While I do not advocate it, my Mode of 1917 rifles are way out on the ragged edge of field reject. Just about fail.

No issues (so far) as long as the brass stays with that chamber.

It is going to fire form out a lot and stretch as it does that and may lower case life. I don't shoot huge amounts though so don't know for sure.

Definitely more better not to stretch them any more than the minimum needed.
