It can happen any time you shoot cartridges designed for rifles, ie. 300 savage, 7-08, etc. These were made to perform at higher pressures than the contender frame is designed for. Thus lower charges being required to lower the pressure.
However, sometimes, a faster burning powder can attain the same velocities with lower pressures which are suitable for the contender.
Example, I use H322 in my 300 savage. Using CCI 350 mag primers and 130 gr. Hornady bullets. I chronographed these loads at 2500 fps +/-, with very little pressure signs. Cases extract easily, primers don't crater and I get a full powder burn.
Basically, any large bore, designed for more than 43,000 in pressure, from what I have been told, will stretch the frame. And I may not take as long as you would think. :-)
