Would you shoot someone else's reloads?

[270man]

Gil & others, I won't say never but generally NO to shooting someone else's reloads. A few years ago another fellow and I were at the range shooting our 223 bolt rifles. We talked about our favorite loads and he gave me 5 rounds to try. These had a new powder that I hadn't used before. When the first one stuck in my chamber, he remembered that they had only been neck-sized. A rubber mallet opened the bolt but the extractor slipped off the case rim. Light tapping with a rod did not dislodge the round. Note that this is very dangerous, and it resulted in a deadly accident years ago at a local shooting range! I tried many things to remove the round. What finally worked? I put the barreled action in my freezer for a day, then was able tap out the round fairly easily. The expansion/contraction coefficients of steel and brass are different but I don't recall which is greater. Anyway, it worked when I took the B/A out of the freezer.
