I really do think this is a myth. Save for the bad bridge plug design on the Apollo, pressure hasn't been a problem. One thing to consider. He recommended 150 grains of pellets with the 348 PB. This is not shying away from pressure. Just ask Leymoyne what his strain guage says about 110 grains 777 and 150 grains of pellets. I haven't a clue what the the limit of 2f RS is in an Encore Hank, but if it is 120 grains, then comparable quantity of 2f 777 is 100 grains. All magnum rated BPI products are rated for 100 grains of 777 2f. Cayugad has confirmed this. This isn't a "pressure problem" issue. No more than 100 grains of any 2f granulation powder to include 777, lets not read into that things which are not there.

Again the maximum load is 3 pellet/348 PB, not a wuss of a load, very, very, stout and they ain't shying frompressure. The real risk is loadingerrors guys.The difference between a spanish barrel an american barrel as compared by the ratio of burst pressure to maximum load operating pressure is small, if there actually any difference, we literally have no proof there is any difference.

In any event, it is wise tothink long and hard about how much yieldone put down the barrel. Make a mistake with 70 grains, you might not know the error was ever made. Make a grevious mistake with 150 grains of pellets, and you could have a serious accident.
