goodbread,
First off, please accept our apologies for the slow replies. It's a lousy excuse, but with all the shows lately, SHOT, SCI, RMEF, and a hunt or two for good measure, we've all been swamped, (and I use that "we" loosely as there aren't THAT many of us) it's just hard to keep up at times. One of our Customer Service Reps brought your post to my attention so I'll try to answer your inquiry.
Left handers have always been a dilemma for the firearms industry. Obviously, there are fewer of them and consequently purchasing power is commensurate. Nearly every significant company in the business "attempts" to cater to the left handed shooter, and yes, because of the costs associated with engineering, tooling, raw material cost, manufacturing, assembly, packaging and then inventory carrying costs, not to mention liability insurance, attorneys, sales staff, marketing costs, and a marginal profit (ok, I'm sure you get the picture) we've all tended to focus on what would sell to the "bulk" of the left handers, leaving out customers such as yourself out. IF, we were to pass on the costs to accomplish smaller custom projects such as these, and trust me, we've tried, the customer hasn't supported the effort with their purchases.
We purchase our barreled actions from Anschutz, both Deter and his son Jochen are fine firearm design and manufacturing men. If they chose not to produce a left handed action, it was likely for the above reasons. And with out the base barreled action from them, it's virtually impossible for us to provide a Weatherby verison.
goodbread, I understand your frustration, you are not alone, as I'm a lefty as well. But I do understand the "other side of the coin" and hope my explanation helps.
And please accept our apologies again for the slow response.
All the best,
Brad
