We load a very similar load but an 123gr. SST and 8208. Our load is 27.7g and its not compressed but very close, anything over 28g and you could defiantly hear faint crunching when seating the bullet. We also seat a bit deeper however at 2250 COAL. Be careful with 8208 it can spike in pressure quickly especially when your close to the lands. There must be something up with you scales if you can shake and rattle the case ????
