Back in the late 90s RL-22 had a problem and they did a recall on that powder as it wasn't mixed properly and it had a high pressure spike. I had about 15 lb of this powder and I called and they told me that the samples that they tested had a spike of about 87000 to 95000 PSI, I used this powder, had 15 pounds of it, till after the 3rd round of all the primer pockets enlarged. That said action is still running today and is good shape, it's a blueprinted 700 action and it shows no sign of stretching or bulging of the action
