Boy, some bubbles are a degree or two off here and extreme accuracy reloading inexperience is really showing.
Maybe the Berger people can take lessons too! Must be a full moon or something.
If all you want is MOA then, hell throw any load together with any bullet, any powder in custom barrel and you have it, at least 99.9% of the time. Most here, particuliarly anyone shooting at LR, better be working for a load well under MOA or stick to 300 yds and less.
For the uninformed, the ONLY way a bullet .020 into the lands comes out of the case is if you are running neck tension of .0015 or less and you deserve the dumb butt award for doing that in a hunting gun.
For hunting rounds, particularily in a mag gun, you want at least .003-.004 neck tension, otherwise the bullet will often "move" out while in the mag due to recoil.
FYI also, "jamming or soft seating" a bullet will normally result in .040-.060 into the lands not .020. That is a technique often used in single shot comp guns to define a starting point, and we have found that as deep as .030-.040 is the most accurate spot many times.
As for never putting into the lands, depends on your throat and what your gun likes. If it is a standard way too long factory, you will never reach the throat in a mag gun anyway.
Now if you have a custom barrel and chamber that used a reamer properly setup, you can routinely get close to the lands if not touching, just depends on how the reamer was set and for what bullet. Experienced LR guys routinely use reamers made to do that both for comp and hunting guns. Just have to have the reamer make set it up that way.
Every gun is different, and really naive IMO to think that because one gun likes .020 or .125 off, all others will too and that is where to start. Just where do you go if it does not like it?
IMO also really stupid to start in the middle and then come off and then then go back and go towards the lands. Hey, but nothing more than time, bullets, powder and barrel life so go for it.
As I said, you would be smart to start at your max mag OAL or no more than .020 into the lands IF you can reach the lands with max mag OAL.
Have a system instead of hop scotching around!
