We all have ideas, but are not fully equipped to explore them.
For example, most all of us have had an idea for a particular type of bullet, but are unable to fully explore the idea. For some reason, (usually money) one cannot produce the bullet to test.
So this thread is dedicated to those slightly off-center but seemingly reasonable ideas.
Here's my slightly off-center idea.
I have a CZ 527 rifle in 7.62x39mm. How about a 7.62x39mm (+p) loading? There are several bolt action rifles made commercially along the lines of the CZ (essentially a smaller but strong Mauser action). However, these rifles are all limited to the factory loading suitable for use in SKS or AK type rifles.
No. I do not know the pressure limitations possible. I do see from the SAAMI website, 7.62x39mm normally has a crusher test pressure average of 50,000 CUP (Copper Units of Pressure) [listed on page 12] and a piezo rating of 45,000 psi [page 24]. I am assuming (not always a brilliant method, but seems reasonable here) the pressure limits are predicated on use in the SKS or AK type actions.
I should think the Mauser type action is stronger than that.
Also, consider the precedent. The original .257 Roberts is now available in the .257 Robert +p loading, the Super .38 is really a .38 ACP +p loading, and a number of handgun rounds are similarly loaded. Not to mention the loading data for .45-70 Springfield, listed as 'trapdoor', 'lever rifle' or 'full power'.
So. What ideas do you have?
