This will be another one of "those" threads.

If I might interject a quote from a recent review...

"If the barrel of the Genesis is indeed the same exact "turn-in-28 inches" twist .50 caliber barrel that is found on the Traditions muzzleloading rifles, it has only been proof tested by the official Spanish Proof House with a load that generates under 10,000 p.s.i. Still, the new Remington catalog and the Remington website tout the use of magnum 150-grain charges of powder. And I know for a fact that independent testing by one shooting industry manufacturer has found that with Triple Seven, such loads can push internal barrel pressures up over 30,000 p.s.i. I'm not saying that Remington's new Genesis is dangerous with such loads, only that there is way too much unknown between the level at which the barrels have been proofed and the pressures that the recommended powder charges are known to produce. Hopefully, Remington Arms will take it on themselves to extensively pressure test the questionable Spanish made barrels. Most of us in the industry feel that other muzzleloading rifle makers using these barrels have not made an honest attempt to do so. And, if they have, they've sure kept it an industry secret."
