Re: Barrel blew apart.
EVERYONE wants to get the "ding-ding-ding" "RIGHT ANSWER" award.
1. My view of the pics doesn't really show whether the color is copper or fine rust. To me, it looked more like rust. Need to see in-person to guesstimate, swap with a Q-Tip and test to know for sure.
2. Yeah, it has a lot of the look of a bore obstruction...but then again, not really. Those I've seen showed a more obvious rounded "bubble" in the bore at the point of impact than shows in this blown barrel.
3. The split being two fissures about 180° apart strikes me as a bit curious and perhaps indicative of a materials defect in the steel.
4. Assuming for sake of argument that the rifle's history and the events immediately before the blow-up are accurate, I believe the following:
A. A manufacturing and/or materials defect in the barrel led to a crack or cracks on opposite sides of the bore, which rusted over the years and induces huge stresses in the adjoining steel. Rust is more bulky than the source steel, remember?
B. The crack and rust provided the point for a splitting failure to initiate with the fairly "low" pressures of about 10,000 PSI to be expected that far down the bore.
C. The split propagated through the steel along the lines of a previously-latent defect in the material.
D. Remington will at least replace the barrel, and perhaps the entire rifle, as a fairly low-cost way to preserve goodwill by providing out-of-warranty coverage, regardless of whether an ammo defect contributed to the failure. Look at the failure rate--a few hundred bucks as compared to how many thousand(s) of rifles which have no problems?
E. If it's clear that the client wants only a simple demand letter and communication of the results, the attorney's fee could be as low as $100 if your area is low-priced and/or the attorney is very "hungry". Most likely $250. If you drag the initial consult out to a full hour telling and re-telling and pontificating on your story, then it could expand to $1,000.00 easy. If Remington sends the stuff back and says "tough tonails", the best approach might be just a small claims action, but you're best off doing it in some state where they have a bank account to collect on. They would argue depreciated value of the entire rifle, you would argue full current replacement value, and either side could win that part of an otherwise losing case for Remington.
I'm for materials defect, possibly made worse by maintenance issues which are really a red herring because who can assure than the oil in the bore really will penetrate the crack caused by the defect.
