No- it will not feed unless you have an over size chamber, I have one 45 acp I have to size to .451. When you load that bullet the case will swell. Load one and check with your case gauge or take your barrel and do the plunk test. It has to drop in and fit flush with the barrel and have a little wiggle. Then you can worry about feeding. Looking at the bullet it should handle 900 fps without a problem and would be fun to bench rest.
