LGF,

A double rifle action is not nearly so strong as a bolt action rifle. Consequently, the working pressures are much lower.

Often with a bolt we read pressure signs by the shape of the fired primer - flattening, cratering, etc.; the case bulge just in front of the web; sticky extraction, etc. You can't rely on these signs with a double rifle because by the time any one of them shows you have far exceeded safe pressure.

With a bolt or single shot there's no issue of achieving proper regulation. However, that's of great importance in a DR, and it's usually tied closely to bullet weight.

DR's often appear in obsolete and obscure calibers, and in many instances these cartridges weren't subject to industry standard. We therefore see variations in chamber and barrel dimensions that must be heeded.

I'm sure there are half a dozen other issues that set DR's apart. A novice reloader will find success with a .30-06 bolt gun without damaging the rifle or his face and hands. He should master that before even considering a DR.

In the end, I'm not the reloading police, and everyone is free to chart his own course. DR's are not the same as bolts.

P.S.

Remember this is a thread about DR values. Thus, I wasn't going to expound about reloading.
