My hang up with what has been presented as to how the situation has been handled is the same as @OutdoorAg has expressed above. I couldn't be convinced that a magical bedding job would have resulted in anything different with the particular stock the OP has. Energy is still being transferred through the lug into the stock directly behind it, and that area of the stock appears to not be reinforced. Is Alterra producing $600 rifle stocks whose strength is solely reliant on end user recoil lug bedding capabilities? If there product is walking a thin line on end user skill making or breaking the success, you would think that they have an expectation for a certain amount of failures, two referenced in this thread, and have a more effective customer service response. Again, no customer service is a choice and only takes effort with a minimal amount of people skills.
I’m with you. Doesn’t make sense to sell that stock to the layman rifle owner if it requires additional bedding, then take a run-out powder when it goes bad. They should require that they be the one to bed it, set up authorized gunsmiths to bed it, or produce a stock that will work adequately as a drop - in. Regardless of what we see written on forums, proper bedding isn’t just a matter of some clay, paste wax, and some JB Weld or the like.
There might be a failure to communicate on the manufacturers part here. Would be nice to hear from them. I’m in the market for a lefty Tikka stock. I am competent at stock bedding but I’ve made my share of mistakes also.
