Do straight walled cases REALLY last longer when reloading?

Hubel brought this issue up, and, if it's correct, then one has to take a very serious look at the straight cases vs. shouldered, and factor in another point in the equation.

Makes the 458 Lott look VERY good...

I think the opposite is the case. The belling and crimping on a straight-wall case, as opposed to the crimping only on a bottleneck case would appear to work the brass more severely. I know I get more splits in my 357 cases than my 30-06 (come to think of it, I don't crimp my 180 grain Sierra Spitzer practice rounds).

I admit that I have not kept a strict accounting of how many times each and every case has been fired. One day, I am going to take my reloading equipment to the range and do a real experiment.

H.C.- Socrates wasn't comparing pistol to rifle.
Pistol cases have lighter construction.40 years
of loading straight brass(458 Win,my 458)the
belling and crimping never caused problems.Never
had a split there ever.The cases stretched ahead of belt and got thin, as they lengthened. If on rifle case belling and crimping is a problem it is
not being done right.

Also the neck is worked IN by the resize die,
then on downstroke worked OUT by the expander;
on bottleneck cases.And thats a little more flexing the brass.ED

The 458 Lott is looking better all the time, for a heavy mag rifle.

HenryC470,
From my experience Straigh walled cases that I load last significantly longer than
bottlenecked / shouldered cases.
hubel458 is correct in the way the die works and it does work the brass alot more
which is one of the reasons I think the brass of bottlenecked cases split at the neck
and on the shoulder.
Hope this helps
