I have a chance to buy a Remington M-81A in 300 Savage. I have never reloaded for 300 in a auto rifle do you have to use harder primers. like in a M1 or M1a.

I've not heard of a slam-fire with a Remington 81, but I suppose it's remotely possible. I had one of these in .300 Savage years ago. I used CCI-200s without problem. Surprisingly accurate rifle with cast or jacketed bullet loads, despite the coarse front sight. The newest 81 is approaching seventy years old. I wouldn't load ammo for an 81 quite as hot as I would ammo for a bolt-action rifle.
 
I have written here many times about the .300 Savage and the M81 Remington. Don't worry about primers, standard LRPs are OK. You will find you will have a sore shoulder after a few rounds of factory-strength loads are fired. The long-recoil system is just that way. If you reload, I would stay in the bottom end of powder charges. I often use gas check lead bullets at a MV of around 2000 ft/sec. The action will still function reliably. Easiest case ever to re-form. Run .308 brass through a .300 Savage FL sizing die and cut and trim the case neck to the maximum case OAL. The only significant differences between .308 and .300 Savage cases are the neck length and a slightly different shoulder angle.

It's not too difficult to disassemble the M81 action entirely. Some YouTube videos are available and will show you how. You need no special tools to remove the barrel from the barrel jacket, but you do need to know how it is done first. A small screw-type hose clamp helps however. That shouldn't be needed often anyway.
 
I've had several Savage 99s in 300sav and presently have a Rem 81. I load same primers, just standard LR for both. Loaded 35R for 8s & 81s over the years with standard RPs with no slam fire problems. I've never heard of it being a problem with 81s.
 
The earliest production Model 8 rifles were apt to slam fire if a round is placed directly into the chamber and then the bolt allowed to slam shut full force by simply disengaging the bolt release.
Not all the time, not every one, but it was a known possibility with them.
They had a free floating firing pin. No spring loaded rebounding feature so once in a while with the right conditions,,bang.

Loaded from the magazine, the first round slam fire issue is not the problem it is as above.
But you can often load the early rifle that way, then eject that round and see the very faint mark on the primer from the bounce back of the tip of the firing pin .

Remington took care of that by making the firing pin a rebounding style with a coil spring surrounding it.
The bolt is slightly different as the firing pin hole is larger in dia in them for the spring and the firing pin is slightly dif in shape also.

All the Model 8 from there forward and all Model 81 production have that spring loaded rebounding style firing pin.

But always point the rifle in a safe direction when chambering a round. Nothing is 100%
