Blacktailer,
Yep, less heat-sensitive powders have made a BIG difference over the last century-plus!
Have seen a few double-loadings with CRF rifles, caused by short-stroking. The one I remember most was during shooting at a simulated charging-buffalo target in Texas, and the guy short-stroked a Kimber .308 Winchester! However, the prize for winning the contest was a Tanzanian safari, so there was some pressure to shoot VERY quickly....
