Iron sights on most handguns sit just above the top of the barrel and therefore the line of sight is a short, but variable (depending on the specific model of handgun), distance above the axis of the bore. When it comes to cartridges and bullets, one of the most argued topics in the previous decades was .45ACP vs 9mm Luger (aka 9×19). ). point of impact, but higher velocity flattens trajectory, decreasing bullet This tissue is usually dead due to the hydrostatic pressures induced. Been testing some of my Hi-Tek coated rifle bullets to see what level of velocity they would take. Wind and the way it behaves in a given environment is out of the shooter’s control. Velocity is classified as low (<1000 fps), medium (1000 to 2000 fps), and high (>2000 fps). First time trying low velocity .22 rounds and was amazed at how quiet they were. A Those who advocate for a lighter but faster bullet will point to the fact that the formula for kinetic energy is 0.5mv^2 (1/2 of the mass x the square of the velocity); meaning that a lighter bullet at a higher speed will carry more kinetic energy than a heavier bullet at lower speeds. So much so that ammo types have been added into the game. The Effects of Bullet Weight, Velocity and Trajectory on Point of Impact. I read that the longer the barrel the greater the velocity of the shell. No arsenic added. Linotype will gain about 50% more hardness, where some high arsenic content alloys will be closer to 100% gain when oven heat treated at just below the melt point of the alloy. relation to the bore axis. Trial and error with a variety of factory loads You are at a gateway to WWII discussion, research, exploration, & analysis. In the early 2000’s as people began adopting cartridges other than .308 Winchester for precision and/or long range use, people tended to favor the highest BC bullet available and usable in the given cartridge. This is particularly important to know when dealing with a handgun that has fixed sights. If you know for a fact that a given target is 1000 yards away (e.g. But advancements in bullet designs have also brought up this debate, albeit in a different context, within the realm of precision rifle and long range shooting. You would much rather have the Berger 140gr load for the higher BC and wind resistance. A heavier bullet at the same velocity generates more recoil and muzzle flip, raising the point of impact. I also have the tests from the early 1900s where the .45 pistol round was picked after the Army tested it against live animals and human cadavers in Chicago. Springfield Armory Introduces XD-M Elite 3.8″ Compact. The 2900fps muzzle velocity of the G7 BC of .287 also yields a respectable trajectory when through a ballistic calculator. I have a question, WHY are you seeking such high velocity? All rights reserved. Jim R. Lv 7. Originally John Browning designed his pistol which was going to become the 1911 with a slightly lower bullet weight, but the Army demanded the 230 grains, so he obliged and increased it from 200, his original bullet weight. Copyright 2013, 2016 by Chuck Hawks. May 6, 2015 High-Velocity Shooting: Pros and Cons. But this was of course years before the first "Tommy gun" was even produced. I first started off with the 140gr Hybrid Target because it had one of highest ballistic coefficient values advertised with a G7 BC of .311. You are one of the few that have posted on running painted boolits at high velocity in a rifle. I was able to achieve a good 6.5 Creedmoor load with the 140gr Hybrid Target that pushed it with a muzzle velocity of 2750fps. I was able to easily push the 130gr AR Hybrid at 2900fps and could hit 2930fps without any severe pressure signs. usually load lighter bullets to higher velocity in a given cartridge. Changing bullet weight while maintaining the same I have had mixed results using softer BHN alloys then heat treating then and then baking the coating. I am using the Berger Bullets 6.5mm 130gr AR Hybrid OTM Tactical as my primary load for my 6.5 Creedmoor rifle: For more information on the Berger Bullets 6.5mm 130gr AR Hybrid OTM Tactical, read the Berger Bullets press release for this bullet when it was released in 2015. High Velocity Bullet. The sight line very slightly converges with the line of the bore, crossing at some distance down range. Reproduction in whole or in part without permission is prohibited. (The amount of powder used, while usually not as important as bullet weight, There are also times where the target could be moving towards or away from the shooter resulting in a variable distance condition. Did Dirty Harry Use .44 Specials in his Model 29?! With a lighter (shorter) bullet in that same cartridge, you can get more case capacity for the powder. Haven't tried it yet in my Contender 223 Rem but I was shooting at about 2,700 fps. 2.260″ for the AR-15). Generally, a 140gr bullet in 6.5mm Creedmoor is moving with a muzzle velocity of 2700fps (sometimes higher with custom handloads) out of a 24″ barrel. But why is the flat trajectory of the Berger 130gr AR Hybrid (2900fps MV) more advantageous than the Berger 140gr Hybrid Target (2750fps MV)? Excuse my ignorance as I have just started to read more in depth about weaponary. As an Amazon Associate, this site earns from qualifying purchases. However, we have concluded the following: The guiding principles behind these generalities are: What are the practical implications of this? This velocity with the G7 BC of .311 yields a highly respectable trajectory when run through a ballistic calculator. Any attempt to change the point of bullet impact by changing Traditionalists argued that the .45ACP with a heavier 230gr bullet moving at a relatively slow ~830 feet per second made for better stopping power than the 9×19’s lighter 115gr / 124gr bullet moving at ~1200 fps. raising the point of impact, but the heavier bullet usually exits the muzzle at It is up to the shooter to decide which fits the given environment and shooting style. Well, it all depends and this is where the debate begins. Many products featured on this site were editorially chosen. Unless attributed to the respective copyright holder, all photos and images are property of ocabj.net | JOCAB Media. "Bator" bullet and did some testing with it. Please Wait. Thats what the did with the Thompson. muzzle velocity 350-650 meters per second or 1,200-2,000 feet per second; shotgun blasts. Does that mean its barrel was lengthened? crucial factor is the firmness of the shooter's grip. Welcome to the WWII Forums! The bullet simply could not cut through the air and maintain stable supersonic flight to 1000 yards with regularity. is absolutely critical to maintaining a consistent point of impact with any The Beginner’s Guide to Birding in the U.S. How to Hunt Whitetail Deer During the Rut’s Chasing Phase. But trying to push any further can result in higher pressures with decreased case life or even dangerous conditions. A low velocity 105mm howitzer. 0 0. Sturmgeschütz III and the article was talking aobut how its' 75mm went from a low velocity to a high velocity weapon. Do you pick a slow and heavy bullet or the fast and light for handgun use? Source(s): https://shrinkurl.im/a8jnC. © Specialty Pistols 2003 - 2019 All Rights Reserved. The argument for the lighter and faster bullet is that there are times where you cannot use a laser rangefinder and must use other means to range the target. Bottom line is the answer is that it all depends, on velocity at time of impact and caliber of specific rounds being compared. I have been a proponent of Berger Bullets ever since I started using the Berger Bullets 22cal 80gr VLD in the AR-15 for High Power Service Rifle competition (on the 600 yard line). Sierra Match King) was the bullet most people shot. Other ~140gr bullets such as the Sierra Match King 6.5mm 142gr and the Berger 140gr Hybrid Target with high BCs are also quite popular in the 140gr family.
