Figured it out. I took a shot again and it was dead in the bulls eye after i adjusted the sights, Swabbed and shot again, 4" low! Went inside to get a drink and cool down and load up another speed loader, this time with a powerbelt, went and loaded it up on a dirty bore, Hit dead on where i was aiming and dead center. It appears its just the heat thats throwing off the bullets. Im done at 50 and later this evening i will pull back to 75 yards and take a couple shots there and hopefully get it out to 100 yards today. The 348 gn powerbelts seem to be another good choice for me to try out some time.
I found a 410 gn great plains around my backstop and i got the load just right. Its a perfect mushroom without any holes. I think 90 grns would drive them to fash and expolode them.
