While the 30-30 is easy to load, if you are using a lever action, at least if you are loading for my lever action, there are significant limitations. My Marlin 336 is a microgroove, I did not slug the barrel.
I shot 170 grain Sierra Round nose over the chronograph to check on velocity. This is not the only group I shot with this load, all groups showed a pattern of vertical stringing. I have tested a lot of powders in this rifle and to date, the best 100 yard group with 170 Hornady FPFB is a five shot group 2.25" in diameter at 100 yards. A grain above or below and the groups are huge, six inches or more is not uncommon. Small changes in velocity result in big changes in point of impact. I found that the chamber headspace is huge , if measured from the shoulder. New cases fall correctly into my Wilson case gage but fired cases are 0.017" above "No Go". To prevent case stretch, which with this much headspace, would most certainly result in case head separations, I am lubing my new cases. This keeps the case sidewalls from adhering to the chamber, and that slides the case to the bolt face. I have adjusted my sizing die so that the shoulder is pushed back about 0.003" after the first firing. The throat is way up the barrel. I tried seating a 170 Hornady long, I was able to feed the round into the magazine and the chamber, but I was unable to extract the round. A loaded round has to be less than the distance from the front of the loading port to the ejector, which is just about 2.550". To extract this round I had to remove the loading lever and pull the bolt out. Unfortunately the throat is so far up the barrel that even with a overly long round, I never touched the rifling.
So for my rifle, the chamber is huge, the throat and the rifling way out there. Because of the huge chamber my loads were about two grains over what a reloading manual gave as maximum loads for the same velocity. I recommend whatever rifle you use, test over a chronograph.
I commented about my problems, frustrations with the accuracy of the thing over lunch with some long range friends; they had been testing equipment that day, their groups at 100 yards were all nickel sized or less, and the basic comment from them was "these rifles are not target rifles " Actually, the precise statements were far more derogatory.
There are 30-30 bolt action rifles, I don't want one as the round is so low velocity, that I don't see the point. For someone who had to have a historic rimmed round in a bolt rifle, the 30-40 Krag would be a better round as you can shoot 220 grain bullets, and is one of the better cartridges for cast bullets. I am of the opinion the 303 Brit would beat the 30-40 Krag with jacketed, but finding a bolt gun in any of these rounds would take some work.
Don’t expect target grade accuracy with a lever action. I conducted a bunch of testing and the best ten shot group was 2.0” and that was exceptional for my rifle. The second best load produced 2.5” group, and I consider groups in the 3 inch range entirely acceptable for a lever action, sometimes factory ammunition gave better groups but I was not shooting ten round groups with factory. Anyone who claims MOA in a lever action will need to produce a 20 shot group before I take their claim seriously.
My rifle shot best with loads that produced the tightest extreme spreads. Also, this rifle shot best at factory velocity loads for the 150 and 170 grain bullets. The second condition is a real limitation for a lever action.
