The area I was hunting in is along the Columbia River in Oregon, Oregon does not have a power limitation just caliber. I had some other loads I was going to use, but I picked up the wrong magazine.
The loads I had intended to use were with the RCBS 270SAA bullet also at 900+, well above the standard .45 Colt load.
The result was the same.
The .45ACP has always been underloaded, there is a lot of potential there, as long as you stay within the 23K pressure range.
