I shot an entire box of Remington Ultra 180 gr Nosler Partitons when I bought the gun, I couldnt hit a basketball at 100 yrds if I wanted to with them. So I called Bigcountry, and he searched through some of his data, and said "try 93 gr of H1000" so I pressed up 93,94 and 95 after 6 shots of the 93 and could cover all 6 with a golf ball I pulled the rest of the loads and made a whole bunch of the 93's. One side note, the p.o.i switching from the factories to my handloads was 8" higher!!! Sometimes you just get lucky. Also I got lucky and found someone to buy my other box of factory ammo for the same price I paid for it!!
