That particular bullet is intended for serious work, not paper punching like the Sierra Match King bullet. As a "working bullet" they have to function in all kinds of conditions, including mud, sand, dirt, water, etc. That's why they have the cannelures, so the case mouth can be solidly crimped into the bullet. There would also be waterproofing compound applied to the case neck before seating the bullet. They're made for rough treatment and are intended to fire when the trigger is pulled. They're also intended to shoot "minute of enemy", and aren't intended to be target bullets, though I've gotten some surprisingly good groups from them with my M1A's when loaded properly.
If you'll seat to the bottom cannelure and crimp into it for your Garand, you'll be fine.
Hope this helps.
