"After many decades (100 plus years!) of loading the 30-30, ammo companies have it right."
Agree - long term familiarity with the cartridge, coupled with modest muzzle velocity, seems to lead to some really nice performance. My other favorite .30's are the .308 Win & .30-06, they too benefit from much cartridge & bullet development work.
Mentioned to my son last night that bear season opens again in a bit over three months, and he got all excited! Maybe the .30-30 will tag along with one of us while we're hunting...
