FROM MY POST ON "YOUR BEST PLINKING LOAD".
I will keep this in the current running thread here.
I want to develop a load using the 230 grain jacketed round nose that moves along around 1500 to 1600 fps. I don't want fast -- I want slow.
There was a recent article about using IMR Trail Boss for reduced loadings in rifle cartridges. This powder was developed for Cowboy Action Shooting. The way the article described how to load -- find where the base of the bullet sits in the case and fill the powder to that point. That is the maximum load. Take 75% of that amount -- that is your starting load. Well I did this using 284 cases and Montana 230 gr round nose bullets seated to 2.10 inches. The amount of powder was 14.4 grains.
I shot 5 of these to see if the action would stay open and it did not -- meaning not enough pressure. I have no idea on the velocity. Since that bullet is .4505 diameter, I am going to try with true .452's to see if they makes any pressure difference and try 450B cases because they hold one more grain of powder.
