Thanks for the comments everyone. Seems like there's not a whole lot of information out there on the topic. I believe either way you go - barrel band or swivel stud screw - accuracy is going to suffer a little. My 99F is very sensitive to how much you tighten the forend screw. The sweet spot seems to be 3/8 of a turn off of snug. I've got a target laying around somewhere with subsequent groups fired backing off 1/8 turn each group. Groups went from 2" at 100 yards to one jagged hole at 3/8 turn from snug. There was a very noticeable change in point of impact with each group as well. If I can find it, I'll take a picture and post it. I'm hoping the swivel stud screw will line up close to the sweet spot and I can lock-tite it in place - problem solved. I've also heard of accuracy "tuning" with a barrel band so maybe that would be an option too, but it might difficult having to readjust the position given the crappy metal in the newer Made-in-China Uncle Mike's barrel bands.
