I really like the 375 cal have dreamed about a 375WSM for years even played with a few 300 WSM cases inserting 375 cal bullets into them when the 300WSM was first introduced. I feel it would be optimum for North American game/hunting especially in an AR platform. I currently shoot 14" and 21" barreled T/C Contenders in 375JDJ, 22" barreled Prohunter in 375H&H and 21" barreled Rem 700 LSS in 375RUM. I also shoot several 45-70 rifles a 458WSM in an AR or even a bolt rifle would also be super cool for bear defense unfortunately living in British Columbia, Canada our Canadian firearms laws prohibit us from taking AR rifles into the bush currently can only take them to a gun club and soon under the virtue signally spawn of Fidel Castro Prime Minister Justin Trudeau we will be facing New Zealand gun restrictions. With all that said my current truck gun now that hunting season is over for the year and bears are snuggled in their dens is my 22" factory tapered/fluted Rem 700 LTR in 6.8SPC it sits in a Magpul Hunter 700 OD green stock I use MDT 5 round metal mag that I tweaked the mag lips on hold 5 6.8 and their ten round 223 plastic mags they hold eight 6.8 rounds I use this combo for coyote, wolf and cougar hunting.
