southtexas,
Based on my experience you left the questioner hanging. I discovered from experimentation even a 1/16 of a turn will make a difference once you get close to the correct spot.
Is this your experience?
Actually, the adjustments can be even smaller than that when fine tuning. I recorded several .2-3" groups under range conditions with hunting scopes but again, I could not replicate that level of accuracy in all 4 rifles shot over perhaps a year total under the same range conditions.
The cartridges I reviewed included:
.270 in a Browning A Bolt.
.22/250 Browning A Bolt Heavy Barrel.
.308 in Browning Auto
.270 Model 70 Stainless.
I tried a lot of loads to find accuracy and then fine tuned it. To test the BOSS unit for its individual benefit, I would likely load a Sierra bullet in a moderate load and let the rifle do the work from there.
