Firing pin probably gummed up, a few drops of 3 in 1 oil on the pin cleaned with a q tip and reoiled should help. The lever issue should be easily fixable if I remember correctly. One of the most accurate guns I have ever owned. Plenty of videos on UA-cam on how to take apart and clean .
Never seen a box of Nosler 30-30 ammo. Does it say on the box anywhere that is light, or light recoil? I have always seen 150gr 30-30 at advertised velocity of 2390.
My 50's vintage 336RC will not reliably strike CCI primers. It fires flawlessly with Remington & Winchester primers. My best accuracy is with Remington brass & primers, 150 grain Speer Hot-Cor flat nose bullets with a 35 grain charge of W-748. Good luck with your gun, we've seen those lever action Marlins quadruple in value over the last 30 years.
I'm still trying to wear out the 336 I got when I started hunting. It's still puts venison on the table. I have other guns but the 30-30 still goes for a hunt every year.
Some 336s have a problem with light strikes due to the two piece firing pin producing unnecessary drag. Replace it with a one piece and problem usually goes away
Marlin misfires are kind of common. Two piece firing pin and rough surfaces on the rear portion of firing pin. I smoothed and polished mine but have not yet had a chance to try it again. Tons of misfires. I can’t trust it for hunting yet. Mines a 1984 date.
... that Tasco junk scope should be able to hold together on a 30-30 win ... good "cosmetic shape" might not be good shooting shape ... hope you checked the barrel with a flashlight ... if the previous owner(s) fired enough shots to wear out the lever retention pin spring the bore could be as smooth as a baby's behind

Your first group of five shots was 1/2 inch at 50 yards. That is outstanding especially with that scope.
You have found the reason it was in the gun shop! Should be an easy fix.
Good video. Sure is low velocity for a 150gr bullet. Most other factory ammo I have in 30-30 is averaging 2350 give or take.

never had a prob with mine .orignal owner 1979
I wonder if a previous owner lightened the hammer spring to get that glass-like action, and as a result caused the light primer strikes?

You can replace that plunger catch and spring pretty cheap. I had to replace a buddy of mine's Marlin 336. It was doing the same thing.

...last little bit of lever movement aligns the firing pin and sets the head space...
My 336 did the same thing … take it and clean the firing pin … gets dirty and sticks
Does the Marlin have a hammer spring?

Winchester 150 grain gives me the best accuracy in my 336.
Head space problem
A good cleaning might help just saying
