First time trying Swiss 3f in my .45 swamped rice barrel Bob Ray custom rifle. Interestingly to me, I got nearly the same placement with 65g of Goex 3f and Swiss. As I lowered the charge of Swiss I got a higher POI, that seemed counter-intuitive. At 50 it started to drop again and at 45 was basically at the same POI as when I started. The high shot on the 45g target was a haaaaaaang fire. The rifle's load of 65g 3f Goex was originally determined after a good amount of work at the range when this rifle was new. I shot to get the best group with the highest POI using the lowest charge that would achieve those results. Maybe someone can explain to me why a lower load would achieve a higher POI. I will be doing further testing next time at the range.
