This has been my go-to load for my M36 for a while now. For me, it feels as if the recoil is a little less than your average 158 grn LRN. They may be pushing the envelope, but they're standard pressure. Check their specs against the BB +P 158-grn rounds and you'll see the difference.
For what it's worth, I also find them to be extremely accurate -- almost on par with my 148grn wadcutters -- probably because of the soft lead.
