Good thread even if it started out a little older it is a question many have.
My last rail was not EGW but they do make great rails.I had to bed it at the rear as it was kinda high but no biggie.
I just installed a rail from OuterImpact.Its thick and did not need to be bedded at all.I put a staight edge on the rail and super straight.
The receiver is a Howa mini action so the rear of the action is stepped down so no way to use a straight edge on it.First one in a long time that did not need bedding.
