You literally just made the same argument everyone else on the thread did.
That 100-150 fps makes not one bit of difference in the field.
Not when both are shooting 125's no. But the .30-30 can drive 150 and 160 grain bullets faster than the 7.62x39 drives 125's. It makes a diffence in penetration and sometimes that matters. If it doesn't, then I just don't get why so many here think they need TSX'S or some such super bullet to kill deer with a .223 when garden variety 55 gr. sp's will kill them just fine.
