Here is a poser;
I am interested in trying some different thermal\night vision products. There is a company in Dallas that rents thermal and digital night vision products. The digital product is Pulsar N750 and it has an amazing picture on full moon nights without the assistance of IR illuminators. The thermal products are the ATN Thor line which was a big hit at last year's SHOT show. At that time ATN claimed they could be used on up to a .50 caliber. They now have downgraded that rating to a limit of a .308. So my question is how does the shock/recoil of the 450BM rank and would it fit within the allowable guidelines that ATN has set ? The Thumper is just that, a good thump but not the shock associated with other rifle calibers so I am thinking that we should be ok. Am I wrong? The owner of the company does not want me to use a thermal sight on my 450 until we get some clarification. Until then I am using a thermal handheld for spotting purposes and then stalking close before switching to the gun mounted digital unit. Not a bad system but the digital cannot see into brush\cane like a thermal can.
BTW - Tyler Adair at http://www.thermaloutfitters.comis a good guy to do business with. I can vouch for their products and service.
