224 valkyrie muzzle velocity1/12/2024 ![]() I was able to move it at 2700fps in a 20″ 1-7″ barrel without issue. ![]() 22 caliber cartridge that can shoot a 90gr effectively.īack when I shot competitive High Power Service Rifle, my go to bullet for the slow fire prone stages was the Berger 80gr VLD. Yet, I still have the yearning to at least get into a. So even though I have an American Rifle Company Nucleus action that still needs to be built, I decided against 22 Creedmoor (or 224 Valkyrie) for that bolt action. But this uncertainty seems like a moderate to high risk for me in terms of expending time and money to build a bolt rifle for such a chambering. Of course, I read all the stories of people who have built 22 Creedmoor rifles and are pushing the 90gr bullets at 3000fps and higher without issue. Limiting that muzzle velocity defeats the purpose of going with a larger base/parent case and necking down to. In order to stay under this supposed 300K RPM rule, that would mean staying at 2700fps in a 1-6.5″ twist barrel. If you decide to go with a 1 in 6.5″ twist barrel, the RPM spikes:įor me, the whole point of moving up to something like a 22 Creedmoor is to get the 90gr SMK or VLD moving extremely fast to take advantage of the bullet’s ballistic coefficient and maximize efficiency of the bullet. When I was looking at 22 Creedmoor, I saw people posting incredible muzzle velocities above 3000 feet per second with a 90gr SMK or VLD.Īssuming, 3000 fps in a 1 in 7″ barrel, that would come out to ~308,571 RPM. The quick formula for calculating the RPM of a bullet is:īullet RPM = MuzzleVelocity * 720 / Twist Rate (in inches) 22 caliber bullets, the likelihood of jacket separation in flight is significantly increased. This figure basically alluded to a 300,000 RPM threshold for bullets, particularly. I ended up coming across a post by a prominent figure in the shooting industry whose expertise in ballistics is highly regarded. The jackets would separate from the lead core in mid-flight. The issue is that some people have been able to spin jackets off of the heavy 90gr Sierra Match King and Berger VLD bullets. 22 caliber cartridges, specifically bullet jacket instability. 223 Remington and 224 Valkyrie because of the high speeds that 22 Creedmoor is capable of.īut then I started reading up on the sporadic issues some people have had with the new high speed. Later on, I came across 22 Creedmoor which is basically the 6.5mm Creedmoor parent case necked down to. 223 Remington bolt rifle with a high twist barrel to shoot 90gr bullets, so I started looking at 224 Valkyrie. ![]() I had been recently pondering building a.
