I load my 30-30 with 125 grain HP from 2150 fps to 2550 fps. Let me tell you also that I own a Ruger SBH that shoots MO Cast Bullet Keith 240 grain Lead. I am fimiliar with both calibers. Although one is pistol and the other rifle, but I think that the 125 grain HP from a 30-30 in the velocity range I have mentioned is a deadly deer getter. I know it is. When I stopped using 150-170 fp/rn bullets, and switched to these. The tracking deer stopped.
I am looking for a .44 Stainless 1864 to match my Ruger, but just for looks and fun. If I want to go serious with a lever gun, I choose the 30-30 with my hand loads using Sierra 125 grain HPs, and the party is over for whatever I take aim on.
What I am saying is you can make the 30-30 whatever you want it to be. Lead with pistol powder, lighter rounds at blazing speed with a 110 Speer HP and H335 for a 2650 fps laser beam, a super duper .30 cal using IMR3031/H4895/IMR4895/VVN120 using the 125 grain Sierra HP, or you can shoot the good old 170 grain Winchester Silver Tips to the classic 170 grain Federals which are a great and accurate bullet.
Take a 12 gauge 00 buck shot ball with pistol powder, and you have a plinker on the real cheap.
The 30-30 is a much more versatile rifle than the .44 Mag (Pistol Cartridge) out of a rifle.
From my calculations you can load the 30-30 with bullet weights from 53.8 gr to 190 grains. Kinda like the good old 30-06. You just gotta have the means and know how to do it.
