Five rounds of ammunition will be fired at each barrel length and the velocity and standard deviation recorded using.
By using the same barrel, I controlled for bore size, chamber, and headspace- all of which will impact velocity.When properly placed, this bullet size can effectively drop a whitetail deer and many other medium-sized game animals.1300 West Henry, sedalia, Missouri, 65301, mailing Address.Modifications to a firearm may result in personal injury or death, cause the firearm to not function properly, or malfunction, and cause the firearm to become unsafe.Speed, however, goes to the.243, which has cartridges rated over 4,000 feet per second in muzzle velocity; the.308 usually maxes out at about 3,100 feet per second. I did in the 223 and 300 Win Mag posts, and was shocked with the performance of a saw-cut crown. Overbore cartridges tend to be characterized by high muzzle velocities, use of slower burning powders, longer barrels and relatively short barrel life due to throat erosion.This test controlled for the barrel, which, in my opinion, is better than comparing velocities between different rifles with different barrel lengths. Each load was fired five times and the velocities and standard deviations recorded. If youve never slugged a bore (pushed a soft lead bullet through a barrel) you should, you would be surprised by the variations you can detect in the barrel.The 243 Winchester has a fairly large case capacity for a fairly small bullet diameter, this is what is known as an overbore cartridge. If they did, heavy metal fan gifts I would have noticed the first round fired for every barrel length slower then the subsequent rounds.Remington 700 receiver and the final head space measured.633, which.003 above saami minimum head space specification. At 16, velocity was 2806 feet/second, a reduction of 317 feet/second. As mentioned above, I agree with sample size. My lathe is a two hour round trip to the range.Category home, rifle Ammo.300 Win Mag.300 Win Mag, rifle Ammo.300 Win Mag, sort by -Price: Lowest firstPrice: Highest firstProduct Name: A to ZProduct Name: Z to AIn stockPrice per Round: Lowest firstPrice per Round: Highest first.Considering that the.243 Winchester was based on the.308 Winchester cartridge, its easy to compare and contrast the two.How Far Can You Accurately Shoot with.243 Winchester?
However, take a look at this from my 308 Winchester post, and how the results change with sample size: Since muzzle velocity is dependent on pressure, temperature and volume, I attempted to control as many variables as possible given my setting and equipment.
