Speer 13: "We are occasionally asked if the 30-30 can be loaded to higher velocities in a modern bolt action like the Remington model 788. The answer is NO! The 30-30 case is an old design with relatively thin walls. Attempting to load "hotter" would risk a dangerous case failure."

I think you could make a better case for Big Foot, UFOs, and global warming than you can for what Speer 13 says about 30-30 case strength.

At least there is some doubt in the other nut case ideas. Speer 13 is too easily dis-proven.

What measurable good are they going to get from a magnum primer in the little 223 case?
I can tell you what harm.. an extra grain's worth of pressure without an extra grain's worth of velocity.
That's a poor trade off.

I am putting 34 gr W748 220 gr in a Sav 219L 30-30 for 83kpsi.
I have tried a number of brands of brass, and that brass must have not read Speer 13, because it has long brass life.

I am shooting 223 above max published loads because the .223 got SAAMI registered at 55 kpsi, but the 1950 .222 Win case head has long brass life at 75kpsi.
