Your ATACR will have much better glass than the LRHS2, but the glass is good enough to not hold you back in hunting situations, imo. The real downside of the ATACR is the reticles are not suitable for low magnification without illumination, and can even be a bit tough with it (I’m also not a big fan of the LHT reticle, but like NF it isn’t unusable).
My 3 main hunting rifles have LRHS, LRHS, and LRHS2 for glass, largely because there are so few FFP options with reticles usable on minimum power. I don’t like to rely on illumination for hunting. It’s nice to have as an option, it shouldn’t be a necessity.
Weight is a personal thing, but under 8# all in and recoil can get to be an issue. Most hunters choose big calibers and light rifles; they have no chance of spotting their own impacts. I’ve taken my 11# creed elk hunting in the mountains and aoudad hunting in Texas. 10-12 mile days suck, but it’s doable. It’s much easier to steady and see impacts with. You have to decide what trade-offs are worth it, there’s no free lunch here.
