I totally agree with Thunderbox and I had no intention of doing anything to the rifle until I properly understood the rifle and could shoot it well. His advice is pretty logical and it is something I will stick by for sure. While it is too early for me to seriously start considering accurizing the rifle, I don't think it hurts to ask how the bedding works on the SMLE because I am genuinely interested.
@Robert I'm in Canada, where No.4's seem to be more popular than SMLE's.
@Flying I don't really have anything specific in mind, whatever can be bedded and should be bedded to improve accuracy on a SMLE.
