Thread: Reloading conundrum - time constraint.

If it were me, i would set 5 rounds at .05" off the lands (or more). All this '.01" off the lands' is commonly used for VLD's for long range shooting (IMO) but it appears to stem from the BR crowd. I just don't reckon its the optimum solution. I'm not calling the .01" thing a myth, but i do question any given rifle's ability to actually keep this setting over a full day of competition.
Wouldn't throat erosion introduce a greater variation percentage, say .005" erosion loss of the lands themselves (over 200 shots taken) so that's 50% of .01". However that same loss vs the .05" setting is only 10%. Even if i'm way out on the erosion rate, that ratio WILL be right no?
That's my muddled reasoning for the graph below

These clearly show a stability window for projectiles seated further back.
