunition in a few rifles than only a few rounds in a large amount of rifles the results were still quite educational. Read more about 5. Because of their consistency, and because. In essence, it is required to use a load of known pressure to calibrate the equipment and provide a useful comparison with any other type of ammunition or chamber.
How the strain gauge comparison can be useful is to see what increases in pressure result from the use of different types of ammunition in each chamber compared to that calibration load. If we eliminate other variables and see a massive increase in chamber pressure from. In order to ensure that I was getting the most accurate maximum average pressures possible, I contacted the manufacturers of a number of different types of ammunition with the results I had found. Of the manufacturers that responded, none informed me that my maximum pressure results were inaccurate although they were understandably reluctant to disclose their proprietary data.
Summary: I tested. I know most people are interested in this part — and yes, I really did fire 5. I had a friend at the range with me at the time, and he stayed a good ways back when I did so. I was not concerned about what would happen, and as I expected, the results were not spectacular. However, I was surprised about the results I saw.
There was no dangerous spike in pressure from firing 5. While pressures were elevated in comparison to one of the 5. This unexpected difference was also borne out by chronograph measurements, which showed that the Weatherby Vanguard Compact bolt action rifle fired the XM ammunition all of which was from the same lot at a velocity which was higher than the lower pressure 5.
The 7. Winchester copied the round and named it. I suppose a standardized military round creates a specific ingredient, whereas commercial ammo has more flexibility with their loads. It just so happend that the military load for 7. This is a reason to get 5. That way you can get either 5.
You get the best of both world. I have a 5. I save my 5. From time to time Walmart sells 5. They probably got some metal in the lead.
Lead was expensive a little while ago. I think they called it bi-metal or something like that. Where did you get this price? This is the info I got from some competition shooters I know.
Wylde was not designed to be used with both 5. To be able to load them hot they made the chamber able to fit 5. So they will not be as accurate with 5. Due to this it was not designed to use both ammo types but special hand loaded ammo, being able to use both ammo types was a side affect but will not be as accurate with them as a 5. I dont even think ive seen for sale ever, not even at gun shows or at stores.
Everything is always Ive always shot outa my AR, no accuracy issues, i only shoot a couple hundred yards max. Hmmm, the Ruger Mini I own is chambered in 5. I suspect that was done in when they redesigned the system. My two pres Minis are stamped. I have read and completely agree on everything. As stated above, always refer to your barrel for the proper cartridge use in your firearm.
After calling Weatherby, they told me NOT to fire the 7. Both made reference to catastrophic damage possible. Basically due to how the pressure was measured, one using CUP [Copper Units of Pressure] and the other using a different method.
Both resulted in unacceptable possibilities of failure. Is there an available rifle that can fire both? Please help!! That said, the case of the. Generally speaking, a.
Hope this helps. Are you trying to learn the difference between the. Is the same difference existing between. John Reply. Good article. Great article.
Thanks in advance for any input.
