Yes - LE are made for tube mags. They dropped a rifle from around 15ft with a loaded mag over 10,000 times and did not have one discharge from the blunt force. Extensive testing also occured from firing rounds 10,000-15,000 rounds.

Likewise new firearms to market and existing firearms subject to part revision changes are subject to 5,000-15,000 test cycles before production ready to market.

Hornady would not market an unsafe bullet. Load up your mag to the max.
