It might not be a competition round, but it is fun to mess around with while on the range with friends. The downside to the lightweight rounds is going to be the low BC which is useful when firing at these long ranges where wind really becomes a factor. And this makes sense after looking at how the .243 rounds bled velocity at a higher rate and have lower BCs than the 6mm Creedmoor rounds. The following ammunition cartridge ballistics information and chart can be used to approximately compare .22-250 Remington vs .243 Winchester ammo rounds. F&S Classics: Lost Soul. Give a Gift   We also saw that the 6mm CM rounds maintained their velocity at a better rate than the .243 rounds which is a good indicator that the flight is stable in most aspects.

So, we gathered the short range trajectory data from the manufacturer where available, and also use a ballistic software to generate data as well. A lot of different variables go into calculating a bullets BC but it, along with velocity, are big factors in the how the bullets trajectory and wind drift behave. We take the stance that none of these categories are great for determining stopping power when isolated. a run for its money due to its superb accuracy.

Its roots pre-date the 1950s, though 6mms had little support in the early years of bolt rifl… We can switch it up with different bullet mass as well. We do recommend digging into the BC and how it is derived. These three products from Horus Vision, a smartphone app, pocket weather meter and laser... Rifle Shooter Digital Staff - April 23, 2019. ©2020 Outdoor Sportsman Group.

A lot goes into a bullet’s trajectory including bullet specs as well as environmental characteristics. Now, there are many other factors that go into a bullets ability to drop animals cleanly, such as the bullet design and its ability to cause serious wounds based on how the bullet expands when it reaches the target, but that’s hard to quantify and have any meaning when trying to compare two cartridge types. Further it could be loaded with full-length bullets and still function in an AR-10, so there were more options for competitive rifle platforms.

It’s not quite the same as the actual felt recoil that you feel, but increased recoil energy does correlate with increased felt recoil. For factory loads, both of these cartridges are excellent choices for target shooting. We just think that it is important to consider if you are deciding between two cartridges to not focus in on one individual performance spec for the basis of your decision. The trajectory is one of the most discussed ballistic properties when it comes to discussing the performance between different rounds as well as between two different cartridges. in 1955, the same year Disneyland opened, gas cost 23 cents per gallon and we launched the world’s first nuclear submarine.
