Yes.
Also to some degree true for the little .177 calibre, but we really need someone to move something for this little calibre, CUZ it have been forsaken.
Slugs alone i am not sure will be enough.
Not just speaking CUZ my rulers have me chained to this little calibre, i think it is still relevant in my case not least for the cost of ammo VS the larger calibres.
I personally consider 100 M ELR for .177, but with a slight bump in barrel and ammo technology and granted another place to shoot i would be happy to try 150 - 200 M CUZ i do think it can be done, just not with that i got now in the way of barrels and ammo.
I am firmly a slug whore, but i do also shoot pellets now and then on the really calm days.
