Back from 1991 to 1995 I owned a 760 in .35rem. Reloaded for it and shot a number of deer with it. I presently own a Marlin 336 and consider it to be a superior hunting gun to the Rem. 760.
The things I didn't like about the 760 were that the forend "rattled" as it had a necessary amount of play, just like the Rem.870 shotgun. Secondly, the forend required a bit of reach to operate so the ergonomics weren't as good as the Marlin.
My handloads were a bit warmer than factory and were above the listed maximums for the Marlins. Ditto my current loads for the .35 Marlin.
You won't see 2,500fps with a 200gr bullet, but from the Rem. 760 I was able to get 2,400fps with H322. This load was also tack-driving accurate from the Rem.760. I was able to get a couple of 3-shot 1-hole groups with it. (200gr Sierra RN, my second favorite bullet from this cartridge).
The .35Rem is one of my favorite cartridges. At 2,300fps my current load utilizing the Rem. 200gr Corlokt has taken several dozen deer and several pigs. The Marlin is not quite as accurate as the Remington was but is no slouch. It routinely gets 1.5moa for 3-shots and I've shot 1" groups at 185yds (max distance I have on my backyard range).
I have't shot it as much since I got a .338ME and a .358win from the widow of a friend. The difference between the .358 and the .35 wasn't as much as I'd expected. The 20"bbl of the .358 BLR only gives about 200fps more velocity with an additional 8.0gr of H4895 which is the powder I use in both. IMR3031 will give an additional 50fps from the Browning but isn't nearly as accurate.
The reason for the near equality of the .35 to the .30/30 is that the factory ammo is loaded so light in the .35. As John Barsness once said about the factory 6.5x55Swede ammo, they're loaded to the level of "burrito gas farts"..... About as apt of a description as I could make.
Having used the .30/30 for nearly 50yrs and the .35 for almost as long, I can assure you that a .35Rem loaded to the level of the 1920's "Express" loading by Remington (2,250fps for the 200gr bullet) the .35 is on par with the .30/06 for on game performance out to 200yds.
A properly sighted .35 with current ammo (typically ~2,000-2,100fps) sighted to impact 3" high at 100yds is only 5" low at 200yds, so is a point and shoot to that range for deer, black bear, and pigs. Inside that range, it's hard to beat.... Only advantage the .30/30 has is cost and availability of ammo. (btw I also have two .30/30's, and shoot/like them too, especially with cast bullets...).
For a better appreciation of the .35 for those who don't reload, try the Buffalo Bore 220gr or GeorgiaArms 200gr CorLokts at 2,200fps. I've used the Hornady 200gr FTX but can't get excited about it. The one I shot an 8pt with failed to expand. Killed the deer (drilled heart), but it left no blood trail and had to use dog to find it.... (Ran 120yrd in dense woods....).
