Some minor observations:
-- Would this not suggest that the issue lies with the manufacturer? If the gun was not test fired (and why would it be to fit a recoil pad?) but the pad came loose upon firing, would it not stand to reason then that the screws were too short from the original packaging? Had this issue been brought to the attention of someone at Epps, it is reasonable to assume that they would have replaced the screws with a longer set without incident.
-- Ordering gun parts, especially barrels, out of the US is a costly and extremely time-consuming process. If you have never tried to import gun parts, take a minute and read up on the procedures outlined on the Epps website under Policies and Procedures. These steps are to bring a gun across the border. However, the process is nearly the same for parts valued at greater than $100.00, requiring detailed export permits, export licenses from the US-based seller, and importation permits from Canada Customs approved by the BATF and the US Department of State. Lengthy delays are becoming more and more common, with many guns and parts taking in excess of 6 months to cross the border. Just ask any Epps customer (or staff member) still awaiting delivery on guns that are now far overdue.
-- If you had ordered a stainless barrel, it would not be blued. Epps does not have the facilities to apply bluing to stainless steel. Rather than "feeding [you] a line of s**t", as you claim, it is likely that the person to whom you spoke was quoting the delivery time for the next existing batch of parts to be blued without realizing that your stainless barrel would not be included in that batch. Had you noted to that person that the barrel in question was stainless, you might have been advised of this.
-- As previously noted, if you were not happy with the fit and function of your gun, why was this issue not brought to the attention of someone at Epps? A home repair job with a Dremel tool is not gunsmithing. Should you not have considered having the qualified gunsmith who worked on your gun reexamine and complete the repair if it was lacking? Should you not have discussed this situation with a representative from Epps rather than bring it up here for the first time in a public forum?
And finally:
-- Since the OP of this thread was looking for advice concerning stock bedding and barrel floating, what purpose does it serve to suggest he contacts a gunsmith, who by your own admission, "is not keen on bedding rifles"? Kind of like asking David Miller to suggest which handgun one should buy, isn't it?
Again, just some observations.
