This is very interesting information.
I recently loaded a batch of 38Spl at max load using Power Pistol. i wanted to see how the various guns felt shooting "real" ammo.
The S&B primers extruded onto the firing pin and bound up the revolvers. Pressure is ok - but not with those primers. I guess magnum primers would solve the problem.
I was thinking of the primer problem when I was concerned about your hot load.
All reloading equipment and components have to be smuggled into Mexico, at some considerable risk. There is no place that sells them to you "over the counter". We imported (and I mean imported "under the table") hundreds of thousands of primers at a time for the San Miguel/Queretaro Club needs. Figure the guys from Mexico City and Guadalajara are doing the same using different methods. Also, Merida (with whom we maintain contact and a loose friendship but do not interchange much although I want to work on that moving forward) is another big player but their product arrives by sea instead of overland. Or at least, it's what I was told. We all lie to each other all the time about how stuff is done and never tell anyone, anywhere who is not directly involved in the "how", so maybe they misled me as well. I'd do it to them, too.) Usually CCI or Winchester being the favourites. CCI being the choice as they were probably the least likely to detonate under the rather primitive methods that were used early-on to bring in large quantities of primers.* Later on, methodology became more sophisticated and now they arrive right in the factory boxes. It was amazing to me -- and still is, in fact -- that a large "quantity buy" in the U.S. could be moved to Mexico with all the costs and risks involved and we paid very little more per 1000/count than retail ends up being here in Canada. Something's wrong there. Someone has their hand out a little too much on the Canadian side of things for it to be that bad for legal purchasers compared to the smuggled product. Just my opinion.
Anyway, we never had any problems with either Winchester or CCI primers and none of them were MAGNUM primers. All standard. Elmer also used Standard Winchester in his loadings I believe. I was considering getting the S&B primers to sell here in the store, but not if they give problems. They would come in 10.00 dollars cheaper per 1000/count than CCI or Winchester or Federal....but it's not worth it if they're too soft.
We did notice once some problems with some of the guns "sticking" on extraction when using Heavy Duty loads made of Green Dot. However, my own opinion is that the group of people experiencing the problem might have mixed (accidently) some Bullseye and Green Dot together before preparing the loads on a Dillon 650 because it only happened the one time and was limited to one "group reload" using that powder. At the Tulsa Gun Show in 2011 some of the Big Guns from the S&W Forum told me at the dinner after the S&W Collector's Association meeting that Green Dot had been used in .357 Factory loads for several years, so I think it was more an "idiot mistake" than a powder or primer problem. None of the San Miguel guys had any problem with their Green Dot H.D. reloads.
*Years ago, talking to an old lady at a dinner somewhere, she started to ask me about my interest in shooting. It came out that she had worked in one of the large Remington Arms ammunition plants during World War II. "I was up on a large winged balcony full of machines overlooking the plant floor," she told me. "I saw one of the men down on the plant floor below me walking through the machinery carrying two 5 gallon buckets full of loose primers, one in each hand." She paused for a second, and then said: "There was a flash, and he was gone. There was a lot of noise anyway, so I heard hardly anything but it's what I saw." True, or not? Maybe.
When I saw large bags of loose primers being unloaded one day I pointed out that this was really, really dangerous. I ran into about as much opposition from the Mexicans over this as I did for insisting that they not start drinking alchohol on the range until after the guns were put away. I was totally able to change completely the way primers are handled and moved but as for the drinking and shooting and shooting and drinking, I was only really able to stamp out that fire on the Practical Shooting side of things. The shotgunners and .22 Silhouette and Center-fire Silhouette, Live Pigeon, and Running Goat events are still a booze-fest free-for-all. Oh, well, I made some progress at least.
