I run a 6-24 PST on my XLR 260. It's MOA/MOA in FFP. I like it for the reticle and zero stop. With an FFP scope there is no reason not to have the higher magnification since the reticle is correct at any mag level. When doing load testing or doing dot drills at 100 yards I like to have it dialled all the way up on 24 to see hits. Shooting steel out to 1000 yards I usually have it dialled back to 16-20 to reduce mirage and limit movement. I just don't see the issue between 4-16 and 6-24 unless you really have a need to dial down to 4 power (and 6 would be too much). Buy an FFP scope and dial to whatever magnification you need. You can never have too much when the need is there.
