As all of us that's done any amount of reloading knows, they aren't all this way. But I have an older Model 70 in 30-06 that is just flat ridiculously easy to load for and is just as ridiculously consistent.
The very first load I ever tried with 180 grain hornady interlock flat bases, I quit and didn't go no farther. It plugs them in there every time I shoot them. 045 off the lands.
The 150 load with hornady interlock flat bases took me 3 shots to develop. I loaded one round at 56, one at 56.5, and one at 57. The same .045 off the lands. It put 56 and 56.5 in the same hole measuring just slightly bigger than caliber size, and 57 it put slightly higher so I split the difference on the first 2 and loaded at 56.2 ever since and it simply loves them.
I wanted to try out some 150 gr Speer Hot Cor's I have and never shot so when I checked they contact the lands at the exact same OAL as the 150 Hornady's, so I loaded a couple up to test at the same OAL and the same .045 off the lands and the same 56.2 gr's of powder. No real surprise to me with this gun there's no need to do any farther testing.
I also shot two 180's just to verify there was no difference in a new box of primers I just started. Shot one from the old box, one from the new.
100 yds. Bottom 2 shots are the first 2 shots with the 180's, top target is the next 2 with the Speer 150's.
