Having a low power scope to hide heartbeat doesn't mean it isn't there still. I shot NX8 4-32 on both my LR rifles and subscribe to the saying aim small shoot small. Ask 1,000 BRor F- Class guys why they shoot the power they do.
I would rather haver the power and not need it and need it and not have it, if you can shoot say a 24x scope at 500 then a 10x I bet you pick the 24× variable as long as clarity and reticle are equal
