First off, welcome to THR !
Second off, welcome to Reloading !
It can be intimidating at first, but is very worthwhile.
In regards to your model 94, .30-30 is a great cartridge to start reloading for.
Its rimmed, its pressure tolerances are good, and the handiwork required in full-length resizing and trimming your brass at each loading for a levergun is fantastic practice.
With regards to loads, I have used your core-lokt bullets, sierra, as well as hornady, speer and a few others from 150 grains up to 180 grains. I have utilized all of these bullets up and down the charge spectrum using H4895, h335, and IMR-4198.
I use a Hodgdons reloading manual, as I find it easy to reference both online and offline in paper form. You may wish to obtain data from a number of sources and manuals. One can never have too many, but sometimes the loading data between them ( often ) does not correlate, and can be confusing to the beginner in that aspect. With that in mind, as a beginner, you may wish to settle on one for simplicity....other users here may have a different viewpoint.
Hodgdons data is available on their website in a format that is easy to reference while at the PC, and copy and paste where appropriate in forums, or in my notes.
You will receive many recommendations here on bullet weight and type, and powder weight and type. Where does that leave you ? What will inevitably be best is what is best for you, your reloading habits, your component availability, and most importantly what works best in your rifle(s).
My favorite load ( one that performs well in this rifle, repeatably, in all weather conditions, and uses a powder which I use in other cartridge loadings for its universal characteristics and weather resistant properties) for the .30-30 is as follows:
150gr Sierra FN (bullet)
31 grains H4895 ( Charge weight of powder type)
CCI LRP (primer)
2.540 COAL ( Combined Overall Length )
In general, it is often referenced that seating for the .30-30 is acceptable anywhere within the cannelure of the bullet. This is generally true, as it allows for even and easy to place crimp. You may find that in your rifle, some experimentation may be required to achieve the best accuracy.
I wish you the best of luck in this most excellent of endeavors, and implore you to return with any questions you may have !
edit :
I got carried away and forgot to answer probably your most important question !
If you are using these :

Any 150gr FN or RN load data would be/ should be appropriate and safe. All fails, confused ? Ask away ! Thats what we're here for.
Where you will notice the difference is the velocity and chamber pressures. They wont match exactly as listed in a real rifle anyway, as testing chambers and real rifles are fairly different.
Remember, start low, and work up.
