Just food for thought.I've used Buf Bore ammo quite a lot, including in my .35. Surprisingly, the 220 Speer flat nose does less meat damage at close range, say inside 40 yards, than the factory 200 Core-loct. Seems it's going too fast to expand much, and I've yet to recover one in a pig or deer. Their .45 Colt offering was quite impressive too, and both the 260 grain hp and the 325 grain hard cast were great shooters out of my Marlin 1894 Cowboy comp., and one shot killed two pigs at once! To be fair, the first was a small yearling, that I couldn't see in front of the sow, but the bullet passed through one cleanly and smashed the shoulder and jaw of the sow, who quickly crashed into the brush. As I approached, the piglet gave one last squeal and that enraged the sow enough to rear up on her hind legs and come after me! I'm sure she was working only on andrenaline and motherly instinct, but it was the first time one has tried to take out a piece of my hide, and a follow-up shot really wasn't neccessary as we found the damage from the first shot more than enough, and she would have just expired were she lay if it wasn't for my clumsy crashing through the bush and being a large target.
The BB heavy .35 ammo had twice the recoil of the factory 200's, but the 220 JFN has the same energy and velocity at 100 yards as the 200 Core-loct has at the muzzle. I'm quite sure that it is capable of taking elk at 200 yards, provided you know the exact distance and drop of the bullet plus good shot placement. At 150 yards I believe it is capable of taking most critters in North America, and if a buffalo or grizzly can be killed with a large caliber black powder percussion rifle, then it isn't a great leap to trust a hot loaded .35 to do the same. PS-Just because I believe it's possible, doesn't mean it's common or easy. I'm just saying that if it is within each shooters capability, practice and common sense, it's possible.
In "my opinion" if you hunt brown bear with a 35 Rem. you might want to have your same guide with his same 375 H&H with you just in case. I know back in the early 1900's the 30-30 Win. and the 35 Rem. were use for all kinds of game including "big bear's". Just remember one thing, at one time if you wanted to go from New York to California you had to ride a horse. Times have changed you don't have to ride a horse from N.Y. to Cali anymore, and there a lot better cartridges out there for brown bear hunt now, I'd get one and use it. Again just "my opinion".Pa Ridge Runner said:I killed two moose and a brwn bear in AK with a 70#bow my guide carried a backup rifle in 375 H&H each time.
