I agree with everything said so far. Your typical 30-30 will be a lever action with a tubular magazine under the barrel. Because the ammo goes in bullet to primer a solid hit will set off a chain fire under the barrel and blow the gun up. To eliminate this the only factory loads are going to be a jacketed soft point of some variety so that the round deform again the next rather than setting each other off. When hand loaded the 30-30 shines. It's still no long range plains gun but it picks up speed quickly as bullets get lighter, better, and more aerodynamic. 2500 is no slouch in velocity and I feel like there's plenty room to improve upon that even.
30-30 was the parent cartridge to several wildcats as well. I have a 7-30 waters which is a 30-30 case necked down to accept a .284 bullet, and when fire formed the shoulder moves forward a bit. It is supposedly better than 30-30 at everything but it never caught on. There is also some 22,25,30,32, and 35 caliber wildcats which I have heard of from the 30-30 case as well as 6mm, 6.5mm, and other 7mm wildcats.
For home defense the gun is wonderful. Compact, handy, and quick. Not lightning fast but fast enough to have the gun back on target and firing before the first round is answered by any reaction. More than enough gun to serve that purpose.
A very select few handguns have been chambered in the 30-30. They are all large framed and relatively heavy. Suprisingly the handguns are not that bad on recoil.
