Hypothetical Rifle Load?
Hypothetically, let's say that I'm working on a wildcat load.
Please assume the load was originally developed with a powder with a similar burn rate to BE.
The original specs are thus:
40gn lead bullet, BC about .132
.224 caliber, seated depth only .10-.13"
3.1gn water capacity
1.5gn fast (BE-like) powder charge, small pistol primer
COL of .985" +/- .005"
Claimed velocity of 1230fps
Firearm is a rifle, 21" barrel.
Now, let's say that the load were worked up to the same specs, except that the powder charge was 2.0gn of W231 to take advantage of the longer burn time afforded by the longer barrel.
What would you expect from such a load? Velocity, etc?
