If that Federal load is with the standard American 170, it develops only 2103 foot-pounds ME. That's only 100 ft/lbs more than the original round developed, throwing a 244-grain slug.
The military SmE load with the 178 was right up there with the .30-'06.
I would think the rifle should be safe with the Federal loading; the load you are proposing is much gentler than what the Army was running.
Good advice on the loading, too. ALL post-1891 Mausers, Rosses, most Mannlichers and a whole bunch of others MUST be loaded through the magazine to prevent damage to the extractor. This is not NECESSARY on the Lee-Enfield..... but it sure helps.
Enjoy!
