[QUOTE="Kennibear, post: 897716, member: 51650"] No offence swamplord but you are stuck on big case 375's. More power to you. But Lefty pointed out something you continue to ignore, no development in 375 caliber. None of those bullets breaks 0.500 in BC. That sucks bad! 308's have gone from the low 0.4's to the mid 0.5's for 180gr in the last few decades. But 375's are stuck in time. As to your other point about standard 375's being Factory ammo medium range weekend hunters you are very wrong. Two years ago maybe but not now. Up until I bought my 375 Ruger I could count the number of people I'd met with 375's on one hand, actually know twice as many who own 458 WinMag's. But when I went to buy a 375 Ruger things had changed. Federal Way Discount Guns couldn't stock them reliably. I placed my order for one and it took three months to get it from Savage. Very few people knew Savage made them so there wasn't a run on them. The Cabela's gun guy (Lacy WA) told me he sold every one of the Rugers he got in within hours of them hitting the rack.

Sportsman's Warehouse in Federal Way could only get a dribble of them and they sold everyone as soon as they came through the door. Fast forward to 2013.
