I guess you and I think a lot alike. I have a new 340 Weatherby to hunt with this year. I also have a 378 Weatherby that I have hunted with since the early 80s. I put a break on the 378 a few years after I bought it because breaks were becoming popular and I wanted to try it. It sure did away with the recoil but I had no idea it was going to be so loud to shoot. I have to say that I am left-handed and wish I could find a left-hand 338-378. I love the 33 calibers. I'm afraid to call the Weatherby Custom Shop because they might tell me that could build me a left-hand 338-378 and then I would have to buy it. So, to the OP, try something in 33 cal. I think you will love it. Just make sure you have enough bottom metal for Long bullets and enough throat. The animals you shoot will thank you!If it has to be one of those, the 33 cause it will do everything the 28 can do and then some. However, since you already have a 7mmRM and 338 winch, why bother? .378 Wby maybe? 26 nosler? Cause you have 30 and up well covered, but nothing in mid range? 26 will kill anything in WY and most anything in AK, but you have better selections for those big cuddly Brown Bears than it by far.
