I recently purchased a "new" Investarms Hawken from Dixie Gun and the barrel had a date stamp of 2017. I thought that was strange at the time but the barrel looked fine. Now I have come across this post from mmull56, "Lyman GPR's are no longer available from Lyman and this has sparked a lot of interest in buying one while they're still out there. Just remember there was a recall of 2017 models ser.#'s A595960 thru A599026 for possible breach failures. Check before you buy, I'm sure some unknowingly slipped through the cracks!" My serial # is A598564. Investarms was making the barrels for Lyman so those were Investarms barrels I'm assuming. Did I get a barrel that was sent back as a recall and then cycled back out to me as new? I know GPR barrels are generally longer and have a different twist so would those numbers apply to me? The failure was that the threaded part of the breech plug would break causing the barrel and breech plug to separate. I don't know what to do here. Maybe secure the gun to a tire, put a long string on the trigger and proof it with about 150 grains of FFFg?
