The only ammunition that should be used in a 30/30 is 30/30
As generally used terminology, no.
Winchester 150 grain 30-30.
If it's checked out by a competent gunsmith and given a clean bill of health, yes.
About 300 meters, depending on the rifle, sights, ammo, and skill of the shooter.
Gun shows, gun shops. A very common rifle cartridge.
I assume you mean .35 Remington rifle ammunition vs. standard 30-30 rifle ammo. If so then they are not the same and although they look similar they are not interchangable. I hope this answers your question.
No. Use only what is printed on the barrel.
None... it is the same sized bullet (.308 diameter). You have to choose the selection of bullet when reloading 30-30 ammo for the type of bullet. A pointed bullet in a tubular magazine can present a problem when the rifle recoils. The ammo is not interchangable, you must shoot the ammo that the rifle was chambered for.
Depends on the .30 cal. For 30-06 ammo, the retail sales price may vary from about .30 to .50 (in US dollars) per cartridge.
The barrel should be stamped 30-30 winchester.
ABOUT 200 yards, depending on rifle, ammo, and what you call accurately.
30/06, 150 grain
