I have about 400 primers of these variety and I do not do pistol cartridges or whatever so I was wondering if I could use them in my win94 30-30 I know it says large pistol for a reason but?
 
No!

The only time I would even consider it would be with greatly reduced lead bullet loads.

Even then, they are not the same size.
The Lg Pistol primers are slightly shorter then Lg Rifle primers.

I'd try to find another reloader in your area and do some trading.

Trade them with someone who has large rifle primers but needs large pistol primers. Give him 400 pistol primers for 300 rifle primers, and you'll make a new friend.
It's never a good idea to use the wrong primers. It is always best to use the right components.

I've used large pistol primers in rifle cartridges, for light loads of fast pistol powders for breaking in a new barrel. But even changing from one brand to another changes velocity and pressure (Lyman 48th Edition reloading manual has a nice experiment on that) so changing to a pistol primer would truly give you unreliable results for both pressure and velocity. It ain't worth it.
 
Just to add, it would be in cast lead loads, with about 8gr of unique which is the minimum.. I was just wondering if I could, that's all.

Should work just fine *if* you seat them properly (below flush) and your firing pin projection is long enough. You don't even need to go that low with the powder; should be OK with any normal cast bullet load -- assuming your rifle will set them off.
 
NO.
There is a difference in the primer cups. I always understood the the primer cups on pistol primers are much softer and thinner metal, so can not stand up to the higher pressures of a rifle. You could stand a great chance of having a primer blowing out and causing damage or harm .
IMHO. it just would not be worth the risk aver the cost of a few hundred primers.
 
gun4funtime is correct, rifle primers have a heavier cup than pistol primers. Pistol primers can't take the pressure generated by rifle rounds. Like the others have told you, don't do it!!

Typical cast bullet rounds generate the about the same pressure as pistol rounds. The cup thickness shouldn't matter for that; but the seating depth is likely to cause a problem.

It's a poor idea, but I don't think it's dangerous.
 
I can not see how 30-30 pressures are going to be a problem. Full factory 30-30 loads generate approx. the same pressure as 44 magnum. How can a load that is 44 Special category violate a primer designed for magnum pressures. 8 gr. of unique is not going to create high pressure in a 30-30. Go for it and enjoy!!!!!!!!
 
MMCSRET is right, IMO. A 357 magnum loads develops around 35,000 PSI and a full power 30-30 can run up to around 40,000 PSI. Common sense tells you that is not a difference to worry about, at least in my mind. The primers in question are designed for these magnum pistol loads, and will actually be used in a much lower pressure situation. I'm a careful reloader, but I'm surprised by some responses bordering paranoia when someone wants to change a component that would not actually create a dangerous situation, when given proper thought.
If your rifle has no problems igniting the primers, I say load a few of your light loaded rounds and try them.

OK, OK, in this case the 30-30 will generate no more pressure than a 44 Magnum BUT, other rifle calibers will generate well over 50,000 CUP. In any event, it's a bad idea on many levels.

Really now, even at today's prices, is it really worth taking a chance especially for only 400 primers??
 
OK, it might be safe this time? how about just a little more powder??

Come on, We are talking safety here.

On the range when shooting, most will not put up with an unsafe act of any kind. most will not take a chance of doing something unsafe. Safety First. Why then would we even consider something that could be unsafe at the reloading bench for the sake of a few dollars?

The manufacturers make different types of reloading components for a reason. That is what will be safe to use. Why would we want to use mix matched components?

Buy a good reloading manual, follow the manufactures recommendations.

Remember, Safety first!

I don't think the mag pistol primers would be a problem with the cast bullet loads you mention. My recommendation would be to only prime and charge what you are going to shoot and not store any long-term. That way you would avoid the possibility of picking one up at a later date, pulling the bullet and recharging the pistol primed case with a rifle load.
 
Primer diameters are the same for rifle and pistol. One for large, one for small. Primer heights are different. This in addition to different "cup hardness" between brands.

So you run the risk of not setting one off, or punching a primer. Niether of these options are good. So, put the right primer in the right case and be done with it.
 
Thanks for the advice guys.. Looks like I'm not going to do it.. Hopefully i'll be able to find a trade or something.
