That sound of a round fired and hitting the backer is probably a good indicator of a "wonder what this will do" load not being one you want to use again.
When my second box of 250gr LFP turned out to really be (as marked) 200gr LRN, I decided to drop the load on .45 colt just to see how it would do. I have had good results with 7.5-8.2 grains Unique with the 250 gr bullets and haven't really experimented much. I dropped the charge to 6 grain Unique, where I've loaded some .45 ACP 200 gr. Big cases, Lee press and Unique made for some uneven results and probably not suitable for pitty-pat .45 colt. The first round was ~18" below the target X at 15 yards. I managed to get a pretty good group 6" below the X. The rest was trying to figure out on the 3'x3' backer where they hit.
I wouldn't recommend that combination if you want boring, consistent shooting.
