[QUOTE="Fiftydriver, post: 589533, member: 10"] So you have no explination for it???? If you look at the old load data that also was established under the SAAMI standards, the old data showed much higher performance levels then todays standards. Its the lawyers alone that have come up with these anemic standards and noone else. Do I advocate exceeding safe chamber pressures, certainly not, especially for novice handloaders. But for experienced handloaders who PAY ATTENTION to all pressure indictors, its easy to find a safe max working pressure. The Rem Mag, IN NO WAY AT ALL, spikes chamber pressure compared to the Wby. The only thing that will do this is the difference in the throat between the two but both will easily handle the same chamber pressure quite safely. If you set up a Wby chamber with an accuracy throat which is short like the Rem Mag, they are for all intent and purpose IDENTICAL. Again, this is a lawyerproofing step pure and simple, this is also the reason factory rifle triggers generally are quite bad right out of the box on most rifle, to keep the lawyers off the manufacturers back. One more question for you, say you take a 7mm Wby rifle, load it with say a 140 gr Accubond to the max load used in the Nosler reloading manual, what happens with that load chronographs 100 fps slower then the book says it should, does that mean your rifle is producing 100 fps less velocity at that top working pressure listed by the reloading manuals????
