My Uncle and a couple of cousins that use them and swear by them.
My Uncle has one each, on a .300 RUM and a 7mm STW.Don't know the models type per say but I do know they were the ones that first came out with the ballistic plex reticle and he paid around $400 American for them at the time. He uses them religiously on his two rifles and between his rifle handloads and this scope and his shooting abililty can nail 10inch pie consistantly out to 800 yrds with both caliblers..He swears by these scopes clarity, toughness, and quality..
