It,s real common for BT,s and accubonds seated .050 and even .100 off the lands and still shoot tiny little clusters. The absolute longest I load and still fit the mag is 3.420. Therefore I use 3.400 coal for accubonds and BT,s. So for me I cannot get anywhere near the lands while accuracy with those polymer tips remains very accurate. On the other hand I have a 300 mag. 700 BDL that has a generous mag. that allows me to load a 180 accubond at .015 off the lands. Again accuracy is incredible. Myself I never load any closer to the lands than .015. I,m just not compfortable with closer. At .015 to .020 off the lands I,ve never had any pressure problems with loads that are not already too hot. As always start low and work up.
