Actually full chisel puts less power requirement on the saw, than semi chisel does.
At least, that's the motivation for running 1.3 mm PS chain, rather than 1.3 mm PM chain, when upgrading from standard PMM with the MS192.
.325" full chisel therefore would put less stress on the saw, and even lesser given it's narrow kerf as well.
The tinier the chain, the faster it's getting dull. And full chisel dulls faster than semi chisel. Therefore, many users rather prefers the .325" over the 3/8 low profile chains.
However, while we are actually using 3/8 low profile PMX chain on our MS362 with 18" bar for milling purposes, we would rather put a .325" chain on a MS241, but better off, instead pick the MS201, which would be equipped with Oregon 91VXL chains on 12" bar.
