Yeah, there's absolutely no reason for a load cartridge to go off while the body's being resized.
The only problem with a body die is some have pretty tight necks, but a body die for a larger-caliber cartridge on the same basic case often works, since there's some variation in sizing dies. My Redding 7x57 FL die apparently has a slightly smaller base, and has slimmed down quite a few .257 Roberts cases that would work in one of our .257's but not another. Which is yet another reason I usually don't sell dies, even if I no longer have a rifle in that chambering: With a wide die selection of dies you can often solve such annoying but relatively minor loading problems.
This is the answer ^^^^^^^^^^^^^
